Some diabetic patients usually live in an uncontrolled way and often drink alcohol. When they appear pale, sweating all over, or even drowsy after drinking, beware that it may be a hypoglycemic coma rather than intoxication. Not timely treatment may be life-threatening! Diabetics are extremely prone to hypoglycemia after drinking. The reasons are: 1. Ethanol will increase the blood flow of insulin-secreting islet cells, thus causing a significant increase in insulin secretion, resulting in hypoglycemia after drinking. 2, the elderly body regulation function is poor, when the blood sugar is low can not be timely secretion of blood sugar hormone to fight hypoglycemia, also prone to hypoglycemia. 3, elderly diabetic patients often have neuropathy, combined with heart, liver and kidney insufficiency, so when hypoglycemia occurs, the symptoms are often atypical and may be ignored, which may lead to serious consequences.
