Expected help: What causes a decrease in menstrual volume?
Doctor's answer:
The reasons for a light menstrual flow mainly include the following three aspects:1. Uterine developmental abnormalities. Menstruation is the shedding of the endometrium accompanied by changes in the ovarian cycle, leading to bleeding. If the uterus is underdeveloped, such as being very small or malformed, only a small amount of endometrium may shed during each physiological cycle, resulting in a light menstrual flow. Additionally, conditions like endometrial tuberculosis causing endometrial lesions or procedures such as dilation and curettage can damage the endometrium, leading to a light menstrual flow or even amenorrhea.
2. Abnormal hormone secretion. Estrogen stimulates the proliferation of the female endometrium. If hormone secretion in the body is abnormal, the endometrium may not grow to the required thickness, leading to a light menstrual flow. Factors such as extreme dieting, irregular sleep patterns, poor emotional health, and reproductive system diseases can affect a woman's endocrine environment, causing abnormal hormone secretion and resulting in a light menstrual flow.
3. Anovulatory menstruation. Women without ovulation can still experience menstruation, which is medically referred to as "anovulatory menstruation." This differs from normal menstruation and falls under the category of "functional uterine bleeding." The characteristics of this type of menstruation include irregular timing and a very small blood volume.
