Risk factors

There are few known risk factors for uterine fibroids, other than being a woman of reproductive age. Factors that can have an impact on fibroid development include:

• Race. Although all women of reproductive age could develop fibroids, black women are more likely to have fibroids than are women of other racial groups. In addition, black women have fibroids at younger ages, and they're also likely to have more or larger fibroids, along with more-severe symptoms.
• Heredity. If your mother or sister had fibroids, you're at increased risk of developing them.
• Other factors. Starting your period at an early age; obesity; a vitamin D deficiency; having a diet higher in red meat and lower in green vegetables, fruit and dairy; and drinking alcohol, including beer, appear to increase your risk of developing fibroids.
