Taking antibiotics, frequent intercourse, pregnancy and birth control pills also change vaginal conditions and are all associated with an increased risk of infection. For a first time yeast infection, it is important not to self-diagnose and treat, as it may be a sign of an underlying condition. However, if after consulting with a doctor with recurrent yeast infections, you may be able to treat yourself. Some women find that dietary changes help to treat and prevent yeast infections. Research has shown that women who eat a lot of sugar have more yeast infections than those who eat less.
Yeast infections are also more common in diabetic women, who's urine often is higher in sugar.
While a low sugar diet can't hurt, Charles Kawada, Tufts University School of Medicine, does not believe such a diet will cure vaginitis. Yogurt is often thought to help prevent yeast infections. Yogurt containing live cultures of Lactobacillus acidophilus, which are friendly bacteria, help control the growth of yeast in the intestine and, it is thought, in the vagina as well. It is true, however, that a cup of yogurt a day, eaten over time, does enhance your immune system, which in turn can help you prevent infections. Poor diet in general, resulting in a compromised immune system can make you more susceptible to yeast infections.
