A yeast infection, also known as candidiasis, is a common fungal infection that can affect both men and women. It is caused by an overgrowth of the Candida fungus, which is normally present in small amounts in the body. Yeast infections can occur in various areas of the body, including the mouth, throat, skin, and genitals.
Yeast infections can cause a range of symptoms, depending on the location of the infection. Common symptoms include itching, burning, redness, and swelling. In women, yeast infections can also cause vaginal discharge that is thick, white, and clumpy.
