Report: Big Pharma Antibiotics can permanently destroy gut flora balance, leading to lifelong illness

Overuse and overprescription of antibiotic drugs has become a widely known culprit in causing the emergence of antibiotic-resistant "superbugs," as well as the onset of digestive and other health problems, caused by the elimination of beneficial gut flora. But a new review published in the journal Nature suggests that such gut flora alterations could be permanent.

Martin Blaser of New York University’s Langone Medical Center argues that antibiotics’ impact on gut bacteria is permanent:
"Early evidence from my lab and others hints that, sometimes, our friendly flora never fully recover. These long-term changes to the beneficial bacteria within people’s bodies may even increase our susceptibility to infections and disease. Overuse of antibiotics could be fuelling the dramatic increase in conditions such as obesity, type 1 diabetes, inflammatory bowel disease, allergies and asthma, which have more than doubled in many populations." Among the findings he cites in support: The population-level observation that the incidence of infection with H. pylori, the bacterial cause of gastric ulcers, has declined over decades just as the incidence of esophageal cancer has risen. In addition, he offers his own research group’s observation that children who don’t acquire H. pylori are at greater risk of developing allergy and asthma, and their findings that eradicating H. pylori affects the production of the two hormones, ghrelin and leptin, that play a role in weight gain.
