Step-by-step explanation:
Excessive uterine bleeding occurring both during menses and at irregular intervals is called Metrorrhagia. Metrorrhagia is characterized by abnormal bleeding that can happen in between regular menstrual periods or in addition to the regular menstrual flow. It can be caused by various underlying conditions such as hormonal imbalances, uterine fibroids, or ovarian cysts.
For example, if a person experiences heavy bleeding during their menstrual period and then also has episodes of bleeding at other times during the month, it can be classified as metrorrhagia.
