When suspecting endometritis in women, the first step is to inquire about the medical history. Most women exhibit abnormalities in their menstrual cycle, and some only show changes in the amount of menstruation. Ultrasound examination of the reproductive system shows no organic lesions, and the hormone panel is normal. During a gynecological examination, tenderness in the uterine body may be observed. Sometimes, ultrasound examination suggests that the endometrium is thin and uneven. Performing a hysteroscopy, localized hyperemia and edema of the endometrium can be seen, and diagnostic curettage plays a certain role in diagnosis.
