Risk factors
By Mayo Clinic staffAmong the things that increase your risk of developing a yeast infection are:
- Antibiotic use. Yeast infections are common in women who take antibiotics. Broad-spectrum antibiotics kill healthy bacteria in your vagina, which can lead to the overgrowth of yeast.
- Increased estrogen levels. Yeast infections appear to occur more frequently in women with increased estrogen levels, for instance, in women who are pregnant, those taking high-dose estrogen birth control pills or those taking estrogen hormone therapy.
- Uncontrolled diabetes. In women who have diabetes, those with poorly controlled blood sugar levels are more likely to develop yeast infections than are women who have diabetes under control.
- Impaired immune system. In women who are immunocompromised — such as by corticosteroid therapy or by HIV infection — yeast infections are more likely to occur.
- Being sexually active. Although yeast infections aren't considered sexually transmitted diseases, one way the candida organism can be introduced into your vagina is through sexual contact.
