Fibroids can be shrunk through non-surgical means for women who wish to retain their fertility and do not want to undergo surgery.
Hormone medication to shrink fibroids
Hormones may be given in several forms. The female hormone progesterone, that counteracts excess oestrogen, may be given by tablet, injection, implant or intrauterine device.
More commonly drugs called gonadotrophin-releasing hormone agonists (GnRHa) are injected on a monthly or three monthly basis. GnRHa create a temporary menopause by switching off oestrogen production and causing the fibroids to shrink. They can also cause temporary menopause symptoms like hot flushes and tiredness.
GnRHa are generally used as a temporary measure over three to six months to:
Other medications like painkillers may be tried to reduce discomfort. Tranexamic acid or low dose birth control pills may reduce bleeding problems without causing the fibroids to grow.
Uterine artery embolisation (UAE)
UAE is a procedure carried out by specialist x-ray doctors. From the groin, they can inject microscopic particles to block the blood vessels supplying the fibroids. This can cause them to shrink by more than half in many cases. As a result, the symptoms caused by the fibroids improve or disappear.
UAE is a well-proven, low-risk alternative to removing fibroids for women who do not wish to have surgery. There have also been many successful pregnancies following UAE. However, for women who wish to retain their fertility, use of UAE needs to be carefully discussed with a gynaecologist experienced in the management of fibroids.
MRI focussed ultrasound shrinkage of fibroids has a similar effect to UAE but is not offered in many centres at present.
All forms of removal or shrinkage carry a significant risk that fibroids will recur at a later date unless the natural menopause occurs soon after treatment.

Summary on uterine fibroids
Fibroids often exist without any symptoms and, once diagnosed, may not require any treatment. However if you have significant symptoms, seeing a gynaecologist early may give you more treatment options. Ultimately, hysterectomy is the only complete cure for fibroids.
