During menopause, which is also known as perimenopause, whether or not a lining thickness of 8mm is normal needs to be viewed in the context of menstruation. If you are in a state where you are about to menstruate, then it may be normal, and if you have just finished menstruating, then there may be a problem with this thickness.
Perimenopause is a special time for women. During this period, a woman’s ovarian function gradually diminishes, but she still has her period. Under the action of estrogen, the endometrium proliferates cyclically, and in the late endometrial secretion stage it can be up to 10mm, so if ultrasound examination is performed during this period, an endometrial thickness of 8mm is normal.
If the endometrium is 8mm thick after the endometrial lining is shed at the end of menstruation, the ultrasound examination will show that the endometrium is thicker than the normal endometrial lining. If there are symptoms such as abnormal uterine bleeding at the same time, relevant examinations such as hysteroscopy and diagnostic scraping will be needed to determine whether there is endometrial pathology.
After the ultrasound examination, you should inform your doctor of the results and ask him or her to make a comprehensive judgment in light of your own situation, rather than making a diagnosis based on one aspect of the examination alone, in order to avoid delays in treatment.
