Heavy menstrual bleeding, also known as menorrhagia, can be caused by a variety of factors. Some of the most common causes include:

• Hormonal imbalances: The hormones that your body produces, like estrogen and progesterone, help regulate your menstrual cycle, including how heavy your periods are. Having a condition that causes your hormones to become imbalanced can lead to heavy period bleeding.

• Uterine problems: Fibroids, polyps, adenomyosis, endometrial hyperplasia, and endometrial cancer are all conditions that can cause heavy menstrual bleeding.

• Medications: Certain medications, such as blood thinners, hormonal medicines like birth control pills that have estrogen and progestin, and medicines that prevent blood clots, can result in heavy or lengthy menstrual bleeding.

• Bleeding disorders: Women who have bleeding disorders, such as Von Willebrands disease, may experience heavy menstrual bleeding.

• Other factors: Other factors that can contribute to heavy menstrual bleeding include pregnancy complications, ectopic pregnancy, miscarriage, liver or kidney conditions, and stress.

If you experience heavy menstrual bleeding, it is important to talk to your doctor to determine the underlying cause and find an appropriate treatment. Some treatments may include medications, hormonal therapies, or surgery.
