The term postprandial hypoglycemia ( latin post , 'lat and. After prandium , meal' and Greek  ὑπό hypo under 'and Greek. Γλυκύς glykys , sweet' and Greek. Αἷμα haima , blood ') (formerly known as reactive or functional hypoglycemia designated ) describes a sharp drop in blood sugar levels a few hours after consuming a meal that is mainly composed of short-chain carbohydrates . The common terms are digestive sleep and the colloquial terms soup , schnitzel or eating coma .


The development of postprandial hypoglycemia can be caused by various disorders, for example:


The symptoms correspond to the neurological abnormalities that are generally typical of hypoglycaemic conditions .

This must be distinguished from adrenergic postprandial syndrome (APS), in which a violent sympathetic "counter-regulation" takes place before the blood sugar level drops, which can manifest itself in the form of sweating, tremors, palpitations, anxiety and nausea. It is still unclear what causes this disorder of the autonomic nervous system .

An adrenergic symptoms similar nature can also be found at the dumping syndrome , which also carried fullness and fullness, nausea, rumbling in the upper abdomen and blood pressure disorders associated with tachycardia or bradycardia distinguished. There are two different forms:

  • the early dumping syndrome (also known as jejunal hyperosmolar syndrome ), which occurs in 10–15% of cases after resecting stomach operations , in which these osmotically large quantities of water in the small intestine bind within 30 minutes of ingesting highly concentrated carbohydrates
  • and late dumping syndrome , which leads to simple postprandial hypoglycemia.
