Why is my blood glucose high, even while I take medication?

Q: I’m eating three meals and counting my carbs. Yet my blood glucose is high—200’s both in the morning and at bed time. I’m not eating bad carbs nor a lot of carbs. Any suggestions? I’m taking metformin 500 mg bid and Repaglinide 1 mg tid.

Sometimes your carb intake can actually be higher than you think it is, especially if .you're not weighing or tracking your food. Also, although processed carbs in white bread, rice, and sweets raise blood sugar more quickly than whole foods, all carbs raise sugar to some extent. In fact, even modest amounts of whole grains and fruit can raise blood sugar levels quite high in people with diabetes.

Following a low-carb diet with about 30-60 grams of carbs per day may help keep your blood sugar under control during the day. Here is a quick-start guide to following a healthy, sustainable low-carb lifestyle:

Since you take repaglinide three times a day, it's important to speak with your doctor before starting a very-low-carb diet. Repaglinide prompts your pancreas to release insulin, and although your dosage is small and your blood sugars are currently high, cutting back on carbs could potentially lead to low blood sugar in those who take a combination of repaglinide and metformin.
