Hypoglycemia is a disease that blood glucose (referred to as blood sugar) levels lower than normal concentrations, increased sympathetic excitation appears, brain dysfunction, which led to hunger, palpitations, sweating, symptoms of mental disorders. In general the concentration of plasma glucose <2.8mmol / L, or whole blood glucose <2.5mmol / L for low blood sugar. Cause of multiple, complex pathogenesis. Adult blood glucose less than 2.8mmol / L (50mg / dl) may think are too low blood sugar, but clinical symptoms appear, the larger individual differences.
According to the etiology and pathogenesis can be divided into two categories, namely, spontaneous hypoglycemia and hypoglycemia exogenous. Was divided into spontaneous hypoglycemia: hunger, sex (fasting) and reactive hypoglycemia (postprandial) hypoglycemia, hypoglycemia in the exogenous use of oral hypoglycemic agents or insulin in patients with excessive levels of diabetes.
Hypoglycemia is not an independent disease, but because of some pathological and physiological reasons why low blood sugar physiological limit to the following. Early identification of the disease, prompt treatment is important, can be cured. Serious and long-term hypoglycemia can be caused by a wide range of central nervous system damage, resulting in irreversible neuropathy, or even death.
