The phenomenon of sweating in the toilet after drinking alcohol may be related to physiological metabolism, hypoglycemia and postural hypotension. 1. Physiological metabolism: Alcohol has the effect of dilating blood vessels and accelerating blood circulation, which may increase the body’s metabolism and cause an increase in sweat secretion after drinking alcohol. 2. Hypoglycemic reaction: If you eat too little while drinking, the metabolism of alcohol will consume the glucose in the body, which may induce hypoglycemic reaction, which will be manifested as cold sweating, tightness in the chest, palpitation and dizziness. 3. Postural hypotension: Drinking alcohol may lead to abnormal regulation of blood pressure, in the process of going to the toilet, due to changes in body position induced postural hypotension, which will be manifested in the clinic as dizziness, blurred vision and cold sweat. If sweating persists after drinking alcohol, it is recommended to consult a hospital promptly.
