Question:

What is reactive hypoglycemia and what is its treatment?

Answer:

Reactive hypoglycemia (or postprandial hypoglycemia) means that symptoms of low blood sugar are felt after eating. These symptoms may include feeling tired, shaky, hungry, and anxious. In addition, you may experience sweating, rapid heartbeat and headache. One cause of this condition is thought to be an “over active pancreas” that makes more insulin than the body needs in response to eating a meal. It is also often connected with feelings of anxiety, tension, and emotional upsets (although it’s not clear which causes which). Current thinking states that true hypoglycemia (in non-diabetic individuals) is very rare, so it is a good idea to consult your physician for proper diagnosis and treatment.

According to one source, “reactive hypoglycemia tends to be self-limiting in months or years.” Therefore, the symptoms gradually disappear. Until this occurs, dietary treatment can be helpful. The suggested diet is designed to not “overload” the pancreas and reduce secretion of insulin after eating. To do this, the diet is divided into small, frequent meals and snacks. Each meal or snack generally contains high-protein, low-carbohydrate foods. Sweets, alcohol, and caffeine containing foods are avoided.

If your physician confirms a diagnosis of reactive hypoglycemia, a Registered Dietitian can help by personalizing a diet for you. (To find a Dietitian in your area, try the American Dietetic Association’s Nationwide Nutrition Network at http://www.eatright.org).
