Why is My Period so Heavy with Large Clots?

Heavy periods with large clots typically indicate excessive menstrual bleeding, medically known as menorrhagia. Normal menstrual flow is about 30-35ml per cycle, but heavy bleeding can exceed 80ml and include clots larger than a quarter. Common causes include hormonal imbalances, uterine fibroids, endometriosis, polyps, or blood clotting disorders. Thyroid dysfunction and certain medications can also contribute to heavy flow. The large clots form when blood pools in the uterus before being expelled, allowing natural anticoagulants to become overwhelmed. If you're changing tampons or pads every hour for several consecutive hours, or clots are consistently larger than a quarter, consult a healthcare provider for proper evaluation and treatment options.
