Menstruation is a barometer of women's health, and analyzing it can sometimes help determine a woman's physical and mental health. Due to the unique physiological characteristics of women, theoretically every woman may experience menstrual abnormalities throughout their lifetime. In response, Professor Xu Hong, Vice President of the International Peace Maternal and Child Health Center affiliated with Shanghai Jiao Tong University School of Medicine, stated that if there are abnormalities in menstruation, it indicates that a woman's body may have organic reproductive diseases, or there may be problems related to the endocrine and ovulation system. Female friends must pay attention to it. Professor Xu Hong introduced that there are several key points to determine whether a woman's menstrual cycle is normal. The first is the menstrual cycle, which refers to the number of days between the first day of two adjacent menstrual cycles. The normal menstrual cycle for women is usually around 21-35 days; The second is the menstrual period, which falls within the normal range of 2 to 7 days; The third is the regularity of menstruation; The fourth is the amount of bleeding during menstruation, which ranges from 5 milliliters to 80 milliliters in a normal menstrual period. If any of the above aspects are abnormal, female friends should pay more attention. There are many reasons for menstrual abnormalities. Part of it is determined by the specific physiological characteristics of women, such as changes in hormone levels during puberty and menopause, which are the triggers for menstrual abnormalities during that period. In addition, various factors such as taking weight loss pills and emergency birth control pills, poor lifestyle habits, excessive fatigue, mental stress, life stress overload, and excessive intake of raw and cold foods may also be the triggers for menstrual abnormalities. Various diseases such as endometrial lesions, polycystic ovary syndrome, ovarian tumors, pituitary tumors, thyroid dysfunction, anemia, etc. may also lead to menstrual abnormalities. Professor Xu Hong pointed out that if organic and structural lesions are excluded, adjusting lifestyle is the first choice for women to correct menstrual abnormalities. Exercise, dietary adjustment, psychological counseling, and other methods can help intervene in menstrual abnormalities. If patients experience anovulatory bleeding or ovulatory bleeding, medication intervention is generally used. Professor Xu Hong stated that the treatment plans for intermittent bleeding such as anovulatory bleeding or ovulatory bleeding vary depending on individual circumstances. Drug interventions are divided into two categories: traditional Chinese medicine and Western medicine, among which Western medicine includes compound oral contraceptives, progesterone replacement therapy, and ovulation promoting therapy. For example, low doses of estrogen and progesterone, also known as compound oral contraceptives, can alleviate excessive menstrual flow caused by menstrual abnormalities in specific situations. Professor Xu Hong reminds that every woman should take care of their own health. In terms of menstruation, monthly data records can be kept to have a more intuitive and comprehensive understanding of their health status. If any adverse signals are detected, it is important to seek the help and treatment of a professional doctor as soon as possible. (Ling Su)
