There are so many causes of uterine adhesions

Uterine adhesion refers to adhesion caused by inflammation in the uterine cavity, of which pregnancy factors account for 25%, non-pregnancy factors account for 30%, surgical inflammation factors account for 30%, human factors account for 10%, and other factors account for 5%. This disease is extremely harmful and must be treated symptomatically.

Pregnancy factors (25%):

Pregnancy-related intrauterine surgeries include early pregnancy vacuum aspiration, mid-pregnancy forceps curettage, mid-pregnancy induced labor curettage, postpartum hemorrhage curettage and spontaneous abortion curettage. This may be because the basal layer of the endometrium of the pregnant uterus is more easily damaged, causing the uterine walls to adhere to each other and form permanent adhesions.

Non-pregnancy factors (30%):

Myomectomy (entering the uterine cavity), transuterine removal of submucosal uterine myomas, hysterectomy, and double uterus surgery destroy the basal layer of the endometrium, exposing the myometrium to the uterine cavity and leading to anterior and posterior adhesions of the uterine wall.

Surgical inflammatory factors (30%):

Intrauterine infection includes uterine tuberculosis, postmenopausal senile endometritis, secondary infection after uterine operation, puerperal infection, secondary infection after intrauterine contraceptive device placement, etc.

Human factors (10%):

Artificially destroy the basal layer of the endometrium to cause intrauterine adhesions. Such as: after endometrial electrosurgical resection, intrauterine microwave, cryotherapy, chemotherapy and local radiotherapy.

Other factors (5%):

If the uterus is repeatedly curettaged, it is very easy to damage the basal layer. The intrauterine adhesion caused by this reason is called traumatic adhesion, which is the most common. Therefore, obstetricians and gynecologists should use appropriate depth of curettage. Women of childbearing age should implement contraceptive measures and avoid abortion, especially for the first abortion, which may cause secondary infertility due to intrauterine adhesion.
