The risks of uterine adhesions include pain in the lower abdomen, abnormal menstruation, miscarriage or infertility. Uterine adhesions are associated with a woman’s history of uterine operations, such as abortion and diagnostic curettage. The danger consists of three main aspects. On the one hand, there is periodic pain in the small abdomen, and uterine adhesions can cause retention of menstrual blood, difficulty in expelling menstrual blood, and in severe cases, fidgeting and difficulty in moving, and ultrasound examination suggests fluid accumulation in the uterine cavity. The pain usually lasts 3-7 days and comes in cyclic episodes. On the other hand, menstrual abnormalities. Uterine adhesions can cause decreased menstrual flow, amenorrhea and dysmenorrhea in women due to the absence of endometrium and thinning of the endometrium. In addition, it can also cause infertility, premature birth or miscarriage. In some women’s pregnancies, due to uterine adhesions, the endometrium is defective, causing abnormal attachment of the gestational sac, which may lead to abdominal pain, vaginal bleeding and other aura miscarriage or even miscarriage in early pregnancy, and infertility in severe cases.
