Under normal circumstances, the diagnosis of endometrial polyps is usually determined clearly by performing an ultrasound at the hospital. Normally, the endometrial line is continuous. There is a specific thickness to the endometrium. Typically, a thickness of 3-4mm in the endometrium at the end of menstruation is considered normal. During ovulation, the thickness of the endometrium is 8mm. Before menstruation starts, the endometrial thickness is generally more than 10mm. If it is within this range, it is generally considered normal. If there is an increase in endometrial thickness and the echo of the endometrium is not continuous, and the endometrial echo is uneven, in most cases, endometrial polyps are suspected. The diagnosis of endometrial polyps can generally be clearly determined through color Doppler ultrasound. This diagnosis is not difficult. Once endometrial polyps are clearly diagnosed by ultrasound, they can be removed by hysteroscopic polypectomy at the hospital.
