It is suggested that comprehensive examination and combination of traditional Chinese and western medicine can achieve faster results. The pain mainly comes from menstrual cramps, which is the most severe on the first day and lasts 1 to 2 days. At the same time, nausea, vomiting, dizziness and fatigue may occur. There are many factors that cause dysmenorrhea, and the common ones are: 1) Cervical canal stenosis: menstrual outflow is mainly blocked, causing dysmenorrhea; 2) Uterine dysplasia: Uterine dysplasia is easy to be complicated with abnormal blood supply, leading to uterine ischemia and dysmenorrhea; 3) Abnormal uterine position: If the female uterus position is extremely backward or forward, it can affect the smooth menstrual blood and cause dysmenorrhea; 4) Mental and neurological factors: Some women are too sensitive to pain. 5) Genetic factors; 6) Endocrine factors: menstrual abdominal pain is related to the increase of progesterone in luteal phase; Increased content of prostaglandin (PG) in endometrium and menstrual blood: PGE2 can act on contraction of uterine muscle fibers, causing dysmenorrhea. The content of prostaglandin in endometrial tissue of dysmenorrhea patients was significantly higher than that of normal women. 7) Excessive uterine contraction: Although the uterine contraction pressure of dysmenorrhea patients is basically the same as that of normal women (the normal pressure is about 4.9Kpa), the duration of uterine contraction is long and it is often difficult to relax completely, so dysmenorrhea caused by excessive uterine contraction occurs. Premarital dysmenorrhea will disappear naturally after giving birth after marriage, especially dysmenorrhea caused by cervical canal stenosis and abnormal uterine position, which can disappear or be relieved after natural delivery. There are many reasons for less menstrual flow, including weakness, illness, blood loss, spleen fatigue, frequent kidney damage during sexual intercourse, blockage of meridians, and poor blood circulation. But in general, it is caused by the following reasons: (1) Excessive dieting is a career for women, but some girls will use the most rude excessive dieting method to lose weight for the sake of "devil figure". Women's menstruation has a great relationship with weight and body fat content. Girls who already have menstrual problems should stop losing weight, strengthen nutrition and restore health. (2) Excessive work and rest, endocrine disorders, too fast pace of life, increased work pressure, long-term mental stress, physical fatigue, excessive work and rest, etc. It is easy to cause endocrine disorders, resulting in too little menstrual flow. Therefore, sisters should learn to adjust the pace of life and keep a good routine in a tense life. (3) Psychological depression and sulking. From the perspective of traditional Chinese medicine, sulking easily leads to liver depression and qi stagnation, thus reducing menstrual flow. In addition, excessive mental stimulation, tension and psychological trauma can also cause oligomenorrhea. (4) After induced abortion, the ovulation function of the ovary can generally be restored within 22 days, and menstrual cramps occur about 1 month. However, a few women have prolonged menstrual period, different menstrual periods and amenorrhea after induced abortion, and generally return to normal after 2-3 months. (5) Decreased ovarian function directly affects women's menstruation. In the late menstrual period, the amount of menstruation is less. Modern medicine thinks that it is related to follicular dysplasia or anovulation. Therefore, promoting ovulation and enhancing ovarian function are the main links in the treatment of oligomenorrhea. (6) Chest lesions Many women will have premenstrual breast pain but less menstrual flow, and symptoms such as breast pain may be liver depression and qi stagnation. It is necessary to soothe the liver and regulate qi, open the blood vessels and achieve the overall effect of regulating menstruation. Five Harms of Less Menstruation (1) When the amount of menstruation is less, endometrial displacement, cervicitis, menstrual arthritis, menstrual eruption, menstrual toothache and menstrual asthma may occur. (2) Less menstrual flow will also cause acne, which will affect the beauty of women's faces, and these spots can not be solved by cosmetics alone. (3) Less menstrual flow can cause headaches and even infertility in severe cases. (4) Less menstrual flow caused by gynecological diseases will also affect women's fertility. (5) If the amount of menstruation is small or the quality of menstruation is not good, there will not be enough menstrual blood and high-quality nutrients for the normal growth and development of the baby after pregnancy.
