Why do my readings remain over 200 three hours after a meal, even when I take insulin before eating? I get a feeling of hunger when my levels are over 200.

Dr. William Sullivan


It is not uncommon to have elevated blood glucose 3 hours after meals – even if one takes insulin before the meal. Blood glucose levels after a meal are primarily related to the blood glucose before a meal, the carbohydrate content of the meal, and the effects of insulin or other diabetes medications on preventing a rise in blood glucose levels. The effect of a rapid-acting insulin (Humalog, Novolog, Apidra) is related to the dose of insulin as well as the amount of carbohydrate consumed in the meal. If you are closely following a meal plan as outlined by a dietitian, – then the dose of rapid-acting insulin may need to be increased. Talk with your healthcare provider about how you might be able to adjust your rapid-acting insulin dose to prevent high glucose levels after meals.

you could be eating to many carbs too. that will send your blood glucose thru the roof. so you might want to cut back on those carbs to see if it will help uou
