Patient's question:
On February 19th, the menstrual flow had already started to decrease. I want to ask what causes a decrease in menstrual flow and is it normal?Doctor's answer:
The menstrual cycle is basically normal, but the amount of menstrual flow is significantly reduced, or even stops after a few drops, or the menstrual period is shortened to less than two days with a small amount of flow. This is called hypomenorrhea, also known as "thin menstruation." It is generally believed that a menstrual flow of less than 30 milliliters is equivalent to "hypomenorrhea" in Western medicine's category of menstrual disorders. If the menstrual cycle becomes stable but the amount of blood flow remains persistently low, and it is not caused by nutritional deficiencies, while also noticing poor physical development such as underdeveloped breasts and buttocks, it is necessary to be cautious and seek medical attention promptly for a follow-up examination to check estrogen levels. If estrogen levels are found to be low, the underlying cause should be identified, as it is mostly due to endocrine system disorders.
