Final answer:
The term described is menorrhagia, which is excessive bleeding during and between menstrual periods.
Step-by-step explanation:
The term described in the question is excessive bleeding during and between menstrual periods, which is a symptom of a medical condition called menorrhagia. Menorrhagia is characterized by heavy or prolonged menstrual bleeding, and it can be caused by various factors such as hormone imbalance, uterine fibroids, or certain medical conditions.
For example, endometriosis, a condition where the tissue lining the uterus grows outside of the uterus, can cause excessive bleeding during menstruation. Another possible cause is uterine polyps, which are small growths on the lining of the uterus.
If a young woman is experiencing unusually heavy menstrual bleeding for an extended period of time, it is important for her to consult a healthcare professional for diagnosis and appropriate treatment.
