Usually, when you are having your period, you are not allowed to drink alcohol during your menstrual period. During menstruation, the body’s resistance is often low and metabolism is slowed down. If you drink alcohol at this time, it will easily lead to the accumulation of alcohol in the body, which will slow down the metabolism of the liver, and may cause nausea, vomiting, headache, dizziness and other uncomfortable symptoms, and in severe cases, it will easily cause alcohol poisoning. Alcohol can also increase the permeability of blood vessels, increasing menstrual flow and causing prolonged periods as well as heavy menstrual flow. During menstruation, you need to pay attention to keep warm, reasonable rest, eat a light diet, and if you feel unwell, you need to consult a doctor in time.
