Myo-inositol or 1D-chiro-inositol withdrawal can cause temporary reactive hypoglycemia.There are several kinds of reactive hypoglycemia:
Alimentary hypoglycemia (consequence of dumping syndrome; it occurs in about 15% of people who have had stomach surgery)
Hormonal hypoglycemia (e.g., hypothyroidism)
Helicobacter pylori-induced gastritis (some reports suggest this bacteria may contribute to the occurrence of reactive hypoglycemia)
Congenital enzyme deficiencies (hereditary fructose intolerance, galactosemia, and leucine sensitivity of childhood)
Late hypoglycemia (occult diabetes; characterized by a delay in early insulin release from pancreatic beta-cells, resulting in initial exaggeration of hyperglycemia during a glucose tolerance test)"Idiopathic reactive hypoglycemia" is a term no longer used because researchers now know the underlying causes of reactive hypoglycemia and have the tools to perform the diagnosis and the pathophysiological data explaining the mechanisms.To check if there is real hypoglycemia when symptoms occur, neither an oral glucose tolerance test nor a breakfast test is effective; instead, a hyperglucidic breakfast test or ambulatory glucose testing is the current standard.The body requires a relatively constant input of glucose, a sugar produced upon digestion of carbohydrates, for normal functioning. Glucagon and insulin are among the hormones that ensure a normal range of glucose in the human body. Upon consumption of a meal, blood sugar normally rises, which triggers pancreatic cells to produce insulin. This hormone initiates the absorption of the just-digested blood glucose as glycogen into the liver for metabolism or storage, thereby lowering glucose levels in the blood. In contrast, the hormone glucagon is released by the pancreas as a response to lower than normal blood sugar levels.
Suggestions include sugary foods that are quickly digested, such as:

Dried fruit
Soft drinks
Juice
Sugar as sweets, tablets or cubes.The anti-hypertensive class of medication known as calcium channel blockers could be useful for reactive hypoglycemia as inhibition of the calcium channels on beta islet cells can help prevent an overproduction of insulin after a meal is eaten. Postprandial syndrome
If there is no hypoglycemia at the time of the symptoms, this condition is called idiopathic postprandial syndrome. It might be an "adrenergic postprandial syndrome" — blood glucose levels are normal, but the symptoms are caused through autonomic adrenergic counterregulation. Often, this syndrome is associated with emotional distress and anxious behaviour of the patient. This is often seen in dysautonomic disorders as well. Dietary recommendations for reactive hypoglycemia can help to relieve symptoms of postprandial syndrome. See also
