What is the reason for less menstrual flow after abortion?

After a woman becomes pregnant, she may suffer from many factors that lead to miscarriage, which is very harmful to the body for women. Women not only have to bear the physical pain, but also have to bear a lot of psychological pressure. Some women who have had miscarriages will find that their menstrual flow becomes less and less. So what is the reason for the low menstrual flow after abortion?

Reasons for light menstrual flow after abortion

1. Incomplete curettage leads to amenorrhea or decreased menstrual period. The menstrual volume after abortion is small. In rare cases, amenorrhea or shortened menstruation may occur due to residual embryonic tissue or other tissues after incomplete curettage. The menstrual period can be restored after another curettage.

2. The uterine wall is damaged and adhesions occur during abortion and curettage. The menstrual volume is small after abortion, the menstruation is abnormal after abortion, the cervix, endometrium or uterine wall is damaged during abortion curettage, and adhesions are produced after the operation. If the cervical canal is adhered, menstruation cannot be discharged. Such patients usually have regular abdominal pain once a month. If there is cervical adhesion, the manifestations will vary depending on the degree. A large adhesion may cause amenorrhea, while a small adhesion may shorten the menstrual period.

3. Abnormal growth hormone metabolism or anovulation. Small menstrual flow after abortion is generally related to endocrine disorders, such as abnormal metabolism of various hormones or anovulation. In addition, it may be due to the uterine wall itself, such as uterine wall tuberculosis leading to endometrial degeneration or abortion, curettage leading to thin endometrium, etc.

4. Endometrial damage in the uterine cavity. Too many or frequent abortions will lead to frequent damage to the uterine wall, damage to the endometrium in the entire uterine cavity or milky white scars, and loss of regular menstrual periods caused by endometrial shedding.

5. Menstrual disorders. After abortion, the uterus and ovaries can generally resume ovulation function within 22 days, and menstruation will begin in about January. However, a very small number of women experience menstrual disorders such as prolonged menstruation, amenorrhea, and irregular cycle duration after abortion. This condition usually recovers after 2-3 months.

6. Insufficient luteal function. Insufficient luteal function, some patients have endocrine abnormalities such as premature ovarian failure, hypothalamic pituitary amenorrhea and hyperlactationuria or uterine and ovarian anovulation.

7. Frequent abortions or rough surgical treatments. Frequent abortions or rough surgical treatments can damage the uterine dermis and endometrium or cause intrauterine adhesions, all of which can lead to oligomenorrhea. Postpartum hemorrhage sometimes first manifests as oligomenorrhea and then amenorrhea.

The change in menstrual volume after abortion indicates that there is a certain abnormality in the human body. Some experts remind everyone that a decrease in menstrual period after painless abortion is a normal phenomenon and it can usually be recovered in a short time. However, if it does not recover for a long time, you should go to the hospital for regular examination and treatment in time.
