Millions Misdiagnosed: SIBO Fears Rise

Experts are raising concerns that millions are misdiagnosed with Irritable Bowel Syndrome (IBS) when they may have Small Intestinal Bacterial Overgrowth (SIBO). This condition involves the rapid multiplication of bacteria in the small intestine, leading to symptoms such as bloating, stomach pain, and diarrhea. These symptoms are frequently mistaken for IBS, hindering access to effective treatments like specific diets and antibiotics. In some cases, patients have been incorrectly told their symptoms are psychological and prescribed antidepressants. SIBO can also lead to serious health risks, including vitamin deficiencies, kidney problems, and an increased risk of pancreatic, bile duct, and colon cancers, according to a 2016 study.

Several factors can contribute to the development of SIBO. Reduced stomach acid, often due to natural causes or the use of common heartburn medications like Proton Pump Inhibitors (PPIs), increases risk. Anatomic abnormalities in the intestines or conditions that slow down the digestive process, such as after a C-section, diabetes, or the use of weight-loss jabs, can also play a role. Even past food poisoning is thought to contribute by slowing digestion. The primary treatment for SIBO is often an antibiotic called rifaximin, though herbal antimicrobials may also be effective. Dietary changes, such as a low FODMAP diet, are typically recommended to starve the bacteria. Addressing underlying causes is crucial for successful management and to restore gut health.
