Candida
Candida is a type of fungus that naturally exists in the body. The most common type is Candida albicans. Candida typically resides in the mouth, intestines, and vagina, and it is part of the body's normal microbiota.
However, the overgrowth of Candida can lead to infections. This can occur if there is a change in the body's environment, such as a weakened immune system, or if there is an imbalance in the body's microbiota, such as due to the use of antibiotics or steroids. Candida infections can affect various parts of the body, including the mouth, skin, nails, intestines, and genitals. Symptoms of a Candida infection may include itching, soreness, burning, and redness.
