Stress, Vitamin D Deficiency and Fibroid Risk: What You Need to Know

Posted on August 25, 2025

What do stress, vitamin d deficiency and fibroids have in common? Well, they can all affect your period! And those first two increase your risk for the third item listed!

Here's the deal: stress and vitamin d deficiency may increase your fibroid risk and impact your periods. In a minute, we’ll explore these ideas further. First, however, we’ll give you a quick fibroid overview so we’re all on the same page.

What are fibroids?

Female with Fibroids

Fibroid tumors are firm, muscular, uterine growths. We classify (and name them) based on their location in or on your uterus. If they’re inside your uterus, they’re called submucosal. When they grow on your outer uterine surface, they’re subserosal. Fibroids in the muscles of your uterine wall are intramural, and fibroids that grow like stalks outside your uterus are pedunculated.

Fibroids also vary widely in size. Some are so small that they go undetected, or cause no symptoms. But others are much larger, and the can also develop in groups. When this happens, you may experience pain, heavy periods, anemia, pregnancy complications or even infertility.

Vitamin D Deficiency and Other Risks: Why do Fibroids Develop?

Unfortunately, we don’t truly know what causes fibroid development. But we do know they impact black women more than any other group.

Lots of things affect your fibroid risk. Current research suggests that a history of stress and depression increases your risk for heavy menstrual bleeding. Plus, stress may be associated with an increased fibroid risk, as this study found that women with elevated stress levels also had more potentially tumor-causing mRNA detectable in their uterine tissue. Research also suggests that vitamin d deficiency could increase your risk for fibroids. When working properly, your body's vitamin d stores produce an anti-fibroid effect by reducing certain chemicals that seem to trigger fibroid growth. This factor, in addition to family history and exposure to the chemicals within hair relaxers, could help explain why black women more often get fibroids. Because, vitamin d deficiency is 10 time more prevalent in Black women than in white women!

Recently, researchers discovered a new risk factor for fibroids: remaining sedentary for 6 or more hours each day! And, while all women's risk for fibroids increased with more sedentary time, one group was most impacted. Specifically, the fibroid risk for women in perimenopause (the transition period between regular menstruation and menopause) is most impacted by remaining sedentary.

In combination, each of these factors can help you understand your fibroid risk, and could determine your next best steps.
