Men, women, children and the elderly, anyone and everyone can suffer from a yeast infection, which is caused by the overgrowth of a fungus that already lives on us called Candida, which is where the alternative name Candidiasis comes from. There are several species of Candida but the one you may be most familiar with is Candida albicans. A yeast infection can happen anywhere on the body, though it is true a vaginal yeast infection is the most common form because the vagina is such a perfect breeding ground, it can also occur under folds of skin, in the mouth, on the penis and so on. Treatments are out there that are both natural, effective and safe, alternatives to conventional drugs people are becoming disenchanted with.
