Uterine adhesions are more harmful and need to be dealt with as early as possible, including pain in the lower abdomen, abnormal menstruation, miscarriage or causing infertility. Uterine adhesions are related to women who have had uterine operations, such as abortion and diagnostic scraping, and are categorized as cervical canal adhesions and uterine cavity adhesions. Among them, uterine adhesions can cause conditions such as missing endometrium and thinning of endometrium, which can induce women to have reduced menstrual flow, amenorrhea, dysmenorrhea, infertility and so on. If some women get pregnant, because of the endometrial defect, it causes abnormal attachment of the gestational sac, which may lead to abdominal pain, vaginal bleeding, and other preeclampsia in early pregnancy. In addition, cervical canal adhesion can also cause menstrual blood retention, which makes it difficult to discharge menstrual blood, periodic lower abdominal pain, and ultrasound examination suggests that there is a large amount of fluid in the uterine cavity. Women should pay attention to the use of contraceptive measures during intercourse, try to avoid unwanted pregnancy, reduce the damage to the uterine cavity due to abortion, and reduce the occurrence of uterine adhesions.
