In medicine, there is no such thing as discharging bruises during menstruation, menstrual blood can be discharged by itself, and a normal diet during menstruation will be fine; if the menstrual period is too long or there is too much or too little menstrual blood, an early examination should be conducted to rule out pathological factors, and treatment such as medication or surgery can be taken if necessary. Menstruation is regular and self-limiting, the average menstrual cycle lasts about 28 days, and the menstrual period usually lasts 2-8 days without any special intervention, and the endometrium can be completely stripped and repaired in a week or so, and the menstrual bleeding can stop. Therefore, healthy women generally do not need to take measures such as dietary therapy to promote the discharge of menstrual blood during menstruation. Some women have prolonged menstruation for more than 8 days, which is mostly caused by pathological factors, such as uterine fibroids, endocrine disorders, etc. They should check ultrasound, hormone levels, etc. in time to clarify the cause of the disease, and according to the cause of the disease, take surgical treatment, or take medication combining estrogen tablets, progesterone capsules and other drugs to treat the disease.
