I'm afraid I'm starting to go through the same thing again. Only about 10 days ago I posted on another thread that I hadn't had a bacterial infection in a year. A few days later I was diagnosed with one. (I think bragging like that was just tempting fate!) Previously, I would yo-yo back and forth between yeast and bacteria. The medicine (cream or pills) for BV CAUSES yeast by killing lactobacillus along with the bad bacteria. It can even cause rebound BV. (After the medicine is discontinued there is an 80% "reinfection" rate.) This is because Lactobacillus secrete lactic acid, which lowers pH, making the environment inhospitable to bacteria. In light of the recent controversy on this BB I hate to bring this up, but my gyno said that unprotected you-know-what has the opposite effect. You don't "catch" germs or yeast from your partner, he just raises your pH, making you more susceptible. If you have IBS D, it complicates the picture, both through irritation and possible contamination with both yeast and bacteria. I'm 46, and the gyno said hormone depletion is also a causative factor. I'm going to try BC pills to see if they help. Taking lots of acidophilus supplements (or eating yogurt, if you can) is also supposed to be helpful.[This message has been edited by zigmissus (edited 07-18-2000).]
