Diabetes is a disease caused by high levels of blood glucose resulting from improper production of insulin or action of insulin. Type 1: In this Diabetes, the cells that make the hormone insulin regulate the blood glucose are destroyed by the body immune system.
Type 2: In this case, either the cells do not use insulin properly or the body does not produce enough insulin. Gestational Diabetes: Increase in the levels of blood sugar during pregnancy is called gestational diabetes. In year 2004, diabetes ( Both type I and type II ) was diagnosed in 1.4 million adults between the age of 18-79 years (Figure 1). The following table attempts to extrapolate the prevalence rate for Diabetes( both type I and type II ) to the populations of various countries and regions.Cure reasearch, Statistics by Country for Diabetes.
The Insulin market in 2006 was largely dominated by two players, Novo Nordisk of Denmark and Eli Lilly of USA. India and China are emerging as the most potential future markets for insulin delivery devices. Insulin pen devices dominate the market in Europe and Japan whereas syringes and pumps dominate the US market.
There was a big improvement in the global diabetes market for innovation particularly in the field of non-invasive methods of insulin delivery, including inhalable, oral and patch technology. Dipeptidyl Peptidase IV (DPP-IV) Inhibitor :DPP-IV inactivates glucagon-like peptide-1 (GLP-1), an important mediator of blood glucose levels following meals. Decline in the IP activity during 2005 and 2006 is due 18 months publication delay of patent document. The primary objective of this study is to assess the efficacy of SR141716 (rimonabant) compared to placebo on change in HbA1c and on relative change in body weight over 52 weeks in obese type 2 diabetic patients on monotherapy inadequately controlled with oral anti-diabetic drug (sulfonylurea or ?-glucosidase inhibitor). This study will evaluate the longer-term glycemic effect of two medicines approved for initial treatment of type 2 diabetes.
Balaglitazone is a thiazolidinedione derivative that is being developed as an oral anti-diabetic drug to improve blood glucose control in patients with type 2 diabetes. This is a 24-week study to assess the efficacy on HbA1c of 100 mg vildagliptin once daily as compared to placebo as add-on to metformin in patients with type 2 diabetes inadequately controllled with metformin.
The purpose of this study is to find out if Diazoxide can partly retain insulin production in newly diagnosed type 1 diabetes patients. The purpose of the study is to evaluate if supplementation with vitamin D in a dose of 40.000 IU per week will result in improved metablic control in patients with type 2 diabetes. The purpose of this study is to determine whether type I diabetics with carnitine deficiency exhibit increased numbers of hypoglycemic (low blood sugars) events and if unrecognized hypoglycemia occurs during continuous 72-hour glucose monitoring. This study, conducted at the Phoenix Indian Medical Center, Phoenix, Arizona, will determine whether reducing subclinical inflammation lessens insulin resistance in healthy, obese volunteers.
The purpose of this study is to collect important information regarding the glucose-lowering efficacy of MBX-2044 and the safety of MBX-2044 (especially weight gain and edema) in diabetics. The purpose of this Phase 2a study is to evaluate the efficacy, safety and tolerability, of multiple parallel doses of PF-00734200 following oral administration to adult human subjects with T2DM who currently are on a stable dose of metformin. The objective of this monotherapy study is to investigate the efficacy, safety, and tolerability of 3 doses of BI 1356 BS compared to placebo over 12 weeks of treatment in patients with type 2 diabetes and insufficient control of thier blood glucose. To evaluate the efficacy of a single injection of glulisine before the main meal added to insulin glargine plus oral antidiabetic drugs (OADs) compared to insulin glargine plus OADs in Type 2 diabetic patients poorly controlled with basal insulin plus OADs.
The purpose of this study is to determine if restoring normal metabolic function in patients with either type I or type II diabetes can improve the impact of the consequences of diabetic complications on the overall quality of life of diabetic patients.
This is a phase 3 trial designed to compare the effects of twice daily exenatide plus oral antidiabetic agents (OADs) and once-daily insulin glargine plus OADs with respect to glycemic control, as measured by hemoglobin A1c, with minimum weight gain, in patients with uncontrolled type 2 diabetes on OADs.
The purpose of this study is to see if giving exenatide and insulin before a meal would lower blood sugars after the meal. This study in Germany is designed to compare the effects of twice-daily exenatide plus metformin and twice-daily premixed human insulin aspart plus metformin with respect to glycemic control, as measured by HbA1c, combined with the percentage of patients with at least one treatment-emergent hypoglycemic episode. This study will investigate the use of rituximab to see if it can help lower the number of immune B cells thereby preventing the destruction of any remaining insulin producing beta cells that remain at diagnosis.

Effectiveness of Fenugreek for Lowering Hemoglobin (HbA1c) in Patients with Self-Management of Type 2 Diabetes: A Randomized Controlled TrialRashid Ansari1 and Saiqaa Ansari2[1] School of Public Health, University of New England, Australia[2] School of Population Health, University of Queensland, Australia1. Physicians began to see clusters, however, of nondiabetic men admitted to hospitals across Singapore with severe, unexplained hypoglycemia in February 2008.1 Several of these patients suffered severe coma and neurological sequelae. All patients underwent a series of toxicological tests and were questioned about their drug-taking history. The majority of cases were associated with Power 1 Walnut, an illegal preparation that claims to be an herbal medicine.
Most patients who were poisoned by up to five times the total daily recommended dose of glibenclamide were treated successfully in the emergency department without significant sequelae. Patients were examined on 1.5T and 3T MRI systems using conventional and advanced pulse sequences.
The MRI distribution and appearance of these lesions are not specific, and ischemia, hypoglycemia, and epilepsy may have similar MRI findings. Some patients also had abnormalities in the splenium of the corpus callosum and internal capsules. This is also called as juvenile onset diabetes as it occurs mainly in children and young adults. The incidence of diabetes was lower in adults having an age between 18-44 years compared to other groups (Figure 2).
Annual number (in thousands) of new cases of diagnosed diabetes among adults aged 18-79 years, in United States from 1997-2004. Gender based incidence of diagnosed diabetes per 1000 population aged from 18-79 years in U.S.
Incidence of diagnosed diabetes per 1000 population aged 18-79 years, by age in U.S from 1997 to 2004. Number (millions) of persons with diagnosed diabetes from year 1980 to 2005 in United States. DPP-IV inhibitors have been clinically shown to provide long term improvement of glucose control without the risk of hypoglycemia, and to improve the function of pancreatic beta cells, the cells responsible for the production of insulin. The purpose of this study is to assess if additional treatment with balaglitazone in patients with type 2 diabetes on stable insulin treatment will improve blood glucose control and decrease the daily insulin dose, but with less impact on weight gain and oedema. If they are determined to have unrecognized hypoglycemia, then oral carnitine supplementation will be given to those subjects and they will be reassessed for the number of hypoglycemic events in a 72-hour glucose monitoring. It will also provide important information about the appropriate doses to be used in subsequent longer-term studies to evaluate the safety and efficacy of MBX-2044 alone and in combination with other anti-diabetic agents.
Patients are treated once a week with pulsatile intravenous insulin therapy mimicking normal insulin secretion. The purpose of this study is determine whether hOKT3gamma1 (Ala-Ala) can halt the progression of newly diagnosed type 1 diabetes. The focus was the recent meta analysis published in NEJM, showing increase CV mortality with Rosiglitazone. Yet it is still very expensive and best for highly trained patients on intensive insulin therapy. IntroductionThe incidence of type 2 diabetes is increasing worldwide, resulting in large measure from the increasing prevalence of obesity (Yale, 2000). Profound hypoglycemia typically affects diabetic patients receiving treatment with oral hypoglycemic agents or insulin as a complication of therapy. This questioning revealed that their drop in blood sugar was due to consumption of an illegal product sold for sexual enhancement that contained glibenclamide or glyburide, an oral hypoglycemic agent commonly used for diabetes treatment.
These preparations had been purchased from unauthorized itinerant peddlers and makeshift stalls. Diffusionweighted imaging and T2-weighted MRI showed abnormalities in the hippocampus, cerebral cortex, and basal ganglia, sparing the subcortical white matter and cerebellum (Figure 1). These may represent a distinctive pattern of limited involvement on diffusion-weighted imaging (Figure 2).5,6 The abnormalities were not seen on T2-weighted images in some of these reported cases. From 1997 through 2004, the age adjusted incidence of diagnosed diabetes ( Both type I and type II )increased by 35% among men and 46% among women (Figure 3). Especially people aged from 65 to 74 had the highest prevalence compared to other age groups (Figure 5). The hypothesis of the trial is that the test drug, BI 1356 BS will lead to better control of blood glucose compared to placebo after 12 weeks of treatment. The panel consensus was that while awaiting more safety data, for now those patients who are tolerating Rosiglitazone should continue taking them, whereas newly diagnosed patients should try alternative treatment. Diabetes mellitus is a pandemic disease and is one of the main threats to human health (Narayan, 2005). Radiologists seldom come across patients with severe hypoglycemia, except in rare instances when abdominal CT is requested to rule out insulinoma as the cause. This wave coincided with a sudden increase in requests for MRI examinations of coma patients who had severe brain damage.


Forensic chemistry tests showed that the supposedly natural tablets were adulterated with glibenclamide and small traces of sildenafil, the active ingredient in Viagra.
These findings are consistent with previous case reports and animal studies that describe the selective vulnerability of the brain to hypoglycemic damage and characteristic lesion distribution in the cerebral cortex, insular cortex, and hippocampus. They may normalize rapidly on follow-up imaging and probably represent fluid movement rather than irreversible cell necrosis. The prevalence of the disease was similar in both men and women till the year 1998 but from 1999, the prevalence of the disease increased highly in men compared to females (Figure 6). Also all PPAR agonists should be treated as distinct entities rather than having class effect. The clinical cause of the coma is usually known, and the value of MRI of the brain to diagnose hypoglycemia or predict outcome is not backed up by evidence- based studies. Further follow-up studies may still be needed to better understand the mechanisms of these unusual findings.
It is projected that this number will be increased by 72% to 333 million by 2025, and nearly 80% of these cases will be in the poorer industrialized countries (IDF, 2003). According to a 2005 US Government estimate, approximately 21 million people in the United States have diabetes (Gerich, 2005). In 2002, diabetes was the sixth leading cause of death and had an estimated total cost of $132 billion (Hogan et al.
Type 2 diabetes is a disease characterized by a dual defect: 1) by insulin resistance which prevents cells from using insulin properly, and 2) degrees of reduced pancreatic insulin secretion.
A quarter of the population of Pakistan would be classified as overweight or obese with the use of Indo-Asian-specific BMI cutoff values. Jafar et al (2006) have reported that prevalence of overweight was 25% and obesity was 10% in a large population-based sample of people over the age of 15 years in Pakistan. On the age-specific prevalence of overweight and obesity, they found that more than 40% of women and 30% of men aged 35–54 years were classified as overweight or obese. It has been suggested in a variety of observational and epidemiological studies that physical activity may play a significant role in the prevention of type 2 diabetes mellitus.
The relationships between physical activity and overweight are only beginning to be understood for the adult population, sedentary behaviours, particularly watching television (TV) and videos, surfing the internet have been found to be related to higher body mass index (BMI) for adult’s population (Struber, 2004).
The literature linking physical activity levels with risk of overweight in adults is not consistent but physical activity is an important component of effective obesity treatments (Saelens, 2003). The main health promotion intervention here is the public health education which highlights the importance of physical activity for the prevention of type 2 diabetes in the middle-aged population of sub-continent and particularly Pakistan, which is experiencing a rapid and substantial decline of physical activity levels as a result of poor eating habits, unhealthy food supply, expansion of television, computerization, and mechanization, more prevalent car ownership and sedentary behaviour.
In parallel with decreasing levels of physical activity, the prevalence of overweight and obesity has increased significantly in Pakistan and as a consequence, diabetes mellitus has become a major public health issue. Therefore, promoting an active lifestyle or regular exercise has become the highest public health priority in that country to overcome the onslaught of type 2 diabetes.
Also, the search for dietary adjuncts along with usual medical care to treat this life altering disease has become more important and dietary supplements that can modulate glucose homeostasis and potentially improve lipid parameters would be desirable. Fenugreek (Trigonella foenum-graecum Linn) is a dietary supplement that may hold promise in this regard and is one of the oldest medicinal plants, originating in India and Northern Africa and dating back to ancient Egyptian times (Jensen, 1992).In Pakistan and India, fenugreek is commonly consumed as a condiment (Yoshikawa et al. Fenugreek seeds also lower serum triglycerides, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (Al-Habori and Raman, 1998).
The lipid-lowering effect of fenugreek might also be attributed to its estrogenic constituent, indirectly increasing thyroid hormones (Basch, 2003). The plant protein in fenugreek is 26%, so it might exert a lipid lowering effect (Sharma, 1986). Since a high proportion of diabetic patients in sub-continent suffer from malnutrition, the use of fenugreek which is rich in protein and fiber (48%), has a distinct advantage in these patients (Sharma, 1986). This chapter addresses the effectiveness of fenugreek for lowering hemoglobin (HbA1c) in this randomized controlled trial and determines whether the intervention of taking fenugreek in combination of usual medical care lowers HbA1c in patients with type 2 diabetes.
Effectiveness trials such as this are critical in determining if the interventions are effective in the practical world in which patients live. This randomized control trial addresses the research question “Is Fenugreek treatment with medical care for patients with type 2 diabetes more effective than usual medical care and can it help to lower the haemoglobin in patients with poorly controlled type 2 diabetes”?
Characteristics of type 2 diabetesType 2 diabetes is associated with certain ethnic groups, obesity, family history of diabetes, and physical inactivity, among other factors.
Chronic, untreated hyperglycemia can lead to serious complications that include cardiovascular diseases, blindness, kidney failure, and stroke. Furthermore, very low values of blood glucose (hypoglycemia) for even a short duration can result in loss of consciousness and coma.
The figure 1 shows the complications of type 2 diabetes which is a syndrome characterized by insulin deficiency, insulin resistance, and increased hepatic glucose production. These metabolic abnormalities are treated by use of various medications which are designed to correct one or more of these metabolic abnormalities (Saltiel & Olefsky, 2001). Type 2 diabetes is most common in adults, although younger people are also developing this type of disease. It starts with a slow onset with thirst, frequent urination, weight loss developing over weeks to months. It is also considered to run in families but it may happen with a person without a family history of diabetes as well.
In its early stages, many people with type 2 diabetes can control their blood glucose levels by losing weight, eating properly and exercising. Many may subsequently need oral medication, and some people with type 2 diabetes may eventually need insulin shots to control their diabetes and avoid the disease's serious complications (Saltiel & Olefsky, 2001). Even though there is no cure for diabetes, proper treatment and glucose control enable people with type 2 diabetes to live normal, productive lives.
A major advance for people at risk of developing type 2 diabetes - such as family members of those with the condition - occurred recently when it was shown that diet and exercise can prevent or delay type 2 diabetes. 2004), however, population-based data on the prevalence of diabetic retinopathy in Pakistan and on the visual impairment due to diabetic retinopathy is lacking and only the hospital-based data is available (Kayani et al. Diabetic nephropathy is present in 18% of people diagnosed with diabetes (DSG, 1993) and is a leading cause of end-stage renal disease (Molitch et al.
2003)Stroke: diabetes is associated with a 2- to 4-fold increase in cardiovascular mortality and stroke (Kannel et al.
Therefore, early detection and treatment of diabetes is essential in order to reduce the impact of its serious complications.
Development of type 2 diabetesDevelopment of type 2 diabetes is the result of multifactorial influences that include lifestyle, environment and genetics.
The disease arises when insulin resistance-induced compensatory insulin secretion is exhausted.
A high-caloric diet coupled with a sedentary lifestyle is one of the major contributing factors in the development of the insulin resistance and pancreatic ?-cell dysfunction as shown in Figure 2. However, a predisposing genetic background has long been suspected in playing a contributing role in the development of type 2 diabetes. The metabolic syndrome is defined as a clustering of atherosclerotic cardiovascular disease risk factors that include visceral adiposity (obesity), insulin resistance, low levels of HDLs and a systemic proinflammatory state. There are key components to the metabolic syndrome which include in addition to insulin resistance (the hallmark feature of the syndrome), hypertension, dyslipidemia, chronic inflammation, impaired fibrinolysis, procoagulation and most telling central obesity.3.
Randomized controlled trials with fenugreekThe multiple trials in the past have shown conflicting results of the effect of fenugreek on the patients of type 2 diabetes.
These studies showed some positive results on fasting serum glucose but did not examine hemoglobin (HbA1c) levels. Gupta et al (2001) reported the results of a small randomized, controlled, double-blind trial to evaluate the effects of fenugreek seeds on glycemic control. The authors reported that there were no significant differences between groups in mean glucose tolerance test values at the study's end. However, the trial may have been too small or brief to detect significant mean differences between groups.
Raghuram et al (1994) reported the results of a randomized, controlled, crossover trial of fenugreek seeds in 10 patients with type 2 diabetes. In the fenugreek-treated patients, statistically significant mean improvements were reported for glucose-tolerance test scores and serum-clearance rates of glucose.
Sharma and Raghuram (1990) conducted two randomized, controlled, crossover studies in patients with type 2 diabetes. Significant mean improvements in fasting blood-glucose levels and glucose-tolerance test results were described in the fenugreek-treated patients. Moosa et al (2006) conducted study to evaluate the effect of fenugreek on serum lipid profile in hypercholesteremic type 2 diabetic patients and concluded that fenugreek seeds powder significantly reduced serum total cholesterol, triglyceride and LDL-cholesterol but serum HDL-cholesterol level elevation was not significant. Neeraja and Rajyalakshmi (1996) presented a case series including six men with type 2 diabetes and six without diabetes. The cases suggested fenugreek reduced postprandial hyperglycemia primarily in subjects with diabetes, but less so in subjects without diabetes. The studies conducted to date have been methodologically weak, lacking adequate descriptions of blinding, randomization, baseline patient characteristics, statistical analysis, and standardization data for the therapy used. Demonstrating the efficacy of fenugreek has also been confounded by inconsistencies in the preparations, dosing regimens, and outcome measures used in the trials.
Moreover, none of the investigations have been conducted over the longer period (Basch, 2003).
Method of patient selectionThe patients were recruited from the diabetic medical centre in rural area of Peshawar conducting the study of management of type 2 diabetes among the population aged 30-65 years. Patients having coexisting liver, kidney or thyroid disorder were not included in the study. Diabetes Criteria for patientsThe well known standard screening test for diabetes, the fasting plasma glucose (FPG), is also a component of diagnostic testing. The FPG test and the 75-g oral glucose tolerance test (OGTT) are both suitable tests for diabetes; however, the FPG test is preferred in clinical settings because it is easier and faster to perform, more convenient and acceptable to patients, and less expensive. When it was found necessary, plasma glucose testing was also performed on individuals who have taken food or drink shortly before testing. Such tests are referred to as casual plasma glucose measurements and are given without regard to time of last meal. A confirmatory FPG test or OGTT was also completed on such patients on a different day if the clinical condition of the patient permits.


Laboratory measurement of plasma glucose concentration is performed on venous samples with enzymatic assay techniques, and the above-mentioned values are based on the use of such methods. The A1C test values remain a valuable tool for monitoring glycemia, but it is not currently recommended for the screening or diagnosis of diabetes.
Pencil and paper tests, such as the American Diabetes Association’s risk test, may be useful for educational purposes but do not perform well as stand-alone tests. Capillary blood glucose testing using a reflectance blood glucose meter has also been used but because of the imprecision of this method, it is better used for self-monitoring rather than as a screening tool.
Determination of study sample size The study sample size was determined based on the assumption of the estimation of Standard Deviation (SD).
Therefore, the study design was selected to detect an effect size of 0.5 SD lowering of HbA1c.
It was assumed that 15% patients might be lost to follow-up in control group over the period of three months and only 5 % patients will be lost to follow-up in intervention group.
This assumption was based on the popularity of fenugreek seeds used by diabetic patients in sub-continent to manage their glycemic control. Study population and randomizationInitially 325 patients with type 2 diabetes were invited to pre-randomized interview, out of which only 210 patients were included in the actual trial. Out of the 325 patients, 93 patients did not meet the inclusion criteria and 22 patients refused to participate in the trial. Finally, two hundred and ten (210) patients agreed to participate and signed informed consent documents at the clinic where they used to visit for their usual medical care for diabetes.
Therefore, 102 patients were randomized to intervention group (fenugreek supplements) and 108 to the control group (usual medical care). The randomization code was developed using a computer random number generator in a block size of eight patients. That helped to allocate patients to the intervention and control groups equally in each block – that is each patient would have an equal chance of allocation to either group. Once the randomization phase was completed, all patients were instructed to follow-up the usual medical care for their diabetes for the duration of the 90 days trial.
The patients were allowed to adjust their usual medications as recommended by their doctors. In addition, each patient was asked to go for blood test for HbA1c on day 1 and then return to give blood sample after 90 days.
In addition, participants were advised not to take any other new treatments for the management of type 2 diabetes during the trial periods. The control group in randomized controlled trial received medical care from a physician-coordinated team. This team included physicians, nurses, dietitians, and mental health professionals with expertise and a special interest in diabetes. It is essential in this collaborative and integrated team approach that individuals with diabetes assume an active role in their care. The management plan in that group was based on individualized therapeutic alliance among the patient and family, the physician, and other members of the health care team. This plan has recognized diabetes self-management education as an integral component of care and in developing the plan, consideration was given to the patient’s age, work schedule and conditions, physical activity, eating patterns, social situation and personality, cultural factors, and presence of complications of diabetes or other medical conditions. Patient self-management was emphasized, and the plan emphasized the involvement of the patient in problem-solving as much as possible.
A variety of strategies and techniques were employed to provide adequate education and development of problem-solving skills in the various aspects of diabetes management.
During the implementation of the management plan it was assured that each aspect of diabetes management was understood and agreed on by the patient and the care providers and that the goals and treatment plan were reasonable. Those patients randomized to take fenugreek (intervention group) received 100 gms fenugreek seeds powder from the pharmacy in the clinic. They were instructed to take 50 gms doses twice a day at lunch and dinner time in addition to their normal medications for diabetes.
Those patients randomized to usual medical care (control group) were instructed to take their normal medicines and follow-up with their doctor as per their normal schedule.
All participants were contacted again after 90 days (3-months) to give their blood sample for HbA1c testing. At that time, a questionnaire was sent via e-mail to participants in both intervention and control groups to assess the progress of the fenugreek treatment and clinical care without fenugreek. The clinical and demographic characteristics of the patients in the two groups were well balanced at randomization.
A demographic measure included age, gender, weight, ethnicity, religion, marital status, previous episodes of glycemic control, previous and current treatments of type 2 diabetes. The table 3 gives baseline characteristics of intervention and control groups in RCT trial. Diabetes treatment with medicationsThe treatment options of type 2 diabetes is shown in figure 4 suggesting the specific areas of actions using medications which influence the various organs of the body to correct the metabolic abnormalities such as reducing the liver glucose production, slowing down absorption of sugars from the gut and reducing the insulin resistance. There are currently six distinct classes of hypoglycemic agents available to treat type 2 diabetes. The patients in both the groups in RCT trials received medications recommended by their physicians.
The most common combinations among both the groups were Meglitinide (repaglinide) with Thiazolidendiones and Sulfonylurea with Biguanides. Details of hypoglycaemic medications used in RCT trialThe diabetes medications mentioned in table 4 work in different ways but the main function of all these medications include lowering blood sugar levels; help improve the body’s use of glucose, decrease the symptoms of high blood sugar, help keeping patients with diabetes functioning normally and may prevent the complications, organ-damaging effects and premature deaths diabetes can cause. Since the drugs work in different ways, these are sometimes used in combination to enhance the effectiveness of treatment. In this RCT trial Sulfonylurea was used in combination with Biguanide (metformin) and Meglitinide was used in combination with Thiazolidinedione. The main function of Sulfonylurea is to bind and inhibit the pancreatic ATP-dependent potassium channel that is normally involved in glucose-mediated insulin secretion. Like the sulfonylurea, meglitinide therapy results in significant reduction in fasting glucose as well as HbA1c. The mechanism of action of the meglitinide is initiated by binding to a receptor on the pancreatic ?-cell that is distinct from the receptors for the sulfonylurea.
Metformin is a member of this class and is currently the most widely prescribed insulin-sensitizing drug in current clinical use. Metformin administration does not lead to increased insulin release from the pancreas and as such the risk of hypoglycemia is minimal.
Because the major site of action for metformin is the liver its use can be contraindicated in patients with liver dysfunction.
Thiazolidinedione: The thiazolidinedione (pioglitazone) has proven useful in treating the hyperglycemia associated with insulin-resistance in both type 2 diabetes and non-diabetic conditions. The net effect of the thiazolidinedione is a potentiation of the actions of insulin in liver, adipose tissue and skeletal muscle, increased peripheral glucose disposal and a decrease in glucose output by the liver. Diabetes treatment with diet and exerciseThe normal diabetes treatment addresses the issues related to unhealthy lifestyles, such as lack of physical activity and excessive eating, which are the main causes to initiate and propagate the majority of type 2 diabetes (Michael, 2007). Studies have demonstrated strong relationship between excess weight and the risk of developing type 2 diabetes, hypertension, and hyperlipidemia. Therefore, the objective of physicians is to motivate patients to lose weight and exercise to improve the control of diabetes and slow down or even reverse the natural course of the disease (Michael, 2007).However, it is difficult to overstate the importance of the relationship between lifestyle and the risk of developing type 2 diabetes. There are prospective studies which have demonstrated that lifestyle modification in the form of diet and regular moderate exercise sharply decrease the likelihood of developing type 2 diabetes in high-risk individuals who have impaired glucose tolerance or impaired fasting glucose. The effectiveness of this intervention superseded that of metformin therapy (Knowler et al. In this RCT trial, physicians compiled the flow scheme shown in Figure 5 which represents the method of treatment of type 2 diabetes by the combination of diet, exercise and medication for diabetes monitoring and control. It has been divided into two segments: for obese and normal weight patients and the combination of medication for both the groups of patients.
Dietary consideration for patients (intervention and control group)It has been recommended that carbohydrate and monosaturated fat consumption for the patients with type 2 diabetes should comprise 60-70% of total calories. However, there is some concern that increased unsaturated fat consumption may promote weight gain in obese patients with type 2 diabetes and therefore may cause in reduction of insulin sensitivity (Bantle et al. The “glycemic index” is an attempt to compare the glycemic effects of various foods to a standard, such as white bread.
Although several authors have proposed its clinical usefulness in controlling postprandial hyperglycemia, prospective studies have not demonstrated a clear improvement in hemoglobin (HbA1c) in patients using low-glycemic index diets (Michael, 2007). The physicians in this trial have recommended the best mix of carbohydrate, protein, and fat that was adjusted to meet the metabolic goals and individual preference of the patients with diabetes in both the intervention and control groups. It has been recommended for individuals with diabetes, that the use of the glycemic index and glycemic load may provide a modest additional benefit for glycemic control over that observed when total carbohydrate is considered alone (ADA, 2011).
Monitoring carbohydrate, whether by carbohydrate counting, choices, or experience-based estimation, remain a key strategy in achieving glycemic control.
Physical activity consideration for patients (intervention and control group)Physical activity is a key component of lifestyle modification that can help individuals prevent or control type 2 diabetes.
It is considered that diet is probably more important in the initial phases of weight loss, incorporating exercise as part of a weight loss regimen helps maintain weight and prevent weight regain (Klein et al. In this trial, the message was given to both the groups that as little as 30 minutes of moderate physical activity daily may offer greater benefits to these patients in managing their diabetes.
It has also been reported that in patients with type 2 diabetes, structured regimens of physical activity for 8 weeks or longer improved HbA1c independent of changes in body mass (Sigal et al. The evidence supports the contention that controlling blood glucose through modification of diet and lifestyle should be mainstay of diabetes therapy.
It was found in this RCT that despite being one of the most time-consuming discussions with the patients in both the groups, this is probably the most important patient-physician discussion in regard to diabetes control and prevention of disease progression and complications.
Statistical analysisWe analysed the primary outcome by an un-paired sample t-test (mean difference between baseline and final HbA1c).
The statistical analysis was carried out on an intention to treat basis and that was subject to the availability of data at follow up as well as at entry level for individual patients.
