Prolonged menstrual bleeding, also known as menorrhagia, is a common disorder among people who menstruate. It refers to bleeding lasting longer than seven days and involves more blood flow than is typical during menstruation. There are several possible causes of menorrhagia, including:

• Hormone problems: Hormonal imbalances, such as those caused by thyroid problems or polycystic ovary syndrome (PCOS), can cause heavy bleeding.

• Uterine-related problems: Fibroids, polyps, adenomyosis, and cancer of the uterus or cervix can cause heavy or prolonged menstrual bleeding.

• Bleeding disorders: Certain bleeding disorders, such as von Willebrand disease, can cause heavy menstrual bleeding.

• Medications: Some medications, such as hormonal birth control or blood thinners, can cause heavy or prolonged menstrual bleeding.

• Other health conditions: Kidney or liver disease, and some cancers, can also cause heavy menstrual bleeding.

If you experience heavy menstrual bleeding, it is important to see a healthcare provider to determine the underlying cause and receive appropriate treatment. Untreated heavy or prolonged bleeding can lead to anemia and other health problems. Treatment options may include hormonal medications, procedures to treat the uterine lining, or removal of the uterus.
