What is endometrial thickness?

Patients with thick endometrium will feel extremely severe dysmenorrhea every time they have their menstruation, which may even be unbearable. This leads to many female friends relying on painkillers to improve their dysmenorrhea. Some female friends also have difficulty in implanting the fertilized egg due to the thick endometrium, which makes it impossible for them to have normal children.

The thickness of the endometrium is different at different stages of the menstrual cycle. It is recommended to do a vaginal B-ultrasound three days after the end of menstruation to understand the specific thickness of the endometrium. If the endometrium is thick, menstruation is likely to be very painful and the fertilized egg will have difficulty implanting!

It means that the endometrium is thicker than normal. The thickness of the endometrium cannot determine whether you can get pregnant. Whether ovulation occurs is the key to whether you can get pregnant. The normal range is 0.2-1.0 cm.

The endometrium is the mucous membrane covering the uterine cavity and is one of the most differentiated tissues in the human body. The thickness of the normal endometrium changes with the menstrual cycle and is not constant. [1]

Endometrial hyperplasia has a certain tendency to become cancerous, so it is classified as a precancerous lesion. However, based on long-term observations, the vast majority of endometrial hyperplasia is a reversible lesion or maintains a persistent benign state. Only in a few cases may cancer develop after a longer time interval.

It is divided into three types according to the changes in glandular structure and morphology and the presence or absence of glandular epithelial cell atypia: ① Simple hyperplasia: a physiological response of the endometrium caused by long-term stimulation of estrogen without progesterone antagonism. The stroma and glands proliferate simultaneously without glandular crowding, and the morphology of the glandular epithelium is not atypical. ② Complex hyperplasia: The glands in the lesion area are crowded, the stroma is significantly reduced, and there is no atypia of the glandular epithelial cells. ③ Atypical hyperplasia: The glandular epithelium is atypical and belongs to the intraepithelial neoplasm of the endometrium. According to the severity of the lesion, it is divided into three degrees: mild, moderate and severe.

The endometrium is the mucous membrane covering the uterine cavity and is the most differentiated tissue in the human body. The thickness of normal endometrium generally changes with the menstrual cycle and is not constant.

The specific numbers are: 1. Menstrual period: the functional layer of the endometrium falls off and the basal layer remains. 2. Proliferative phase: The endometrium thickness reaches 1-3mm during the 6th to 14th day of menstruation. 3. Secretory phase: The endometrium thickness reaches 5-7mm during the 15th to 28th day of menstruation.
