Yeast infections commonly impact both women and men, taking the form of vaginal and throat infections, called thrush, as well as infections of the penis. Symptoms may include intense itching and burning, a yeasty smell and thick discharge. Over-the-counter treatments, or OTC, exist, although 25 to 30 percent of yeast infections maybe resistant to OTC treatments, requiring antibiotics prescribed by a physician.
Weakened Immune System
Women and men with weakened immune systems often contract yeast infections. According to Penn State Hershey, Milton S. Hershey Medical Center, diseases like diabetes, auto-immune deficiency disorder, or AIDS, or human immunodeficiency virus, or HIV, are commonly behind chronic yeast infections. While yeast infections can be treated, sufferers may need further medical intervention to control the the immune system disorder. Chronic yeast infections without obvious cause may indicate a health problem involving the immune system, so those with recurring infections are urged to visit a physician for full examination and testing.
Sexual Transmission
Sexual contact easily transmits yeast infections. Unprotected sex is not recommended for those susceptible to these infections, as it can be passed back and forth between sexual partners. Even safe sex may contribute to chronic yeast infections, though. Nonoxynol-9, a lubricant and spermicide often found on condoms, may cause yeast infections, as well as latex allergies. To avoid infection, wash hands often, keep sex toys clean and consider using non-latex condoms without nonoxynol-9.
Clothing
Non-cotton, tight, or soiled clothes that trap heat and moisture provide an ideal atmosphere for yeast to grow in women. Wearing tight jeans, pantyhose, wet bathing suits and wet exercise clothes for extended periods of time may cause chronic yeast infections. To cut down on the risk associated with clothing, the Michigan State University website recommends wearing unbleached, undyed, well-washed and completely-dried cotton underwear and breathable clothes.
