Discuss various statistics regarding diabetes mellitus, including its prevalence in the United States. Differentiate between type 1 and type 2 diabetes, including pathogenesis and prevalence for each type. List and explain the various tests and methodologies used for the identification of diabetes. Discuss various features of hemoglobin A1c and other glycated proteins, including fructosamine and glycoalbumin and their use in the detection of diabetes. Explain long-term monitoring of diabetes mellitus, including the use of estimated average glucose.
Although simply defined on the basis of hyperglycemia, diabetes mellitus today is known to be a highly heterogeneous disease. In the past, the diagnosis of diabetes was based on either fasting plasma glucose or two-hour plasma glucose level in the oral glucose [75 g] tolerance test (OGTT). The glycation of hemoglobin occurs at several amino acid residues and, as a result, several adducts of hemoglobin A (HbA) and various sugars are formed by the nonenzymatic post-translational glycation process. Various methods for the measurement of HbA1c have been described and reviewed.6 These methods can be classified in two major categories. Because of their ability to process a large number of samples and their superior precision, automated HPLC and automated immunoassays are among the most widely used methods. Besides the standardization of various methods, one may also be aware of the clinical situations in which HbA1c may not provide an accurate estimation of glycemic control. Several assays designed to measure glycated serum proteins (fructosamine and GA) have been described. Despite these limitations, measuring fructosamine or GA provides some advantages over measuring glycohemoglobin A1c as they are not affected by RBC life span, and the glycated protein levels respond more quickly to changes in glycemic control than glycohemoglobin A1c. The effective clinical management of diabetes requires accurate measurement and monitoring of blood glucose levels.
Several studies have explored the relationship between HbA1c and chronic glycemia and have supported the association of HbA1c with average glucose levels over the preceding five to 12 weeks.17 These studies have relied on infrequent measures of capillary glucose levels, calling into question the validity of their assessment of chronic glycemia.
Recently, HbA1c has been incorporated into diabetes diagnosis, and is recommended by the International Expert Committee based on advances in instrumentation and standardization that make it an accurate and precise marker. International expert committee report on the role of the A1c assay in the diagnosis of diabetes. Those who have preexisting liver disease and who are on other drugs producing liver damage are at risk for valproate induced liver disease. Need of vitamin c is increased during trauma and surgery for  extra collagen synthesis. It is proposed that high dose of vitamin C intake will increase the anti oxidant property of body.
Absorption of Vitamin C enhances the non-haem iron absorption that is taken at the same time. This A1C chart is based on the DCCT formula, a randomized clinical trial designed to compare intensive and conventional therapies and their relative effects on the development and progression of diabetic complications in patients with type 1.
Recently, the International Expert Committee (2009) and the ADA Clinical Practice Guidelines (just published in 2013) recommended the use of glycated hemoglobin (HbA1c) to diagnose diabetes.2-3 This article will review the current state of the laboratory testing with special focus on the role of  HbA1c and other emerging glycated protein biomarkers, including fructosamine and glycated albumin (GA), in the diagnosis and long-term monitoring of diabetes.
For decades the diagnosis of diabetes mellitus (type 1 and type 2) was made on the basis of an elevated fasting glucose level. Furthermore, in spite of standardization, many factors, including noncompliance for fasting and inability to tolerate the glucose load, among many other factors, influence the final test outcome. Glycemic biomarkers are important tools to monitor glycemic control.5 Measurement of glycated proteins, primarily HbA1c, has been widely used for routine long-term monitoring of glucose control and as a measure of risk for the development of diabetes complications. Hemoglobin A1c was first discovered in 1969 as an abnormal hemoglobin fraction in blood from diabetes patients. This process involves the formation of a labile Schiff base intermediate followed by the Amadori rearrangement. One category is based on separation and detection of HbA1c on the basis of charge differences and includes ion-exchange chromatography, high performance liquid chromatography (HPLC), and agar gel electrophoresis. Glycation of HbA1c not only depends on average glycemia but also on the rate of production or destruction of RBCs.
Like glycohemoglobin, glucose molecules are joined to protein molecules through a nonenzymatic glycation mechanism to form stable ketoamines termed fructosamine. However, these assays are currently used only to complement glycohemoglobin A1c assays to manage diabetic patients when the detection of short-term metabolic changes is required.
Traditionally, plasma glucose has been the lab test used for monitoring the patient with diabetes. More recently, an international multicenter study examined the relationship between average glucose, as assessed with a combination of continuous glucose monitoring and frequent finger-stick capillary glucose testing and HbA1c levels over time, and demonstrated a close relationship between the two. Currently HbA1c is widely used as a glycemic marker for long-term monitoring of diabetes, as it provides valuable information about the degree of glucose control during the previous eight to 12 weeks.

Defining the relationship between plasma glucose and HbA1c in the Diabetes Control and Complications Trial. Cholesterol stones are common in developed countries, whereas pigment stone occur in developing countries. It may be because vitamin C prevent the conversion of nitrites and secondary amines to carcinogenic nitrosamines.. Seven-point capillary blood-glucose profiles (pre-meal, post-meal, and bedtime) obtained in the DCCT were analyzed to define the relationship between HbA1c and BG.
Type 1 diabetes is characterized by absolute insulin deficiency due to autoimmunity leading to ?-cell destruction and can be identified by serological markers of autoimmunity (islet cell autoantibodies). The ADA proposes that fasting plasma glucose (FPG) should be measured in all asymptomatic people ?45 years of age and screening should be considered at a younger age in individuals at increased risk for diabetes.
Based on current recommendations from the National Diabetes Data Group, the OGTT must be done after three days on a diet containing a minimum of 150 g of carbohydrates per day.
The test accurately assesses the mean blood glucose level during the preceding two to three months; therefore, it complements the more traditional measures of glucose control (blood or urine glucose testing). It was later shown that glucose binds to hemoglobin in red blood cells, and the term “glycohemoglobin” is applied to a number of chemically distinct hemoglobin components that are generated when glucose binds to hemoglobin.
The reaction is slow, continuous, and irreversible, and the reaction rate depends on the ambient glucose concentration.
There is no convincing data to show that one method is superior to the other, as practically all commercial methods are standardized to a common reference standard.
Findings from the Diabetes Control and Complication Trial demonstrate that maintaining blood glucose close to normal reduces diabetes complications.17 This study compared the standard versus intensive blood glucose control on the complications of diabetes.
It is also being used as a primary treatment target, as it has been shown to have close association with diabetes complications. However, it should be reiterated that there are some limitations, and HbA1c may not provide accurate information in certain clinical situations that affect RBC life span—for example, certain hemoglobulinopathies (hemoglobin S, C, or E), anemia, and renal dysfunction. If you or someone you know is looking for information on managing GD with real food, I highly recommend it!Gestational diabetes is never part of any mom’s plan .
Converting A1C to equivalent blood-glucose level (as shown by the glucometer) can be easier interpreting the result. He recommends DCCT's formula to convert A1C to BS than the formula by ADAG recommended by ADA. The three-to-five hour oral glucose tolerance test, once the gold standard for diagnosing diabetes, is currently not recommended either by the ADA or the International Expert Committee.2-3 However, both the ADA and International Expert Committee continue to recommend use of the two-hour oral glucose challenge test, especially in gestational diabetes mellitus (GDM).
The clinical utility of insulin measurement is limited, primarily because when fasting glucose is elevated, ?-cell responsiveness decreases, and when the fasting glucose level is normal, late hyperinsulinism may occur in type 2 diabetes or in the early phase of type 1 diabetes. In addition to hemoglobin, other proteins in blood can also be glycated, and glycated proteins such as fructosamine and glycoalbumin (GA) can also be measured and used as an estimation of glucose control.5 Today the use of HbA1c is also recommended by the ADA and other organizations for diabetes screening and diagnosis.
Minor components of HbA were first recognized because of the differences in their electrical charges and were called “fast hemoglobin” as they migrated at a faster rate than an entire HbA molecule when placed in an electrical field. Albumin is the most abundant serum protein, and it contains multiple lysine residues, all of which can be glycated.
There are clinical situations in which fructosamine or GA should not be used, such as for thyroid disease (as in thyrotoxic or hypothyroid patients in whom protein turnover is increased or decreased). Now HbA1c levels can be expressed and reported as eAG for most patients with type 1 or type 2 diabetes.
Furthermore, its value can be translated into eAG values, providing valuable information to clinicians in monitoring patients with diabetes. If a discrepancy between blood glucose and HbA1c is observed, one must consider the measurement of extracellular glycated proteins (fructosamine or GA), as these are not affected by RBC life span or iron status.

Today, diabetes-associated complications remain the leading cause of heart disease- or stroke-related deaths and are associated with long-term damage including the failure of organs such as eyes and kidneys. Type 2 diabetes is caused by insulin resistance and lack of compensatory insulin secretory response. However, it has some limitations, indicating the need for the use of other glycated protein biomarkers. Also, HbA1c levels can be false high in situations that increase the production of RBCs, as in patients with chronic kidney disease who receive erythropoietin for anemia or in patients who receive a blood transfusion.11 In brief, HbA1c levels are shown to be positively associated with hemoglobin levels and are negatively associated with erythropoietin dose. Levels are also influenced by low albumin levels, as seen in patients with protein-losing enteropathy, nephritic syndrome, or liver failure.
Today, use of HbA1c is accepted as a long-term monitoring tool for the management of diabetic patients and is used in conjunction with plasma or finger-stick glucose testing. The calculated eAG level gives healthcare providers a more useful index of chronic glycemia.
However, their relationship to average glucose and their prognostic value to diabetes complications are not clear, as in the case of HbA1c. In contrast to type 1 diabetes, type 2 diabetes is highly prevalent and accounts for 90% to 95% of all diabetes cases.
The most important HbA component in diabetes is HbA1c, which has glucose attached at the N-terminal-amino groups of both ? chains of hemoglobin.
Just like glycohemoglobin, fructosamine and GA measurements serve as an index of the mean concentration of glucose in the blood during the preceding several weeks.
Portable glucose meters are routinely used either in physician offices or by patients at home.
Yet there are many misconceptions about this diagnosis, both in conventional health care and the integrative medicine world.
However, because of rapid turnover of serum proteins compared to hemoglobin, the fructosamine and GA levels reflect glucose control over a shorter period of two to three weeks rather than six to 10 weeks for glycohemoglobin. The current recommendation, therefore, is to normalize fructosamine results to a given serum albumin or total protein concentration. Day-to-day management as guided by self-monitoring of blood glucose by patients with the use of glucose meters is a common practice today.


Also, with a colorimetric analysis, bilirubin, hemolysis, and lipemia will likely interfere in the measurement. Ia€™ll also be sharing why the typicalA gestational diabetes diet fails and why a real food, nutrient-dense, lower carbohydrate approach is ideal for managing gestational diabetes.What is Gestational Diabetes?Gestational diabetes is usually defined as diabetes that develops or is first diagnosed during pregnancy.
However, it can also be defined as a€?insulin resistancea€? or a€?carbohydrate intolerancea€? during pregnancy.I prefer to rely on the latter description because, at the end of the day, gestational diabetes is the result of insulin resistance, which means a woman is unable to tolerate large amounts of carbohydrates without experiencing high blood sugar. However, in our modern world where food is rarely scarce and refined carbohydrates are everywhere, this adaptation can work against us.
This is especially true if a woman already has some level of insulin resistance before becoming pregnant, which is becoming more common.[2]Why Early Screening for Gestational Diabetes is HelpfulIn years past, it was thought that the elevated blood sugar levels seen with gestational diabetes only begin to occur in the second and third trimester, when placental hormones are at their peak and insulin resistance spikes. This is why gestational diabetes is classically screened for around 24-28 weeks of pregnancy.However, researchers have now found that gestational diabetes can be predicted earlier, by relying on a blood test called hemoglobin A1c (for short, A1c). As their pregnancies progressed, their insulin resistance got more severe, as a natural result of placental hormones and weight gain, resulting in elevated blood sugar.Moreover, gestational diabetes is increasingly believed to be an early indicator for the later development of diabetes, which means a womana€™s insulin resistance continues or worsens years after they give birth. Women who have gestational diabetes have a 7-fold higher risk of developing type 2 diabetes later in life.[4]Can Gestational Diabetes be Prevented?Not all women with gestational diabetes have preexisting issues with glucose tolerance or insulin resistance, but research does show that wise preconception practices may prevent some cases of gestational diabetes.
For women with a body mass index (BMI) greater than 35, the risk of gestational diabetes is five times greater than a woman at a healthy weight, most likely because insulin resistance tends to go up at higher body weight.[8]Vitamin D deficiency has also been associated with gestational diabetes (and, not surprisingly, insulin resistance). When those two arena€™t enough to bring the blood sugar levels down to normal, a woman may need insulin or medication.Many women would rather make dietary changes to control their gestational diabetes, than jump right to medicine (and most doctors feel the same way).
Often, much to their disappointment, my patients had to start medication or insulin in order to control their blood sugar.
Carbohydrates are the primary macronutrient that raises the blood sugar, so why are we suggesting they eat lots of carbohydrates?The primary reason clinicians are afraid to endorse a lower carbohydrate diet for pregnancy is that theya€™ve been given outdated information regarding ketosis.
This topic is so complex that I devote an entire chapter to in my book,A Real Food for Gestational Diabetes. But the short answer is that low-level nutritional ketosis is common during pregnancy, does not carry the same risks as starvation ketosis or diabetic ketoacidosis, and does not negatively impact the brain development of a baby.[19]What Level of Carbohydrates is Best?There will likely always be controversy around the ideal level of carbohydrates a woman should consume during pregnancy and frankly, I believe it will vary woman-to-woman based on her blood sugar control. But, in general, I find most women with gestational diabetes benefit from a diet that has less than 175g of carbohydrates per day.My approach is to have a woman monitor her blood sugar while eating her usual diet (using a home glucose monitor) to get a baseline of how food affects her blood sugar.
Below are some simple tips you can implement.Request getting your HbA1c (hemoglobin A1c) measured with your first trimester labs to get a better idea of your baseline blood sugar control. That way, you can take action earlier in your pregnancy if you need to.Ask to have your vitamin D levels measured (25-hydroxy vitamin D), so you can correct deficiency if ita€™s present. Depending on where you live, time of year, and time spent outdoors in sunlight, you may need to add a vitamin D supplement to meet target levels.[22]If you have gestational diabetes, monitor your blood sugar in the morning (fasting) and after each meal to learn your bodya€™s unique pattern and response to different foods (and combinations of food). Adjust your diet and exercise levels accordingly, knowing that carbohydrates tend to raise your blood sugar the most, fat and protein tend to stabilize your blood sugar, and exercise tends to lower your blood sugar.Emphasize foods with plenty of fat and protein, both of which stabilize, rather than directly raise, the blood sugar. Pasture-raised meat (including organ meat), poultry, eggs, wild-caught fish, full-fat cheese, heavy cream, nuts, seeds, avocados, olives, butter, and some coconut products fit into this category.Embrace low-glycemic sources of carbohydrates, like non-starchy vegetables (lots of these!), nuts, seeds, and low-sugar fruit (like berries). For example, ita€™s better for your blood sugar levels to have a servings of sweet potatoes alongside grass-fed beef, sauteed spinach, and butter rather than by itself.Avoid large portions of carbohydrates at one time to prevent blood sugar spikes.
Ita€™s far better to have fruit as a snack twice per day than to have a large fruit salad in one sitting.Exercise regularly. A real food approach is ideal for gestational diabetes, because it emphasizes nutrient-dense foods that provide a baby with all the critical nutrients for growth, while also minimizing blood sugar spikes.Knowledge is power.
2Real Food On A Budget Pregnancy 10 Comments About Lily Nichols, RDN, CDE, CLTLily Nichols, RDN, CDE, CLT is one of the countrya€™s most sought after a€?real food for pregnancya€™ experts whose approach to nutrition embraces real food, integrative medicine, and mindful eating.She is a regular speaker at medical conferences on gestational diabetes and prenatal nutrition. I had gestational diabetes during my pregnancy and it was one of the most frustrating and depressing seasons of my life.
I had no traditional risk factors other than maternal age over 30, although since then I’ve done a lot of research and discovered there is a link between autoimmune disease and gestational diabetes. I could talk on and on about my experience, what I learned, what I will do differently next time, etc (supplements, exercise, diet). I felt like the focus was on birthing a baby of a certain size rather than on our day-to-day health and well-being. In the end my son was born healthy at 39 weeks with barely any sign that his mom had gestational diabetes.
Our great frustration is that he is now allergic to all the foods I was required to eat in large quantities for that diet- dairy, eggs, chicken, blueberries. Brewer’s Pregnancy Diet is an excellent resource that eliminates many pregnancy complications.
The whole diagnosis of gestational diabetes can be a real pain to deal with without the right kind of help. Protein, vegetables, a little fruit (low on the glycemic index), higher fat dairy…Thanks for this post! Instead of hearing snarky comments like, “You do know that *half* a banana is one serving, right?” Yeah, maybe not eating bananas at all would have been easier! I have been gluten free for several years and I feel that I should have been gluten free when I was pregnant.
My fasting levels are checked every year or so because of my high risk of developing Type 2 diabetes.
I was able to get my blood sugars under tight control basically how you suggested- monitoring and adjusting my diet accordingly. I’m so nauseous and all I can tolerate (barely) is crackers, bread, rice, and watered down juice or broth. On the other hand, I think I am actually glad I was diagnosed with GD, because it certainly gave me a huge kick in the butt down the path of healthy living, good nutrition, and label reading!
