Endometritis can be detected through the following methods:

First, gynecological examinations, as most patients with endometritis experience lower abdominal pain. During the gynecological examination, the doctor can detect tenderness in the uterus, and severe patients may exhibit pain upon movement.

Second, undergoing an ultrasound examination, where heterogeneous uterine lining echoes can be found. This condition should be considered as a manifestation of endometritis.

The third method is to perform diagnostic curettage, and then examine the scraped tissue pathologically. If inflammatory cells are found, endometritis can be definitively diagnosed.
