Theoretically. Antibiotics lead to yeast overgrowth simply because they take away candida’s competition and let it run wild. The gut flora plays a key role in immunity too, and probably helps keep it in check in other ways. Reversing the damage is more complicated though. For one, restoring gut flora isn’t easily accomplished. You need 150 or so species for a healthy gut, and they don’t just reappear if they’re wiped out. They need to be eaten or obtained by contact with healthy people or animals.
Changes in your immune system can make candida essentially immune to your defences too. Jorge’s theory is that killing enough of it allows your immune system to recover itself. This could partly be because it allows your gut flora to regenerate and begin regulating immune processes again. Whichever way you look at it, you need to kill candida and restore gut flora to beat this filthy yeast. It’s tough and takes a lot of time and commitment, but I think you’ll learn a lot about your body and how to be healthy in the process, so stay positive and keep fighting.
