Antibiotics affect gut flora because gut flora is very similar to the bacteria that antibiotics treat. One week of treatment can result in yeast overgrowth. In addition to the expansion of less beneficial bacteria population. Such as Clostridium difficile which can cause a deadly type of diarrhea when it gets out of control.
Antibiotics negatively impact the healthy bacterial population, which in turn increases the population of bacteria that resists antibiotics. Therefore, a continuous source of infection will always be present.
For instance, have you ever taken antibiotic for a urinary tract infection to have the infection again a few weeks later?
Unfortunately, the effect can last up to two years even after you stop taking antibiotics.
Antibiotics courses should be fully completed.
When you only take a part of the antibiotic course, this increases the count of resistive bad bacteria that crowds out the good bacteria. And then leads to more infections that can be progressively harder to treat. “what doesn’t kill you makes you stronger” is actually true for bacteria if you don’t take the full antibiotic course to completely kill the bad bacteria. The remaining bacteria will grow more resistant. And harder to treat and will overcome the good healthy bacteria in your body.
We are not the only species that consume antibiotics and affect gut flora. Commercially raised chicken, cattle, and pigs take an array of antibiotics. These antibiotics enter our bodies when we consume these meats. This is why it is important to only eat pasture-raised meat and organic chicken. They don’t have antibiotics in their bodies that can pass on to our bodies.
