Women who don't come to menstruation for a long time may have the following hazards: 1, the patient's uterus will shrink, and the female reproductive tract will also shrink. It is more difficult to promote menstrual cramps after atrophy, and even after atrophy, patients may have difficulty or pain in the same room. 2, the patient does not come to menstruation for a long time, if not actively treated, it will affect the patient's reproductive function, such as amenorrhea caused by endometrial adhesion. If the adhesion is not treated in time, it will become heavier and heavier, and the endometrium will lose its function after becoming severe adhesion. Even if it is treated again, it is very difficult to get pregnant again. 3. If amenorrhea is caused by ovarian dysfunction or ovarian decline, patients will enter the old age ahead of time without continuing treatment, and there will be menopausal symptoms such as hot flashes, night sweats, inattention, irritability, etc., and osteoporosis and cardiovascular diseases will occur ahead of time, which will seriously endanger the quality of life of patients.
