If the endometrium falls off a whole pile, it is generally a normal physiological phenomenon if it is during menstruation. Some women have thicker endometrial tissues, so even when they shed normally, a large pile will be shed; however, if the endometrium is shed irregularly, it may be a pathological condition that requires timely medical treatment. During menstruation, the estrogen and progesterone in women of childbearing age will drop, resulting in regular shedding of the endometrium with the menstrual cycle, because the thickness of the endometrium and the rate of shedding varies from person to person, some women may experience a whole pile of endometrium falling off, etc. There is no need to worry too much. During menstruation, women should pay attention to avoid strenuous exercise, avoid spicy and stimulating food, and drink some brown sugar water to relieve physiological abdominal pain, but do not drink brown sugar water if the endometrium is shed in large quantities to cause discomfort, because brown sugar can, to a certain extent, promote the dissolution of blood stasis and dispersion, which may have the opposite effect. When women have hormone regulation disorder, luteal atrophy incomplete or lasting too long, it will cause estrogen and progesterone in the body to drop, and the phenomenon of irregular shedding of endometrium will appear, which is manifested as endometrium falling down in a whole pile or flocculent shedding, abnormal uterine bleeding, heavy bleeding, prolonged menstrual period, and dripping menstrual blood. In this case, you need to go to the hospital for a hormone six test or take the endometrium on the fifth day of menstruation for pathological examination to improve the irregular shedding of endometrium after clear diagnosis and treatment under the guidance of doctors, such as progesterone supplementation.
