Patient's question:
NoDoctor's answer:
There are many reasons that can cause a decrease in menstrual flow, such as endocrine disorders, low levels of female hormones, and other gynecological diseases. Generally, a decrease in menstrual flow is caused by low estrogen levels. Estrogen can stimulate the proliferation and thickening of the endometrium, preparing it for pregnancy. If pregnancy does not occur, the proliferated endometrium will shed and bleed, forming a menstrual period. Low estrogen levels in the body can lead to insufficient thickening of the endometrium.
