Erythema on the body after drinking may be due to physiological factors such as dilated skin capillaries or allergy to alcohol. It can be relieved by resting and avoiding contact with alcohol.
1. Expansion of skin capillaries: Drinking alcohol will lead to accelerated blood circulation in the body and increased blood flow in the skin, resulting in obvious expansion of capillaries and obvious erythema in some parts of the body. The symptoms of skin erythema can be gradually eliminated through rest.
2. Alcohol allergy: the lack of acetaldehyde converting enzyme in the body leads to skin allergy symptoms. After ethanol is converted into acetaldehyde in the body, the lack of acetaldehyde converting enzyme in the body can no longer be converted into acetic acid to the outside of the body, resulting in acetaldehyde toxicity, which is manifested in various alcohol allergy symptoms, such as itchy whole body after contact with alcohol, the body appears to be red bumps, red spots and so on.
If symptoms of alcohol allergy appear, avoid drinking or contacting any alcohol-containing items.
If the symptoms of red spots on the body worsen after drinking, it is recommended to go to the hospital in time.
