Candida is a type of yeast that naturally lives in the human body, particularly in areas like the mouth, gut, and skin. Under normal circumstances, it coexists peacefully with other microorganisms. However, when the balance of these microorganisms is disrupted, Candida can overgrow, leading to infections. One common infection caused by Candida is known as candidiasis, which can affect various parts of the body, including the mouth (oral thrush) and the genital area (yeast infection). Factors such as a weakened immune system, antibiotics, and diabetes can increase the risk of Candida overgrowth.
