Endocrinology (including Diabetes)/COMPETENT ADVICE


I am in need of your competent advice,now a days I am taking METFORMIN 500 mg twice daily but feels that the values of my post Prandial sugar are high as per criteria of American diabetes association i.e post meal sugar should be less than 180 mg/dl. My fasting and Post Prandial blood glucose levels are as follows on different occasions from November 2012 to date. 111/196, 111/197, 116/185,117/154, 125/196,128/199.,127/203 mg/dl.  Could I add antidiabetic medicines from other classes like Sulfonylureas; Alpha-glucosidase inhibitors; Meglitinides alongwith metformin to control post meal values?.If so; than which class of drug would be effective in my Case,please.Awaiting for your early reply,please.

  Let me start by saying that I am not a medical doctor and, therefore, am not able to prescribe or recommend diabetes medications.  Having said that, I can tell you what I would do in your case.  I would not start by adding in more medications; rather, I would see what I could adjust in my lifestyle (food, exercise, stress levels, sleep, etc.) that can help lower my body's insulin resistance and, accordingly, insulin needs.  One easy thing to address is the quantity and quality of carbohydrates in your diet.  Since your postprandial glucose levels are running high, you would likely benefit greatly by cutting back on your carbohydrate intake (particularly refined or processed carbs) since those have the most immediate impact on PP glucose levels.  Also, adding in more physical movement/exercise to your day can lower your blood glucose responses all day long.  If I were to add in other medications, I would wait to see the effects of my lifestyle changes first before deciding.  I have a lot of helpful articles about lifestyle changes on my web site and blog, which you can find online at www.shericolberg.com.  Hope this help.  Sheri

Sheri Colberg, PhD


I am an exercise physiologist with a PhD who specializes in diabetes--as such I CANNOT answer general questions about other endocrine problems as I am neither an expert in all areas of endocrinology nor am I a medical doctor. My expertise lies in answering questions about diabetes (of any type) and physical activity, so please limit your questions to those areas. I can help you if you want to begin exercise or if you're already a diabetic athlete, and I am prepared to respond to questions about physical activity to which even your diabetologist may not know the answer. I can give suggestions about changes in your diabetic medications that differing types and intensities of exercise may necessitate, but I will have to refer you to your regular health care team to get final approval to make such changes. I can also answer questions about physical fitness, exercise metabolism, prediabetes reversal, and prevention of type 2 diabetes and diabetic complications.


I have both personal and professional experience in the areas of diabetes and exercise/physical activity. On a personal level, I have had type 1 diabetes since 1968, and I have been an avid exerciser since I was a child. Professionally, I have been conducting clinical studies on diabetes and exercise since 1992, largely with funding from the American Diabetes Association. I am also the author of 8 books related to diabetes, exercise, and more: The Diabetic Athlete (2001), Diabetes-Free Kids (2005), The 7 Step Diabetes Fitness Plan (2006), 50 Secrets of the Longest Living People with Diabetes (2007), The Science of Staying Young (2007), Matt Hoover's Guide to Life, Love, and Losing Weight (2008), Diabetic Athlete's Handbook (2009), and Diabetes? No Problema! (2009).

I am a Fellow of the American College of Sports Medicine, a professional member of the American Diabetes Association (and professional volunteer for the ADA), and a former member of the Board of Directors of the Diabetes Exercise & Sports Association.

I have published research and review articles in the following journals and magazines: Diabetes Care, Diabetes, Journal of Diabetes & Its Complications, Diabetes Self-Management, Medicine & Science in Sports & Exercise, Journal of Applied Physiology, The Physician and Sportsmedicine, Journal of Clinical Investigation, International Journal of Obesity, FASEB Journal, The Diabetes Educator, Journal of Physical Education, Recreation, and Dance, Clinical Exercise Physiology, Clinical Diabetes Reviews, Insulin, ACSM's Health & Fitness Journal, Biomechanics, On the Cutting Edge, Diabetes Technology & Therapeutics, Microvascular Research, Drug Benefit Trends, ACSM Certified News, Diabetes Health, SportEX Health, Diabetes Focus, Diabetes In Control, dLife-For Your Diabetes Life, Pediatrics for Parents, and My TCOYD (Taking Control of Your Diabetes) Newsletter. I have also been interviewed in myriad other magazines, such as Men's Health, Men's Fitness, Diabetes Forecast, Countdown Magazine, Joe Weider's Muscle & Fitness, Health, Tidewater Parent, Barron's News, Diabetes New Day, and Newsweek International.

I have an undergraduate degree (1985) from Stanford University, a Master's degree in exercise physiology (1987) from the University of California, Davis, and a Ph.D. (1992) from the University of California, Berkeley, in the same field. I also spent two years in an NIH-funded postdoctoral research position in endocrinology (studying obesity, diabetes, metabolism, and exercise) at the University of Pittsburgh School of Medicine (1993-1994).
