reactive hypoglycemia

reactive hypoglycemia,

low levels of glucose in the circulating blood (45 to 50 mg/dL) in an arterialized specimen after ingestion of carbohydrates by patients who have had stomach surgery, causing food to travel quickly into the intestine.

hypoglycemia (hī´pōglīsē´mē),

n a condition existing when the concentration of blood sugar (true blood sugar) is 40 mg/100 ml or less. Symptoms may not occur even when the concentration is considerably less. Symptoms include nervousness, hunger, weakness, vertigo, and faintness. Hypoglycemia may occur in the fasting state or following the injection of insulin.

hypoglycemia, fasting,

n a type occurring in the postabsorptive state; occurs in renal glycosuria, lactation, hepatic disease, and in central nervous system lesions.

hypoglycemia, insulin,

n a type resulting from improper administration of insulin. If hypoglycemia is severe, convulsions, coma, and death may occur. See also shock, insulin.

hypoglycemia, mixed,

n a type occurring during the fasting state and after the ingestion of carbohydrates; occurs in idiopathic spontaneous hypoglycemia of infancy, in anterior pituitary and adrenocortical insufficiency, and with tumors of the islet cells of the pancreas.

hypoglycemia, reactive,

n a type occurring after the ingestion of carbohydrates with an excessive release of insulin, as in functional hyperinsulinism.

hypoglycemia, spontaneous,

n a type that is functional (such as in renal glycosuria, lactation, and severe muscular exertion) or is caused by organic disease such as in hepatic disease and adrenocortical insufficiency.

reactive hypoglycemia

 Plasma glucose measuring < 2.8 mmol/L–US: < 50 mg/dl with Sx of adrenergic neural activation–eg, weakness, palpitations, tremor, sweating and hunger, occurring after a meal or after oral glucose loading, caused by compensatory insulin hypersecretion
