About antibiotics



Antibiotics in early life are associated with subsequent irritable bowel syndrome (IBS) and food hypersensitivity, as well as altered tryptophan metabolism and synthesis that is now being further aggravated by widespread use of glyphosate.

Antibiotic exposure in mothers interferes with the gut flora that they pass on to their offspring and can have long-term health consequences, including leading to worse outcomes for diseases such as colitis.

Infant exposure to antibiotics during vaginal labor delays maturation of their gut bacteria—and longer exposure to antibiotics worsens the delays.
