Type 1 Diabetes Mellitus (T1DM) used to be known as “Insulin Dependent Diabetes Mellitus (IDDM),” a term you will still hear used today. In T1DM, the body’s immune system attacks the cells in the pancreas that produce insulin, known as beta cells. Type 2 Diabetes Mellitus (T2DM) used to be known as “Non-Insulin Dependent Diabetes Mellitus (NIDDM),” a term you will also still hear used today.
What Causes Diabetes The Causes of Diabetes Answering the question of what causes diabetes is not as simple and straightforward as most people think. Diabetes Introduction It is important to begin the section on diabetes by emphasizing just how dangerous the disease truly is.
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or an animal.
If blood sugar levels are either increased or decreased by a greater margin than expected this might indicate a medical condition. Please note that you should perform several consecutive blood glucose tests and not rely on one single measurement. High blood sugar levels affect the arteries throughout the body, especially the organs which have the richest blood circulation: heart, brain, kidney, senses, nerves and other organs. Typical symptoms of high blood sugar levels (diabetes) are thirst, frequent urination and unexpected weight loss.
This blood sugar levels chart is not 100% accurate due to different thresholds set in different countries around the world.

The HbA1c is a measure of the average blood sugar (both high & low levels) over a 3 month period and it is an important indicator of the degree of blood sugar control. It is recommended for people with diabetes to check HbA1c at least 2 times a year & more frequently for those with uncontrolled sugar levels. Although HbA1c measures average blood glucose over the past 3-4 months, more recent glucose levels (recent 4-6 weeks) impact the result more.
Conditions like Anemia, profound blood loss, recent blood transfusion, high triglyceride levels, jaundice, chronic alcoholism etc.

For decades, the diagnosis of diabetes was based on plasma glucose criteria — either the fasting plasma glucose (FPG) or the two-hour value in the 75g oral glucose tolerance test (OGTT). Since last year, the American Diabetes Association has recommended using the A1C test to diagnose diabetes, with a threshold of ?6.5 per cent. NICE recommends metformin as an option for first-line glucose-lowering therapy where blood glucose is inadequately controlled using lifestyle interventions alone. Metformin and the thiazolidinediones (TZDs such as pioglitazone) act on the liver to reduce hepatic glucose production. The glucagon-like peptide-1 (GLP-1) analogues, the inhibitors of dipeptidyl peptidase 4, (DPP-4 inhibitors) and the sulphonylureas are effective in the area of insulin secretion. There are two incretins, known as glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1). Incretins are going to dominate the field of diabetes over the next five years, Prof O’Shea said. The active compound GLP-1 (7-36) is very quickly broken down by DPP-4 into the inactive compound GLP-1 (9-36). Lowering A1C to below or around 7 per cent has been shown to reduce microvascular and neuropathic complications of diabetes and, if implemented soon after the diagnosis of diabetes, is associated with long-term reduction in macrovascular disease. The landmark UKPDS trial of type II diabetes observed a 16 per cent reduction in cardiovascular complications (combined fatal or nonfatal myocardial infarction [MI] and sudden death) in the intensive glycaemic control arm. Aspirin therapy may be considered as a primary prevention strategy in those with type II diabetes who are at increased cardiovascular risk.
Hypertension is a common comorbidity of diabetes, affecting the majority of patients, with prevalence depending on type of diabetes, age, obesity, and ethnicity.


Patients with more severe hypertension (systolic blood pressure ?140 or diastolic blood pressure ?90mmHg) at diagnosis or follow-up should receive pharmacologic therapy in addition to lifestyle therapy. The American Diabetes Association says that treatment should include an angiotensin converting enzyme (ACE) or an angiotensin II receptor blocker (ARB).
Gastric reduction surgery, either gastric banding or procedures that involve bypassing, transposing or resecting sections of the small intestine — when part of a comprehensive team approach — can be an effective weight-loss treatment for severe obesity. Bariatric surgery has been shown to lead to near or complete normalisation of glycaemia in between 55-95 per cent of patients with type II diabetes, depending on the surgical procedure. Patients with type II diabetes who have undergone bariatric surgery need life-long lifestyle support and medical monitoring.
Dr Velma Harkins of the Irish College of General Practitioners, the National Clinical Lead for Diabetes Prof Richard Firth and Dr John Devlin of the Department of Health published guidelines in regard to diagnosis, targets for clinical care and the interventions that are appropriate at each stage of the disease. Metformin is contraindicated in those with renal impairment, those at risk of sudden deterioration of renal function and end-stage cardiac and hepatic failure. DPP-4 inhibitors such as sitagliptin and vildagliptin are approved as add-on therapy to metformin.
Do you agree that private hospitals should be paid via the NTPF to cut public hospital waiting lists? Type 1 Diabetes is almost entirely genetic, whereas Type 2 Diabetes is largely due to poor diet, lack of exercise, and genetic factors. The reason for this name is that people with T1DM are completely dependent on insulin to control their blood sugars.
Once enough of these cells are destroyed, the pancreas can no longer produce enough insulin to maintain blood sugar in the normal range and you become hyperglycemic (high blood sugar). The reason for this name is that people with T2DM are not completely dependent on insulin to control their blood sugars because their bodies still have the ability to produce insulin, usually just less insulin than a regular person. The body naturally tightly regulates blood glucose levels (with the help of insulin that is secreted by pancreas) as a part of metabolic homeostasis. Dramatic changes of blood sugar levels have significant physical symptoms and will increase your risk of diabetes-related complications. The next chart displays all possible blood sugar (glucose) levels along with a short explanation of what the indicators are.
When being tested for diabetes by a impaired fasting glycemia test, blood sugar levels will normally be taken after around eight hours of fasting.
Identify your HbA1c test score, mean blood and glucose level to know if your blood glucose is in the optimum level. In simple terms, it is the amount of sugar (glucose) attached to hemoglobin molecules in the red blood cells.
Thus checking blood sugar level periodically at different times of the day remains equally essential & cannot be replaced by HbA1c checking alone.
She has done her post graduation from Pune University and she is currently pursuing her PhD in area of Diabetes Prevention. However, self blood-glucose monitoring (SBGM) is the single most expensive aspect of diabetes care to the State.
It is no longer necessary to measure glucose to make a diagnosis of diabetes, Prof O’Shea said. Incretins, such as exenatide (Byetta) and liraglutide (Victoza) may be given in type II diabetes. After 10 years of follow-up, the UKPDS showed that for participants originally randomised to intensive glycaemic control — compared with those randomised to conventional glycaemic control — there were long-term reductions in MI (15 per cent with sulfonylurea or insulin as initial pharmacotherapy and 33 per cent with metformin as initial pharmacotherapy).
There is an argument in diabetes about whether blood pressure management, rather than glycaemic management, should be pre-eminent. Multiple drug therapy (two or more agents at maximal doses) is generally required to achieve blood-pressure targets. In this trial, 73 per cent of surgically-treated patients achieved ‘remission’ of their diabetes, compared with 13 per cent of those treated medically.
Long-acting, once-daily sulphonylureas may be useful where concordance with therapy is a suspected problem. Type 1 Diabetes is almost entirely genetic and cannot be controlled by exercise and diet; it must be treated with regular insulin injections.
Beta cell destruction and consequent T1DM can occur at any age; however, it most commonly occurs in adolescents followed by men in their 30s to 40s.


Unlike individuals with T1DM, people with T2DM also have “insulin resistance,” meaning that cells in their bodies do not react to insulin as strongly as they should. Download your blood sugar levels log and keep track of your own blood sugar levels – write down all of your measured values.
An impaired glucose tolerance test involves taking a concentrated amount of glucose and then measuring blood sugar levels after two hours. As the life of a red blood cell is approximately 90 – 120 (3-4 months) days, the HbA1c value predicts average blood sugar of past 3 – 4 months. Both these measurements should support each other helping ensure appropriate blood sugar control for a good quality life.
She works with Diabetes Unit, KEM Hospital (Pune), Just for Hearts (Pune), Moraya Multispeciality Hospital & Healing Hands Clinic (Chinchwad) etc. All of these agents are used and they all confer a benefit to the A1c — and to cardiovascular and microvascular profiles. There were also reductions in all-cause mortality (13 per cent and 27 per cent respectively). In type II diabetes, hypertension usually coexists with other cardiometabolic risk factors.
The UKPDS study proved that if blood pressure could be controlled, patients did much better. This is especially the case if the diabetes or associated co-morbidities are difficult to control with lifestyle and pharmacologic therapy. Am J Med 2009) of studies of bariatric surgery involving 3,188 patients with diabetes reported that 78 per cent had remission of diabetes (normalisation of blood glucose levels in the absence of medications) and that the remission rates were sustained in studies that had follow-up exceeding two years. The Expert Advisory Group in Diabetes in its 2007 report recognised the need for a new model of care for people with type II diabetes. As their ability to produce insulin decreases (which is does progressively over time) and they cannot produce enough insulin to compensate for the insulin resistance of their cells, they become hyperglycemic.
Medical alcohol to clean the skin where you will prick your finger, a sterile tool to prick your finger, some test strips and a glucose meter to read the test strip. Thus, if there is a large amount of sugar circulating in the blood, the HbA1c will be high & vice versa.
Doctors encourage this and need to steer away from it, said Prof Donal O’Shea, Consultant Endocrinologist at St Vincent’s Hospital.
The DPP-IV inhibitors include Januvia (sitagliptin), Onglyza (saxagliptin) and Eucreas — a combination of vildagliptin and metformin. As is the case with microvascular complications, it may be that glycaemic control plays a greater role before macrovascular disease is well developed. Remission rates tend to be lower with procedures that only constrict the stomach, and higher with those that bypass portions of the small intestine. This integration across primary, secondary and tertiary care requires agreed clinical guidelines. Disturbances in the metabolism of blood sugar levels are mainly the consequence of heredity (diabetes in the family), age (over 40), poor diet, excessive body weight (obesity) and physical inactivity. However, compounds have been developed that activate the GLP-1 receptor with a view to improving insulin secretion. Additionally, there is a suggestion that intestinal bypass procedures may have glycaemic effects that are independent of their effects on weight, perhaps involving incretins. People with high blood sugar levels can lower their blood sugar levels by maintaining normal body weight, eating healthy and by physical activity. Blood sugar level (or blood sugar concentration) is the amount of glucose (a source of energy) present in your blood at any given time. Over the time a patient’s condition worsens as body cannot make enough insulin to keep blood glucose at normal levels.
