Introduction
Menstruation typically involves bleeding. However, if a patient has intrauterine adhesions, bleeding may not occur. The detailed explanation is as follows: Menstruation is a cyclical physiological phenomenon in females, characterized by regularity and serving as an indicator of reproductive maturity. Under the influence of the ovaries, increased estrogen levels in the female body promote thickening of the endometrium, accompanied by edematous changes.
Menstruation usually involves bleeding. However, if a patient has intrauterine adhesions, there may be no bleeding. The specific analysis is as follows:
1. Yes
Menstruation is a regular, cyclical physiological process in females and signifies the maturity of reproductive organs. Under the influence of the ovaries, rising estrogen levels cause the endometrium to thicken and exhibit edema. After ovulation, if fertilization does not occur, the corpus luteum gradually atrophies and stops producing estrogen, leading to shedding of the endometrium, resulting in menstrual bleeding.
2. No
If a woman has had multiple pregnancies or undergoes diagnostic curettage with improper technique, the basal layer of the endometrium may become damaged, increasing its fragility and impairing endometrial proliferation. This can lead to localized mucosal adhesion within the uterine cavity—known as intrauterine adhesions—which prevents menstrual blood from being discharged. Surgical treatment at a hospital is recommended in such cases.
It is advised that during menstruation, one should avoid excessive fatigue, change underwear frequently, and prevent local skin contamination by menstrual blood. If abnormal conditions such as a sudden decrease in menstrual flow occur, prompt medical consultation is recommended.
