Candida albicans is a type of yeast that naturally lives in our bodies, particularly in the mouth, gut, and on the skin. While it usually doesn't cause any problems, it can grow too much under certain conditions, leading to infections. This is more common in people with weakened immune systems or those taking antibiotics, which can disrupt the balance of bacteria in the body. When Candida albicans overgrows, it can cause various health issues, such as oral thrush or yeast infections. Symptoms may include itching, discomfort, and a white coating in the mouth. Maintaining a healthy lifestyle can help keep this yeast in check and prevent infections.
