Hypoglycemia in the elderly

Senile hypoglycaemia refers to a group of syndromes that cause the plasma glucose concentration to be too low for various reasons, excite sympathetic nerves and adrenal medulla, and brain dysfunction. Symptoms are generally considered to occur when blood glucose is below 2.8 mmol / L (50 mg / dl). The elderly are prone to hypoglycemic brain dysfunction. Hypoglycemia is divided into fasting hypoglycemia and postprandial hypoglycemia (ie, reactive hypoglycemia). The former is mostly pathological and the latter is mostly functional.
