ABSTRACT
Heavy menstrual bleeding (HMB), also known as menorrhagia, refers to excessive menstrual flow whereby the patient is free from bleeding during the intermenstrual period. The terms irregular uterine bleeding and intermenstrual bleeding are used for bleeding that occurs between periods; this condition is also called metrorrhagia. HMB is an important symptom of many well-defined conditions, which may or may not be associated with irregular cycles. As a rule, delayed menstruation is often associated with an increase in the menstrual blood flow. These terms are limited to patients who menstruate and must not be used for bleeding after the menopause.
