How thick is the endometrium after miscarriage? Why does the endometrium become thinner?

The uterus is a very important reproductive organ for women and is also the place where the fetus develops in the mother's body, so you must take good care of your uterus. Women's metabolism will accelerate with the arrival of menstruation, and the thickness of the endometrium in the body will also change. So, what is the normal thickness of the endometrium after abortion?

What is the normal thickness of the endometrium after miscarriage?

During the abortion process, female friends undergo curettage, which causes changes in the thickness of the endometrium and affects female fertility. Generally, the thickness of the endometrium will be damaged due to too many curettages and too heavy curettage operations. After the abortion, the thickness of the endometrium becomes thinner, causing a decrease in menstrual volume. Therefore, if there is a significant decrease in menstrual volume after an abortion, it may be caused by a problem with the thickness of the endometrium.

At this time, when menstruation is slightly reduced, you can measure the basal body temperature to judge whether it is the endocrine effect or the uterus. If the basal body temperature is a typical biphasic, it means that there may be a normal ovulation period, no endocrine problem, and the problem is in the uterus; in the middle of the menstrual period, do B-ultrasound to measure the thickness of the endometrium after abortion. If the endometrium is not thick enough, it can be determined that the endometrium is damaged. So what is the normal thickness of the endometrium after abortion? What is the change in endometrial thickness?

Normal range of proliferative endometrial thickness: Around day 5-9 of the menstrual cycle, the endometrium is very thin.

Normal range of endometrial thickness during the secretory phase: On the 15th to 19th day of the menstrual cycle, 1 to 5 days after ovulation, the endometrium continues to thicken, and the glands further increase in size and bend. Around the 20th to 24th day of the menstrual cycle, 6 to 10 days after ovulation, the endometrium shows high secretory activity, and the curvature and expansion of the glands reach a peak. In the late secretory phase, the thickness of the endometrium is about 5 to 6 mm.

The normal range of endometrial thickness in the premenstrual period is: about 25 to 28 days of the menstrual cycle, which is 11-14 days after ovulation, the thickness of the endometrium decreases by 1/5-1/3.

The normal range of endometrial thickness during menstruation: approximately on the 1st to 4th day of the menstrual cycle, the main changes are endometrial bleeding and shedding.

Causes of thin endometrium

When women have a certain amount of estrogen and their endometrium does not reach a thickness of 8 mm during ultrasound examination, they are judged to have thin endometrium. The causes of thin endometrium are divided into systemic factors and local factors. Systemic factors include endocrine disorders, such as low estrogen levels, insufficient progesterone, ovulation disorders and growth hormone deficiency; local factors are mainly endometrial damage, adhesion and absence.

Reason 1 for thin endometrium: severe endocrine disorder

The endometrium refers to a layer that constitutes the inner wall of the mammalian uterus. It responds to both estrogen and progesterone, and therefore can undergo significant changes with the sexual cycle. Gynecologists point out that estrogen can cause uterine hypertrophy, and progesterone can cause special changes in the endometrium during early pregnancy, or change the nature of the endometrium, giving it the ability to produce decidua. Therefore, severe endocrine disorders will lead to hormonal imbalances in the body, causing disorder in the cyclical changes of the endometrium, resulting in thin endometrium. Thin endometrium caused by simple endocrine factors can be clinically adjusted with hormones. Appropriate amounts of estrogen and progesterone can increase the thickness of the endometrium to a certain extent and improve the symptoms of thin endometrium.

The second reason for thin endometrium: artificial abortion

Artificial abortion is the main factor causing thin endometrium. Experts point out that multiple medical abortions or excessive abortion movements may cause thin endometrium. Some patients even haven't had their periods after an abortion. This shows that abortion has seriously damaged the endometrium and caused a thin endometrium.

Gynecological experts point out that the thin endometrium caused by artificial abortion usually takes a long time to recover, and some patients may not even be able to recover. Therefore, experts especially remind patients that if menstruation does not come on time after an abortion, they must see a doctor for examination.
