If a woman drinks alcohol during menstruation, observe whether there is obvious abdominal pain or a significant increase in menstrual flow. During menstruation, the endometrium sheds a lot of blood, resulting in vaginal bleeding, and alcohol will produce a certain degree of stimulation of the female uterus, which may cause abnormal uterine contractions, easily causing obvious abdominal pain or a significant increase in menstrual bleeding. If abdominal pain occurs, you can drink hot water, or use the warm uterus patch, if the abdominal pain is serious, you can take oral non-steroidal anti-inflammatory drugs, if the menstrual flow is obviously increased, you can take Chinese medicines that have the effect of stopping bleeding and regulating menstruation, such as nudiflora zhuzhu tablets, Yunnan red herbs and so on, to reduce the amount of menstruation. If there is no obvious discomfort, no special treatment can be given. During menstruation, alcohol consumption should be avoided to avoid adverse effects on the body, and attention should be paid to diet and menstrual hygiene during menstruation.
