What is the shedding of the endometrium?

Some women say that menstruation is not caused by their own estrogen secretion, but by the thickening of the endometrium. In fact, this view is not entirely wrong. After all, there is still a lot of shed endometrium in menstrual blood. So from a scientific point of view, what is the reason why women experience endometrial shedding?

Menstruation occurs because of the thickening of the endometrium, and the shedding of the endometrium is the process of menstruation. It is the same for all women. After menstruation, the inner wall of the uterus will be very thin. The endometrium will grow upwards little by little, and when it reaches a certain thickness, menstruation will occur. If you become pregnant at this time, the fertilized egg will attach to the endometrium. It is preparing for pregnancy anytime and anywhere. Therefore, it is normal for the endometrium to shed normally, but if the endometrium sheds a lot, you need to go to the hospital for relevant examinations.

Endometritis is a common disease among women of childbearing age, often causing dysmenorrhea, dyspareunia and infertility. Laparoscopy is currently the gold standard for diagnosing the disease. North China Hospital uses this technology not only to clearly define the stage, but also to perform treatments at the same time, such as cauterization and vaporization of intra-abdominal lesions, loosening of pelvic adhesions, and removal of uterine cavity residues, with unique therapeutic effects.

What is endometrial shedding?

Endometrial shedding and corpus luteum dysfunction are different from the above. During the menstrual cycle, the patient ovulates and the corpus luteum develops well, but the atrophy process is prolonged, resulting in the shedding of the endometrium.

Causes of endometrial shedding

The corpus luteum generally shrinks after 14 days, and the endometrium falls off due to lack of support from estrogen and progesterone, causing menstruation. Irregular endometrial shedding is caused by dysfunction in the regulation of the hypothalamus-pituitary-ovarian axis, which leads to incomplete corpus luteum atrophy. The endometrium is continuously affected by progesterone, so it cannot be shed completely as expected. On the 3rd to 4th day of a normal menstrual period, the secretory endometrium has completely shed and is replaced by regenerated proliferative endometrium. However, when the endometrium is shed irregularly, the endometrium showing secretory reaction can still be seen on the 5th-6th day of the menstrual period. Because the patient's menstrual period is long, the endometrium loses water, the interstitium becomes dense, the glands shrink, and the glandular cavity becomes plum blossom or star-shaped. The endometrium showed a mixed type, that is, the residual secretory endometrium coexisted with hemorrhagic necrotic tissue and newly grown endometrium.
