Disease description:

A woman's menstruation also reflects her health status. During the menstrual period, one can observe the color, cycle, and flow of the menstrual blood to understand her physical condition. For example, excessively heavy or light menstrual flow is abnormal. So, what causes an unusually heavy menstrual flow, and why are there blood clots?

Heavy menstrual bleeding with blood clots differs from normal menstruation. First, it is important to check whether the patient is pregnant. For example, if the patient is pregnant and experiences a miscarriage, these symptoms may occur, which can be confirmed through a urine pregnancy test or blood hCG test. If pregnancy is ruled out, a pelvic color Doppler ultrasound should be performed to check for uterine fibroids, adenomyosis, or endometrial polyps, as these conditions may cause menstrual abnormalities. If any of these conditions are identified, appropriate treatment—possibly including surgical intervention—should be provided based on the specific clinical situation.
