Candida is a yeast that is found in the vagina and intestinal tract of humans. In most cases, Candida does not cause infections. However if the natural balance of good bacteria and bad bacteria is disrupted, candida overgrowth can occur and begin to cause many types of infections and conditions. Many factors can play a role in causing candida overgrowth such as use of antibiotics, diabetes, a weakened immune system, and many more factors. It is even known to be caused by a poor diet, or a diet that is too rich in yeast containing products. Once a candidal infection is allowed to occur, correcting the balance of candida can be very difficult to correct. In fact, a special diet called "The Candida Diet" may even be necessary. A few steps can be taken to prevent Candida overgrowth, such as taking a Probiotic, whenever you are prescribed antibiotics.
