Several treatments can shrink uterine fibroids, ranging from prescription medications that cut their size in half within months to minimally invasive procedures and, eventually, the natural hormonal shift of menopause. The right approach depends on the size and location of your fibroids, how severe your symptoms are, and whether you’re planning a future pregnancy.
Hormonal Medications
The most effective medications for shrinking fibroids are GnRH agonists, a class of drugs that temporarily shut down your body’s production of estrogen and progesterone. Without these hormones fueling their growth, fibroids lose volume quickly. Uterine size decreases by roughly 50% after three months on these medications. Doctors often prescribe them before surgery to make fibroids smaller and easier to remove, or as a bridge to menopause for women close to that transition.
The tradeoff is significant. Because GnRH agonists suppress estrogen so dramatically, they trigger menopause-like side effects: hot flashes, bone thinning, mood changes, and vaginal dryness. Most women can only use them for three to six months before the bone loss becomes a concern, and fibroids typically regrow once the medication stops.
A newer category of oral medications, GnRH antagonists, works on the same principle but allows doctors to pair them with small doses of hormones to offset the worst side effects. These are designed for longer-term use and can meaningfully reduce heavy bleeding while modestly shrinking fibroids over time.
Uterine Fibroid Embolization
Uterine fibroid embolization (UFE) is a minimally invasive procedure where a radiologist threads a thin catheter through a blood vessel in the wrist or groin and injects tiny particles into the arteries feeding the fibroids. Cut off from their blood supply, the fibroids gradually die and shrink. According to Duke Radiology, fibroids typically shrink 20 to 50% in the first three months and between 40 and 70% within a year.
Recovery takes about one to two weeks for most women, compared to the four to six weeks typical after surgical removal. UFE treats all fibroids in the uterus at once, which is an advantage if you have multiple growths. The procedure preserves the uterus, though its effects on future fertility are still not fully understood, so it’s generally recommended for women who are done having children or who want to avoid a hysterectomy.
MRI-Guided Focused Ultrasound
This technique uses concentrated sound waves, guided by real-time MRI imaging, to heat and destroy fibroid tissue without any incision. In a study of 80 patients published in the American Journal of Roentgenology, treated fibroids shrank by an average of 31% at six months. That’s more modest than embolization or medication, but the procedure is completely noninvasive. You lie inside an MRI machine for a few hours and can often return to normal activities the next day.
Not everyone qualifies. Fibroids need to be in a location where the ultrasound waves can reach them safely, at least 15 millimeters from the outer surface of the uterus, and not too close to the bowel or other sensitive structures. Very large fibroids or those in awkward positions may not be treatable this way.
What Happens at Menopause
Fibroids are hormone-driven growths, and most women see them shrink as estrogen and progesterone levels drop during and after menopause. The entire uterus decreases in size after menopause, and fibroids generally follow. For women with mild or moderate symptoms who are approaching their late 40s or early 50s, this natural decline sometimes makes aggressive treatment unnecessary.
That said, fibroids don’t always disappear completely. Other tissues in the body besides the ovaries produce small amounts of estrogen, so some fibroids can persist or even continue growing after menopause, though this is less common. If you’re using hormone replacement therapy, that additional estrogen can also keep fibroids from shrinking as expected.
Green Tea Extract and Vitamin D
Among supplements, two have the strongest (though still early) evidence: green tea extract and vitamin D. A clinical trial at a university hospital in Modena, Italy, gave premenopausal women a daily combination of 300 mg of EGCG (the active compound in green tea), vitamin D, and vitamin B6 for 90 days. Fibroid volume decreased by an average of 37% for individual fibroids, and menstrual bleeding shortened by nearly a day per cycle. The effect was most pronounced for fibroids growing within the muscular wall of the uterus.
This is promising but based on a small study of just 16 women with no control group, so the results need to be interpreted cautiously. Larger trials are necessary before these supplements could be considered a reliable treatment. Still, both EGCG and vitamin D have strong safety profiles, and some researchers have suggested daily doses of vitamin D (4,000 IU) and EGCG (800 mg) as a reasonable strategy for women trying to prevent fibroid recurrence after surgical removal.
Diet and Fibroid Growth
No specific food will make an existing fibroid disappear, but dietary patterns do appear to influence whether fibroids grow or stay stable. Diets high in processed foods, refined carbohydrates, added sugars, and unhealthy fats have been linked to increased fibroid risk. These foods cause rapid blood sugar spikes that can disrupt hormonal balance and promote the kind of chronic inflammation that encourages fibroid growth.
On the other side, diets rich in fruits, vegetables, and fiber-rich foods are associated with lower risk. The mechanism likely involves better blood sugar regulation, lower circulating estrogen levels (fiber helps the body clear excess estrogen), and reduced inflammation overall. While dietary changes alone are unlikely to shrink large, symptomatic fibroids, they may help slow growth and complement other treatments.
How These Options Compare
The degree of shrinkage varies widely depending on the approach:
- GnRH agonists: ~50% reduction in 3 months, but temporary unless followed by surgery or menopause
- Uterine fibroid embolization: 40–70% reduction within a year, with lasting results
- MRI-guided focused ultrasound: ~31% average reduction at 6 months, noninvasive but limited eligibility
- Supplements (EGCG + vitamin D): up to 37% reduction in early small trials, needs more research
- Menopause: gradual, variable shrinkage over years as hormones decline
For women with severe symptoms like heavy bleeding, pelvic pressure, or pain, medications and procedures offer the most reliable and substantial relief. For women with smaller or less symptomatic fibroids, a combination of monitoring, dietary adjustments, and possibly supplements may be a reasonable path while waiting to see how the fibroids behave over time.
