The reason the antibiotics cause yeast or Candida problems is because it kills the beneficial bacteria along with the bad bacteria. An abundance of beneficial bacteria normally signifies a well-working immune system, and these two positives will prevent yeast from turning into a fungal form. If you have to take an antibiotic, ask the doctor if Ampicillin will work for your infection as the Candida is less likely to be as bad with this antibiotic. But even with Ampicillin you will need to go back on the Candida diet if you’re not already. Also, you should purchase a high count and strain of a good probiotic and begin taking it before starting the antibiotic. A good one is Ultimate Flora Critical Colon BifidoMAX 80 Billion 14-Strain Probiotic.
