Reactive hypoglycemia is a medical term describing recurrent episodes of symptomatic hypoglycemia occurring 2-4 hours after a high carbohydrate meal (or oral glucose load). 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 and controversial, because a number of stricter or looser definitions have been used, and because many healthy, asymptomatic people can have glucose tolerance test patterns said to be characteristic of reactive hypoglycemia. It has been proposed 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.
Additional recommended knowledge
Although symptoms vary according to individuals' sensitivity to the elevation and decline of glucose levels, some of the more common symptoms are:
There are different kinds of reactive hypoglycemia: 
1) Alimentary Hypoglycemia (consequence of dumping syndrome; it occurs in about 15% of people who have had stomach surgery)
3) Hormonal Hypoglycemia (due to lack of some hormones; i.e., hypothyroidism)
5) Congenital enzyme deficiencies (hereditary fructose intolerance, galactosemia, and leucine sensitivity of childhood)
6) Idiopathic reactive hypoglycemia
7) Late Hypoglycemia (Occult Diabetes; characterized by a delay in early insulin release from pancreatic B cells, resulting in initial exaggeration of hyperglycemia during a glucose tolerance test)
To relieve reactive hypoglycemia, some health professionals recommend taking the following steps:
Postprandial Syndrome and Adrenergic Postprandial Syndrome
If there is no hypoglycemia at the time of the symptoms, this condition is called Postprandial Syndrome. It might be an "Adrenergic Postprandial Syndrome" - the glycemia is normal, but the symptoms are caused through autonomic adrenergic counterregulation. Often, this syndrome is associated with emotional distress and anxious-behaviour of the patient  . Dietary recommendations for reactive hypoglycemia can help to relieve symptoms of postprandial syndrome.
