Which symptom is commonly associated with endometriosis?

Heavy or prolonged menstrual flow is commonly associated with endometriosis due to the hormonal imbalances and inflammatory responses that occur within the body as a result of the condition. In endometriosis, tissue similar to the lining of the uterus grows outside of the uterus, which can lead to pain and heavy bleeding during menstruation. This happens because the ectopic endometrial tissue also responds to hormonal signals, thickening and shedding, which can result in excessive bleeding.

It is not unusual for individuals with endometriosis to report heavier periods, known as menorrhagia, often accompanied by severe cramping and discomfort. This symptom can significantly impact quality of life and may lead to further medical evaluations. Thus, heavy or prolonged menstrual flow is a classic indicator for clinicians when assessing a patient for potential endometriosis.
