Candida, a type of fungi, causes anal yeast infection (Perianal Candidiasis). It normally lives in the body, particularly on the skin’s surface, in the digestive tract, and the vagina. When Candida multiplies uncontrollably in the anus, an anal yeast infection may set in.
It’s important to note that yeast infections can happen anywhere in the body when there’s an overgrowth of the Candida yeast, which thrives in warm, moist places. A woman can also develop yeast infections in her mouth (oral thrush), throat, breast, and vagina.
Please note that even though yeast infections can occur in the genital areas, it’s not considered a sexually-transmitted disease. This is because a lot of factors can cause Candida overgrowth.
These factors include wearing tight-fitting clothes, antibiotic use, stress, and conditions like pregnancy and diabetes. However, anal yeast infection can spread through sex, so doctors encourage patients to refrain from engaging in sexual activities until the end of recovery.
