Menorrhagia is a condition characterized by abnormally heavy and prolonged uterine bleeding during menstruation. It is a common gynecological condition and affects up to 20% of women of reproductive age. Symptoms may include heavy menstrual bleeding lasting for more than 7 days, the need to change sanitary protection more frequently, flooding between periods and the passing of large blood clots. The cause of menorrhagia is not always known, but can be due to hormonal imbalances, structural abnormalities of the uterus, or other medical conditions such as thyroid disease, liver disease and bleeding disorders. It can also be caused by taking certain medications such as anticoagulants or non-steroidal anti-inflammatory drugs (NSAIDs). Management of menorrhagia depends on the underlying cause, but can include medications such as hormonal contraceptives or non-steroidal anti-inflammatory drugs (NSAIDs). Other treatments such as endometrial ablation or surgery may also be recommended if the bleeding is severe or persistent. In some cases, lifestyle modifications such as limiting alcohol intake and avoiding smoking can also help to reduce heavy menstrual bleeding.
