Eva B. Cwynar, MD

Internal Medicine

Candida, an overgrowth of a yeastlike fungus that may thrive in the intestinal tract, mouth, skin, and vagina, can be caused by long-term antibiotic use, too much alcohol, and chronic stress, which suppresses the immune system. In fact, any time you are ill, your immune system is temporarily compromised, and candida can easily take the opportunity to proliferate.

Vaginal yeast infection is the most common yeast infection. Men can get yeast infections too, and people with diabetes or compromised immune systems may also get yeast infections. Some are not genital infections, but can affect the mouth or other parts of the body. Treatment is either a topical application or an oral medication.
