Why do menstrual irregularities occur after abortion?

Abortion is a common method to end an unwanted pregnancy. Many patients may experience menstrual irregularities after the operation, such as prolonged menstrual cycles, increased menstrual flow, etc. The main reasons are as follows.

1. Surgical injury

Abortion is very harmful to women's ovaries and uterus. Repeated curettage causes the endometrium to become weak and unable to regenerate. Long-term use of this will cause amenorrhea. In addition, improper abortion surgery may damage the basal layer of the endometrium, causing scanty menstruation, irregular menstrual cycles, etc. If the endometrium is severely damaged, it will cause amenorrhea or even menopause.

2. Patient's mental factors

Menstruation in women is the result of the interaction between the cerebral cortex, hypothalamus, pituitary gland, ovaries and uterus, and is regulated by neuroendocrine. Some women who undergo abortions have a heavy mental burden, are overly nervous and anxious before the operation, are afraid of abortion, or have a mental burden due to not being able to get pregnant and have children. Especially those who get pregnant before marriage have too much guilt and self-blame. When people are in such negative emotions, they can inhibit the functions of the hypothalamus, pituitary gland, ovaries and uterus through the neuroendocrine system, thus causing abnormal menstruation.

3. Not paying attention to hygiene after abortion

Abortion surgery can cause great harm to the patient's body and will also cause serious damage to the endometrium, reducing its immunity to the outside world. If the patient is not properly cared for at this time and becomes infected, it may cause bacterial invasion, cause irregular menstruation, etc., and endanger women's reproductive health.
