Women should not drink beer during the onset of menstruation. Drinking beer can cause indigestion in the gastrointestinal tract and promote blood circulation in the pelvic cavity, increasing menstrual blood flow and blood clots, and can also lead to nervous system excitement, causing insomnia and fatigue in women, which is not good for women’s health. During the menstrual period, women should pay attention to proper rest, do not eat cold, spicy, stimulating food, and alcohol should not be taken. Eat more easily digestible, blood-supplementing foods as appropriate to facilitate the normal discharge of menstrual blood, as well as to help the body recover. Menstruation is a normal physiological cycle of the female body, due to the decline in the level of hormones secreted by the ovaries, there is often a decrease in appetite, so women must pay attention to the occurrence of adverse conditions.
