If your periods are heavy enough to leave you drained, breathless climbing stairs, or pale, fibroids may be causing both the bleeding and iron-deficiency anemia behind that fatigue. The good news: it's fixable. Replacing iron treats the anemia, and addressing the bleeding at its source — often without removing the uterus — resolves the underlying problem.
Why fibroids cause such heavy bleeding
Uterine fibroids are one of the most common causes of heavy menstrual bleeding. They tend to bleed for a few overlapping reasons: they can increase the surface area of the uterine cavity, interfere with the muscle's ability to contract and clamp down on bleeding vessels, and change the blood supply and lining of the uterus near the fibroid (modern management of fibroid-related abnormal uterine bleeding). The result is periods that are heavier, longer, or both — soaking through protection quickly, passing large clots, or lasting well beyond a week.
Heavy menstrual bleeding is common in itself, affecting up to a third of women of reproductive age, and fibroids are a frequent culprit (ACOG, Uterine Fibroids). Many women normalize it for years — assuming heavy periods are just their normal — which is exactly why the downstream effect on iron so often goes unrecognized.
How heavy periods lead to anemia and fatigue
Blood carries iron, and iron is what your body uses to make hemoglobin, the molecule in red blood cells that ferries oxygen. When you lose more blood each month than your body can rebuild, your iron stores steadily fall. First comes iron deficiency; if the loss continues, it progresses to iron-deficiency anemia.
This is common in women with heavy bleeding: iron deficiency was present in about half of patients with heavy menstrual bleeding in one guideline review, with roughly half of those also anemic (review of clinical guidelines on iron deficiency and iron-deficiency anemia in women with heavy menstrual bleeding). The symptoms are easy to miss because they build slowly:
- Fatigue and low energy that don't improve with rest
- Breathlessness with ordinary activity, like stairs or walking uphill
- Pale skin, or pale gums and inner eyelids
- Dizziness, headaches, or a racing heartbeat
- Cold hands and feet, brittle nails, or unusual cravings for ice
If you recognize this pattern alongside heavy periods, a simple blood test can confirm whether anemia is present — and it's worth asking for, because heavy or painful periods that cause anemia are a recognized signal that fibroids may need treatment (ACOG, Uterine Fibroids).
Treating both the anemia and the bleeding
Fixing this well means addressing two things at once: rebuilding your iron, and stopping the excess blood loss that depleted it.
Restoring iron. Iron replacement — usually oral iron, or an intravenous infusion when the deficiency is severe or pills aren't tolerated — is used to rebuild iron stores and correct the anemia (iron deficiency guideline review). This is important, but on its own it's only half the job: iron treats the consequence, not the cause.
Reducing the bleeding. For some women, medication is enough to bring bleeding under control. Non-hormonal options such as tranexamic acid and NSAIDs can reduce menstrual blood loss, and hormonal approaches — combined contraceptives, a levonorgestrel intrauterine device, or newer GnRH-based therapies — are also used (modern management of fibroid-related abnormal uterine bleeding). These are reasonable first steps, particularly for milder bleeding.
When bleeding is severe, persistent, or keeps driving your iron back down despite medication, treating the fibroids directly is often what finally resolves it — and that's where a procedure enters the picture.
A uterus-preserving way to stop the bleeding
Historically, the definitive answer to fibroid bleeding was a hysterectomy. It works — but it's major surgery, it's permanent, and it ends fertility. For many women, that's more than they want.
Uterine fibroid embolization (UFE) offers a uterus-preserving alternative. Performed through a pinhole rather than an incision, it shrinks fibroids by blocking the arteries that feed them — which, in turn, reduces the heavy bleeding. It's minimally invasive and typically outpatient, and its evidence base is genuinely strong. In the randomized EMMY trial with 10-year follow-up, quality-of-life improvements after UFE were comparable to hysterectomy and stayed stable over a decade. A Cochrane review found that women who had embolization and women who had surgery were equally likely to be satisfied and had similar quality-of-life improvement, with a shorter hospital stay and faster recovery after embolization.
Being honest about the trade-off: hysterectomy is more definitive because the uterus is gone, and a minority of women need further treatment after UFE over the following years. But for someone who wants to stop the bleeding, keep her uterus, and recover quickly, UFE is a well-studied path that does exactly that — and it leaves surgery available if it's ever needed.
