Uterine Fibroids (cont.)

Uterine Fibroid Causes

The exact reasons why some women develop fibroids are unknown. Fibroids tend to run in families, and affected women often have a family history of fibroids. Women of African descent are two to three times more likely to develop fibroids than women of other races.

Fibroids grow in response to stimulation by the hormone estrogen, produced naturally in the body. These growths can show up as early as age 20 and shrink after menopause when the body stops producing large amounts of estrogen.

Fibroids can be tiny and cause no problems, but they also can grow to weigh several pounds. Fibroids grow slowly.

The following factors have been associated with the presence of fibroids:

  • Being overweight, obesity

  • Never having given birth to a child (called nulliparity)

  • Onset of the menstrual period prior to age 10

  • African American heritage (occurring 3-9 times more often than in Caucasian women)
