What is the normal thickness of the endometrium during lactation?

The thickness of the endometrium varies at different times. It is mainly divided into four periods, including the proliferative phase, secretory phase, premenstrual phase and menstrual phase. During the lactation period, endometrial thickening is prone to occur, which is an atypical hyperplasia. A clear diagnosis is needed to understand the specific cause of the hyperplasia. Let's take a look at the normal thickness of the endometrium during lactation.

What is the normal thickness of the endometrium during lactation?

What is the normal thickness of the endometrium after childbirth? Although this is a common sense question, many women are still unclear and curious about it. So let's take a look at what is the normal thickness of the endometrium after childbirth!

Generally speaking, the thickness of the endometrium varies at different times. It is divided into the following four periods.

1. Proliferative phase: Around the 5th to 9th day of the menstrual cycle, the endometrium is very thin.

2. Secretory phase: From the 15th to the 19th day of menstruation, which is 1 to 5 days after ovulation, the endometrium continues to thicken and the gland further increases in size and curvature. Around the 20th to 24th day of the menstrual cycle, which is 6 to 10 days after ovulation, the endometrium shows a high degree of secretory activity, and the curvature and expansion of the gland reach a peak. In the late secretory phase, the thickness of the endometrium is about 5 to 6 mm.

3. Premenstrual period: About 25th to 28th day of the menstrual cycle, which is 11 to 14 days after ovulation, the thickness of the endometrium decreases by 1/5 to 1/3.

4. Menstrual period: approximately from the 1st to the 4th day of the menstrual cycle, the main changes are endometrial bleeding and shedding. The endometrium changes at different stages of the menstrual cycle.

It can be seen that because the endometrium has the characteristics of periodic changes, it is not fixed, but the endometrium during ovulation is usually larger than 1 cm, which is beneficial for the implantation of the fertilized egg, and the normal endometrium is usually between 0.5-1.0 cm.

What to do if endometrial thickening occurs during lactation

The treatment of atypical endometrial hyperplasia must first determine the diagnosis and the cause of the atypical hyperplasia, including whether there is polycystic ovary, functional ovarian tumors or other endocrine dysfunction. Those with any of the above conditions should receive targeted treatment. At the same time, symptomatic treatment can be started for atypical endometrial hyperplasia, using drug therapy or surgical treatment. The choice of these two treatment options should be based on age, type of endometrial hyperplasia, fertility requirements, etc.

Abnormal endometrial thickening can lead to infertility. The endometrium is affected by the hormone levels in the body. If it thickens excessively, it is mainly caused by changes in hormone levels. This can not only affect menstruation, but may also affect normal ovulation, and is not conducive to the implantation of the fertilized egg, leading to habitual miscarriage or infertility. It is recommended to do a vaginal B-ultrasound three days after the end of menstruation to observe the specific thickness of the endometrium. If the endometrium is too thick, menstruation will be very painful, and the fertilized egg will not be easy to implant.
