Induced abortion can easily damage the endometrium or affect future pregnancies

In women, the functional layer of the endometrium is shed at the onset of menstruation, and then it begins to proliferate and repair from the basal layer. If the basal layer is damaged, the endometrium loses its ability to repair. At this time, even if the ovaries are functioning normally, there will be no menstrual cramps.

Amenorrhea is likely to occur if the basal layer of the endometrium is damaged during abortion surgery. Because the uterine cavity is not covered by an endometrium, adhesions may occur in the anterior and posterior walls. Depending on the size of the damaged basal layer of the endometrium, the clinical manifestations are also different.If the basal layer is completely damaged, the anterior and posterior walls of the uterine cavity are completely adherent, and the patient can be completely amenorrhea; If part of the basal layer is still present, it is manifested by decreased menstrual flow; If the intrauterine adhesion site is close to the uterine opening, and there is still a healthy endometrium above the adhesions, menstrual abdominal pain, menstrual blood and even hysterosis may occur due to the unobstructed menstrual blood outflow; If the endometrium is not damaged but only the endometrium of the cervical canal is damaged, causing adhesions in the cervical canal, severe periodic lower abdominal pain may occur without menstrual cramps.

In addition to induced abortion, postpartum curettage can also cause intrauterine adhesions. Severe purulent endometritis and tuberculous endometritis can also cause destruction of the basal layer of the endometrium and cause amenorrhea.

Although there is no menstrual cramps after the destruction of the basal layer of the endometrium, the ovarian function is normal, and if there are no other symptoms and there is no desire to have children, no treatment can be given. Tuberculous or purulent endometritis must be treated for the underlying condition, but the endometrium does not repair itself after treatment, and the patient still presents with amenorrhea.
