Food Poisoning & Medically Induced Causes

Food poisoning is a major but often overlooked trigger for SIBO. When harmful bacteria that cause food poisoning (including E. coli or Salmonella) release toxins, they can damage the migrating motor complex (MMC)—the system responsible for clearing bacteria from the small intestine. If this function is impaired, bacteria accumulate and cause long-term digestive issues. Additionally, some medications can alter gut motility or microbiome balance, further increasing the risk.
