Causes Of A Yeast Infection I just started using tampons a few months ago, and I don't have any problems, BUT my best friend said that using tampons gives you yeast infections. I really like to use tampons, but should I stop using them? Not Itchy Yet --- Dear Not Itchy Yet, Keep on using tampons as long as you are comfortable with them. A yeast infection is one of the most common types of vaginal infection. A fungus known as Candida causes it. When there are too many fungi (yeast), this can disrupt the balance of normal bacteria. When this happens in the vagina, it causes an itching, a burning feeling and thick, clumpy discharge that may look like cottage cheese. The vagina and the area around it become irritated and sore. It can even hurt when you urinate. There are multiple causes of a yeast infection. Medications such as antibiotics are a common cause. Illness, diabetes, stress, hormonal changes, birth control pills, and pregnancy are some other reasons they occur. You can get a yeast infection at any age and you don't have to have sexual contact to have one. A yeast infection is not a sexually-transmitted infection (STI). Yeast grows best in a warm, moist environment. This is why it is recommended you wear breathable cotton underwear, avoid tight-fitting pants, and change out of damp bathing suits and leotards as you can. The first time you suspect you have a yeast infection, it is recommended you see your health care provider. Some symptoms of a yeast infection are the same as those for other infections. Checking with your medical professional is important for accurate diagnosis and make sure you are treating the problem correctly.
