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 the cyclical changes of the ovaries. If the uterus is underdeveloped, such as being very small or malformed, only a small amount of endometrium may shed during each physiological cycle, leading to a light menstrual flow. Additionally, conditions like endometrial tuberculosis causing endometrial lesions or procedures such as dilation and curettage that damage the endometrium can also result in a light menstrual flow or even amenorrhea.
2. Hormonal secretion abnormalities. Estrogen stimulates the proliferation of the female endometrium. If hormonal secretion in the body is abnormal, the endometrium may not grow to the required thickness, resulting in a light menstrual flow. Extreme dieting, irregular sleep patterns, poor emotional health, and reproductive system diseases can all affect a woman's endocrine environment, leading to abnormal hormone secretion and a light menstrual flow.
3. Anovulatory menstruation. Women without ovulation may 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 very light blood flow.
