A yeast infection, also known as candidiasis, is an infection caused by the overgrowth of a type of fungus called Candida. This fungus is normally present in small amounts on the skin and inside the body, but sometimes it can grow out of control and cause symptoms such as itching, burning, redness or irritation.
There are several types of yeast infections, including vaginal yeast infections (also known as vulvovaginitis), oral thrush, diaper rash, and athlete's foot. These infections can be caused by various factors such as antibiotic use, stress, poor hygiene, or an imbalance of the body's natural bacteria and yeast.
Treatment for a yeast infection typically involves using anti-fungal medications to kill the excess Candida and restore balance to the body. In some cases, lifestyle changes such as maintaining good hygiene or managing stress may also be recommended.
