Yeast infection

Overview of yeast infection

Yeast infections occur when an overgrowth of Candida yeast in the vagina triggers uncomfortable symptoms. Vaginal yeast infections are very common – nearly 75 percent of all women have experienced at least one in their lives.

Symptoms of yeast infection

Signs and symptoms of a yeast infection include:

• A burning sensation, especially when urinating or having intercourse
• Swollen, red outer genitalia (vulva)
• Vaginal pain and soreness
• Watery vaginal discharge
• Thick, whitish vaginal discharge

Causes of yeast infection

Many things can trigger the yeast overgrowth that causes a yeast infection, including:

• Pregnancy
• A weakened immune system from diseases, such as HIV, and medical treatments, including chemotherapy
• Uncontrolled diabetes
• Antibiotic use, which can fight a bacterial infection, but can kill the "good" bacteria that help keep yeast in check
• Corticosteroids, which can depress the immune system and make you more likely to develop infections, including a yeast infection
• Hormone supplement or contraceptive pill use, which creates a high-estrogen environment where yeast thrives
• Natural hormonal swings (such as those that occur during puberty, pregnancy, and perimenopause)
