What Are Yeast Infections?

A yeast infection is an overgrowth of a fungus, called candida, that naturally occurs in the body. While candida is normal and healthy in small amounts, it creates uncomfortable symptoms when it multiplies more than it should. The condition can spread and become worse if left untreated. Many factors can contribute to the development of a yeast infection, including antibiotic use, diabetes, being overweight, pregnancy, taking corticosteroids, and having a weakened immune system.

Types

• Yeast infections are classified and treated according to where they occur in the body. The most common types are oral, esophageal, cutaneous (skin) and genital or vaginal yeast infections.

Symptoms

• The most common symptom of yeast infections is pain or itching in the affected area. There may be a rash, which usually appears red if on the skin and white if in the mouth. Vaginal infections often cause a white discharge.

Diagnosis

• A doctor may make a diagnosis based on a visual exam or symptoms, but the only way to know for sure that it's a yeast infection is to have a culture tested in a lab.

Treatment

• Most yeast infections can be easily and quickly treated with antifungal medications. They come in many forms, including creams, pills, suppositories and ointments.

Considerations

• The symptoms of yeast infections are generally non-specific, which means that they can indicate a variety of conditions. For this reason, it is best to see a doctor instead of trying to diagnose and treat a possible yeast infection on your own.
