Is endometrial thickness 6 normal?

An endometrial thickness of 6 mm may be normal or abnormal at different stages of the menstrual cycle and needs to be judged based on the specific period. Endometrial thickness changes cyclically due to hormone levels, and the main evaluation criteria include the menstrual phase, proliferative phase, and secretory phase.

The endometrium is the thinnest after the menstrual period, usually 1-4 mm. At this time, 6 mm may indicate incomplete shedding. The proliferative phase is the stage of follicular development. The endometrium thickens at a rate of 0.5 mm per day, and it is normal to reach 6-10 mm before ovulation. The secretory phase is formed after ovulation, and the endometrium continues to thicken to 7-16 mm in preparation for pregnancy. At this time, 6 mm may indicate insufficient luteal function. Postmenopausal women should be wary of lesions if their endometrium exceeds 5 mm.

Pathological thinning is common in organic diseases such as intrauterine adhesions and endometrial tuberculosis, and may be accompanied by reduced menstrual flow or amenorrhea. Abnormal thickening needs to exclude the risk of endometrial hyperplasia, polyps or malignant transformation, and is usually accompanied by irregular bleeding. Ultrasound examination is recommended to be performed within 3 days after menstruation to avoid false thickening interference during ovulation. Hysteroscopy is the gold standard for assessment of endometrial structure and can be performed concurrently with biopsy.

Maintaining a regular schedule can help stabilize hormone levels and avoid excessive dieting that can lead to malnutrition. Soy products contain phytoestrogens, which can be supplemented in moderation, but cannot replace drug treatment. If you find abnormal bleeding or cycle disorders, you should seek medical treatment promptly. It is forbidden to take hormone drugs to regulate the endometrium by yourself. Regular gynecological examinations can detect endometrial lesions early, especially those with a family history of cancer or long-term anovulatory menstruation, which require enhanced monitoring.
