What is the normal endometrial thickness during menstruation?

Compared with endometrial tissue and organs,女性朋友 should be more familiar with the endometrium, as it plays a crucial role in women’s health and future fertility. In daily life, many women experience abnormal thickening or thinning of the endometrium due to various causes—causing concern for some.

What is the normal endometrial thickness during menstruation?

The normal endometrial thickness during menstruation ranges from 8 to 12 mm. If the endometrium is too thin, it may result in scanty menstrual flow or prolonged periods—commonly associated with endometritis, endometrial defects, or prior intrauterine surgery. Conversely, excessive endometrial thickening can also affect menstrual volume, leading to menorrhagia (heavy bleeding), clots, and even severe hemorrhage—potentially causing hemorrhagic shock or dysfunctional uterine bleeding. Moreover, markedly abnormal endometrial thickness warrants evaluation for possible malignant endometrial lesions. Therefore, if menstrual abnormalities occur, a follow-up pelvic ultrasound is recommended, followed by further management tailored to both endometrial findings and the patient’s clinical presentation.

Note: Chronic psychological stress and mental tension may disrupt endocrine function. Such endocrine imbalance can contribute to endometrial hyperplasia; thus, maintaining psychological well-being is essential to prevent hormonal dysregulation. Weight control is also critical—obese women often experience increased metabolic burden and hormonal fluctuations, which may promote endometrial thickening.

In daily life, cultivating healthy lifestyle and dietary habits is highly recommended. We hope this information is helpful to you.
