Gut health and the troubles caused by antibiotic use.

Dr. Rosedale prescribes antibiotics only when they must be used, and often in conjunction with a Nystatin to combat an overgrowth of yeast.

Andreanna Rainville, RN, LMP stated it very well below;

Antibiotics including Sulfa drugs.
Antibiotics kill all bacteria. They do not distinguish good bacteria from bad. Antibiotics kill the "good" flora which normally keeps the Candida under control. This allows for the unchecked growth of Candida in the intestinal tract. It is normally difficult to recover a yeast culture from bodily surfaces. However, after 48 hours of taking tetracycline, yeast can be cultured easily from anyone.

The prevalence today of Candida may be most directly related to the widespread societal exposure to antibiotics -- from prescriptions for colds, infections, acne, and from additional consumption of antibiotic-treated foods such as meats, dairy, poultry and eggs.

Notably, antibiotics do not kill viruses; they only destroy bacteria. Yet, they are universally prescribed for colds, flu and other viral problems. Such indiscriminate and extensive use of antibiotics is not only considered a primary cause of Candida overgrowth, but is recently being found to be responsible for the unbridled development of "super bacteria."
