Reasons for decreased menstrual flow after abortion

Reasons for decreased menstrual flow after abortion

There are many reasons why patients have less menstrual volume after abortion. After abortion, patients may have insufficient endometrial hyperplasia due to endometrial damage, uterine cavity adhesions, endocrine system dysfunction, and incomplete curettage during surgery, which leads to reduced menstrual volume.

Damage to the uterine lining

Excessive curettage during abortion surgery or multiple abortions can cause damage to the patient's endometrium, resulting in complete or partial loss of the endometrium in the uterine cavity, which can prevent the endometrium from exfoliating cyclically normally and cause scanty menstruation after abortion.

Uterine adhesions

The endometrium is damaged during abortion and curettage, and adhesions may occur after the operation. If adhesions occur in the patient's uterine cavity, there may be different manifestations depending on the degree of adhesion. A large adhesion range may cause amenorrhea, while a small adhesion range may cause less menstrual flow after abortion.

Endocrine disorders

After abortion, patients may have endocrine system dysfunction, hypopituitarism, insufficient ovarian estrogen secretion, insufficient endometrial hyperplasia, and thin endometrium, resulting in less bleeding during menstruation and less menstrual flow. Long-term use of contraceptives can inhibit pituitary function, resulting in insufficient estrogen secretion and reduced menstrual flow after abortion.

Incomplete curettage

A small number of patients may experience amenorrhea or scanty menstruation after miscarriage due to incomplete curettage and residual placenta and other tissues in the endometrium. In this case, another curettage can restore the patient's menstruation to normal.
