Why does the endometrium become thinner instead of menstruation?

The thickness of a woman's normal endometrium will change with her menstrual cycle. This situation is not constant. Usually, the thickness of a woman's endometrium will become thinner at the end of the menstrual cycle, and a week after the menstrual cycle, the endometrium will become thicker. However, many female friends have encountered the situation where the endometrium becomes thinner without menstruation. So, why does the endometrium become thinner without menstruation?

First, why does the endometrium become thinner instead of menstruation? Thin endometrium means that under the action of estrogen, the thickness of the endometrium of a woman is measured to be less than 7mm through B-ultrasound examination. This is the symptom of thin endometrium. When the endometrium is thin, the fertilized egg cannot implant well on the uterine wall, and pregnancy cannot occur successfully. The endometrium is the layer that makes up the lining of the uterus. It responds to both estrogen and progesterone, and its thickness changes with the menstrual cycle. If a woman has some bad living habits that lead to endocrine disorders, it will cause hormone imbalance in the body, which will in turn cause a disorder in the cyclical changes of the endometrium and cause the endometrium to become thinner.

Second, artificial abortion is also one of the main culprits for the thinning of women’s endometrium. Studies have found that multiple medical or surgical abortions can cause the endometrium to thin. Moreover, some women even experience amenorrhea after having a miscarriage. This is because miscarriage damages the endometrium, causing it to become thinner and unable to shed, leading to amenorrhea. This clearly illustrates how serious the damage abortion can do to a woman's body. The more abortions you have, the thinner the endometrium will become. When it is less than 7mm, infertility may follow.

Why does the endometrium become thinner instead of menstruation? Malformation of the female uterus is also a reason for the thin endometrium, but this factor is often overlooked because most women do not feel it. When this congenital uterine malformation occurs and causes the problem of thin endometrium, it is generally difficult to treat clinically.
