How long does uterine artery embolisation take to work for uterine fibroids?

A catheter delivers small particles into the uterine arteries to reduce blood flow feeding the fibroids. The fibroids then shrink or become less active over time. Heavy bleeding, pelvic pressure, frequent urination or pain may therefore improve at different speeds.

Pain and cramping can occur soon after the procedure and do not mean the treatment has failed. Early discomfort reflects the body’s response and is separate from the later change in fibroid-related symptoms. The response depends on fibroid size, location, number and your general health.

Take prescribed medicines as directed, protect the catheter entry site as instructed and pace activity during recovery. Keep a record of bleeding, pain, pressure and urinary symptoms so you can describe trends at review.

Attend planned follow-up even if symptoms improve. Your clinician may use examination or imaging to assess the uterus and discuss whether additional care is appropriate. Ask before restarting strenuous exercise, driving or other activities if you are unsure.

Contact the treating service urgently for severe or increasing pain, heavy bleeding, persistent vomiting, continuing fever, foul-smelling discharge, fainting, breathing symptoms or a painful swollen leg. Get advice promptly for worsening redness, swelling or bleeding where the catheter entered.

Ask which fibroid symptoms are expected to change first, when imaging or review will assess shrinkage, how to manage cramping, and what the next option would be if bleeding or pressure persists.
