Studies have shown that persons with blood sugar imbalances are more likely to develop yeast infections, so diabetics are especially prone, as are hypoglycemics. Tight or restrictive clothing such as nylon or leather can trap moisture and cause yeast to overgrow. Too vigorous scrubbing or using antibacterial or perfumed soap in the vaginal area may also contribute. An imbalance of chemicals in your body, such as those associated with birth control pills, hormones, or even pregnancy, can result in yeast infection. In the U. S., the most common offender, however, is use of antibiotics, which kill the natural bacteria in the vagina, allowing the yeast to grow out of control.
Dietary adjustments can sometimes help prevent recurring yeast infections.
Common foods that may contribute to yeast vaginitis include aged cheeses, mushrooms, bakery products, beer, caffeine and artificial sweeteners. Foods that may help prevent yeast vaginitis include yogurt and acidophilus. Your doctor may, in fact, recommend applying plain yogurt directly to the affected area, which may sound strange, but can be very soothing and actually improve the acid balance of the vaginal area. Whether you are eating yogurt or applying it directly, be sure that the yogurt you choose is clearly marked to contain live and active yogurt cultures including L acidophilus. Wearing loose clothing and white, cotton panties are also good preventative measures.
