Endometrium 7mm alone does not have clinical significance, and the significance of 7mm needs to be judged under a comprehensive and holistic examination, as follows: 1. If an elderly postmenopausal woman has no bleeding, endometrium 7mm is abnormal, which may be endometrial hyperplasia, endometrial cancer, polyps and other conditions. 2. 7mm of endometrial lining in women of childbearing age cannot be judged to be of specific significance, but may be normal. Since menstruation has just ended, a 7mm endometrial lining may be the endometrial lining of the uterus just after menstruation, and the endometrial lining will still grow thicker. If the endometrium is only 7mm when it is at its thickest in the middle of menstruation, it indicates that the endometrium is thin, possibly due to a miscarriage or insufficient hormone levels, resulting in a thinning of the endometrium. The main way to check the thickness of the endometrium is through abdominal ultrasound or vaginal ultrasound, and it is recommended that patients go to the hospital 2~3 days after their menstrual period.
