Hi Marion. Horrible, isn't it?
If you get recurrent thrush, it might be worth a trip to see your GP or, if you prefer, the genitourinary medicine department (they're really good, and not just there for sexually transmitted infections, which thrush, of course, isn't). Three reasons:
1. To have swabs taken to make sure it IS thrush.
2. To have a fingerprick blood glucose test. Sometimes (rarely!) recurrent thrush is the presenting sign for diabetes.
3. To get treatment that can deal with the more uncommon variants of the yeast that causes thrush. Sporanox (oral capsules) or nystatin (pessaries) are the best options, but need to be prescribed.
Self-help: Probiotics may help. As SP says, throw out the bath cosmetics - shower if you can, and use plain water or unscented soap "down there". Wear breathable undies and give them an extra rinse after washing them. And if you have a partner, get him to use anti-thrush cream (externally is fine) two or three times a day for a few days.
Changing your contraception to depo-provera (the injection) seems to sort out recurrent thrush - nobody is quite sure how. A low-sugar diet may help. Avoiding yeast in foods doesn't, because the yeast in bread and the yeast that causes thrush are not related.
Whatever you do, one day it will just stop recurring. I promise :-)
