Reactive hypoglycemia, or postprandial hypoglycemia, is a medical term describing recurrent episodes of symptomatic hypoglycemia occurring within 4 hours after a high carbohydrate meal (or oral glucose load) in people who do not have diabetes. It is thought to represent a consequence of excessive insulin release triggered by the carbohydrate meal but continuing past the digestion and disposal of the glucose derived from the meal.
The prevalence of this condition is difficult to ascertain because a number of stricter or looser definitions have been used. It is recommended that the term reactive hypoglycemia be reserved for the pattern of postprandial hypoglycemia which meets the Whipple criteria (symptoms correspond to measurably low glucose and are relieved by raising the glucose), and that the term idiopathic postprandial syndrome be used for similar patterns of symptoms where abnormally low glucose levels at the time of symptoms cannot be documented.
For diagnosis, a doctor can administer an HbA1c test to measure the blood sugar average over the past 2-3 months. Additionally, a 6-hour glucose tolerance test will chart blood sugar during the past six hours.
According to the U.S. National Institute of Health (NIH), a blood glucose level below 70mg/dL at the time of symptoms followed by relief after eating confirms a diagnosis for reactive hypoglycemia.
