What is the normal thickness of the uterus?

During gynecological examinations, many women are found to have varying uterine wall thicknesses. As the uterus is a vital organ, women naturally pay close attention to this parameter—so what is considered a normal uterine thickness?

What Is a Normal Uterine Thickness?

The normal thickness of the endometrium (uterine lining) depends on the patient’s menstrual status. Since endometrial thickness closely correlates with the menstrual cycle—primarily due to fluctuating progesterone levels across different phases—the thickness varies accordingly. Immediately following menstruation, the endometrium is at its thinnest, measuring approximately 0.2–0.3 cm; during this phase, the endometrium has been completely shed and hormone levels are low, so no significant endometrial growth occurs. Prior to ovulation, the endometrium should measure at least 0.7 cm, and just before menstruation begins, it typically reaches about 1.0 cm.

The uterus is a key reproductive organ in women and serves as the site for fetal development. Maintaining uterine health is essential for overall female well-being and helps prevent various gynecological disorders. To support uterine health, women should consume foods that nourish Qi and blood. In daily life, it is advisable to eat more foods rich in vitamins C and E—such as soy products, nuts, radishes, vegetables, fruits, red dates, red beans, and animal offal. If signs of inflammation or discomfort arise, prompt anti-inflammatory treatment is necessary.

Maintain good personal hygiene, avoid sexual intercourse during menstruation, keep warm during your period, limit intake of cold foods, use appropriate contraceptive methods, and prevent unintended pregnancies and associated uterine trauma such as abortion.
