Is it normal for the endometrium to be 7mm thick?

The thickness of a woman's endometrium is usually between 5 and 10 mm, but this value is not an absolute value. It is normal to have a slight fluctuation between these two values. Because there are many factors that affect the thickness of the endometrium, it may also change with the changes in the female menstrual cycle, and its thickness may vary in the same period of time.

1. Normal thickness of the endometrium

The normal thickness of the endometrium is generally between 5 and 10 mm. The thickness of the endometrium varies at different stages:

1. Proliferative stage: In the late stage of hyperplasia, the normal thickness of the endometrium increases to 3-5mm.

2. Secretory phase: From the 15th to the 28th day of menstruation, the thickness of the endometrium reaches 5 to 7 mm.

3. Ovulation period: endometrial thickness is 8-12mm.

Note: The thickness of the endometrium will affect women’s menstrual period, endocrine system, and even their reproductive ability. Female friends must pay attention to this.

Why do endometrial abnormalities occur?

1. Causes of thin endometrium:

Endometrial lesions: such as endometrial polyps, endometrial cancer, etc.

Endocrine disorders: Women’s emotions have a great impact on the endometrium.

Abortion curettage: Abortion curettage can damage the middle and bottom layers of the endometrium, resulting in a thin endometrium.

2. Causes of thick endometrium:

Obesity: Obese women have more fat tissue and higher levels of estrone in their plasma, which can cause persistent estrogen and lead to endometrial thickening.

Endocrine disorders: Long-term endocrine disorders may not only cause endometrial thinning, but also endometrial thickening, so be careful!

Other reasons: If a certain link of the hypothalamus-pituitary-ovarian axis is out of balance or polycystic ovary syndrome occurs, ovulation may not occur, causing the endometrium to be continuously affected by estrogen for a longer period of time, leading to endometrial thickening.
