Yeast Infections
Ok This may sound stupid.........
BUT
If you are having sex then your parter may be "contaminated" and you keep passing the yeast infection back and fourth.
ALSO with thrush you ALSO NEED to get a new tooth brush. The Yeast infection can stay on the old tooth brush.
Persistent and Systemic Yeast
SEE: http://www.fwhc.org/health/yeast.htm
Some women are prone to yeast conditions and get them frequently. These women may want to pay attention to precipitating factors, which can vary from person to person. Some things which commonly cause or worsen yeast overgrowth are stress, sudden diet and weather changes, birth control pills, use of the contraceptive sponge, and most commonly, a high sugar, carbohydrate, caffeine, or yeast diet. Frequent douching can increase yeast problems. Some health conditions, such as pregnancy and diabetes, can instigate an overgrowth.
Perhaps the biggest contributing factor in the creation of yeast overgrowth, however, is the use, and overuse, of antibiotics. Although designed to kill "bad" bacteria (those that make us ill) antibiotics, to varying degrees, kill "beneficial" bacteria (those that keep us well, such as the digestive bacteria in our intestines.) Any use of antibiotics will kill off some good bacteria and prolonged and overly aggressive use of antibiotics can cause systemic problems for both men and women. When the balance of good and bad bacteria is thrown off, yeast can build up in the intestines and cause a whole host of health problems. Whenever you take antibiotics, keep in mind this is strong medication. Ask your provider: How does it work? Is there a topical antibiotic I could use instead? Sometimes, antibiotics are needed but their overuse can cause serious problems. Adding acidophilus and bifidus to your diet (in capsules) can re-balance the intestinal bacteria, and build up resistance to future overgrowths.
Women experiencing persistent vaginal yeast overgrowth who are using a cervical cap or diaphragm, need to wash and dry it well after use. Some women have found relief from tenacious conditions with the "sucking air" method of douching. In a bathtub, a woman can insert yogurt, vinegar or other remedy. Lying on her back, hands at her side and palms down, she can bring her feet back over her head. This action causes the vagina to balloon out and pulls the vinegar or yogurt all the way in to fill the vagina and get every fold of skin.
Systemic yeast is a system-wide infection/overgrowth throughout the body. It requires dramatic changes in diet and long-term attention to avoiding things that encourage yeast to grow.
Hope this helps
Unfortunately, this is a side effect from using antibiotics. I have had several surgeries not related to obesity and the antibiotics they put you on kills your good bacteria along with the bad which makes you prone to a yeast infection. I am just coming off of a very strong antibiotic and a yeast infection. If you are not currently on an antibiotic, I would try a natural remedy from the health food store along with monistat first which usually entails replacing the good bacteria (acidophilus).
