Patient's question:
Normal menstrual cycle, less menstrual flow, dark color, lasting for several yearsDoctor's answer:
Hello: Generally speaking, a small amount of menstrual flow is usually caused by low estrogen levels. Estrogen can stimulate the proliferation and thickening of the endometrium. The proliferated endometrium detaches and bleeds to form menstruation. Low estrogen levels in the body can lead to insufficient endometrial thickening, resulting in less bleeding during menstruation. For your condition, it is recommended that you undergo an endocrine examination to check whether the hormone levels in your body are normal.
