(Fibroids; Leiomyoma; Myoma; Fibromyoma)
Fibroids are noncancerous growths in the wall of the uterus (womb). These common growths may be as small as a seed or as large as a melon. A woman may have one or many. Most fibroids stay inside the uterus. Others may extend and affect nearby organs.
The cause of fibroids is not known. Genetics may play a role.
Fibroid growth is stimulated by estrogen and progesterone hormones. This causes fibroids to grow during pregnancy and shrink after childbirth. It also causes them to become less of a problem after menopause.
The risk of fibroids increases in women until the start of menopause. Other things that may raise the risk are:
- Never having children
- Early menstruation (periods)
- Periods that happen more often than normal
- Painful periods
- Having other family members with this problem
Some women may not have symptoms. Others may have mild to severe problems. It depends on the size and location of the fibroids. Problems may be:
- Pelvic pain or pressure
- Belly swelling
- Heavy menstrual bleeding
- Blood clots in menstrual flow
- Periods that last longer than normal
- Bleeding between periods
- Cramping during periods
- Pain during sex
- Frequent need to urinate
- Low back or leg pain

- Tranexamic acid to control heavy bleeding
Women who are not helped by these methods and who are not planning to become pregnant may need treatment, such as:
