Why do uterine fibroids cause bleeding between periods?

Bleeding Between Periods is a common presentation of Uterine Fibroids. Fibroids are non-cancerous growths made of uterine muscle and fibrous tissue. A fibroid that projects into the cavity can make the lining uneven or more prone to bleeding. Fibroids may also interfere with the uterus tightening effectively, which can prolong or restart bleeding.

Spotting may appear between otherwise expected periods, after sex, or alongside heavier or longer menstrual bleeding. The amount and timing can vary with the fibroid's size, position, and relationship to the uterine cavity. Other causes, including pregnancy-related changes, infection, polyps, or hormonal changes, can also cause this symptom.

Book a medical assessment if bleeding between periods is new, recurring, or affecting daily activities. Note when it occurs, how long it lasts, whether it follows sex, and whether you have pain, pressure, or heavier menstrual flow. A clinician may review your history, perform an examination, and arrange pelvic imaging to assess the uterus and fibroids.

Care depends on the bleeding, fibroid location, symptoms, pregnancy plans, and other health factors. Options may include observation, medicines to reduce bleeding or pain, or a procedure to treat a fibroid. Treatment for iron deficiency may be considered if ongoing blood loss has lowered iron stores.

Seek urgent help if bleeding is rapidly soaking through pads, or if it comes with fainting, severe weakness, shortness of breath, chest discomfort, or intense pelvic pain. Get prompt advice for bleeding during pregnancy, after menopause, or with fever or foul-smelling discharge.

Ask where the fibroid is located, whether it changes the uterine cavity, and whether another cause of bleeding needs to be checked. You can also ask which treatment fits your bleeding pattern and pregnancy plans, and how to monitor iron levels if bleeding continues.
