SIBO (Small Intestinal Bacterial Overgrowth) is now understood to be the underlying cause of up to 80% of IBS cases and many other digestive disorders. Beyond gut symptoms like bloating and gas, bacterial overgrowth in the small intestine can contribute to health challenges, including cognitive dysfunction, autoimmune conditions, fatty liver disease, and cardiovascular problems, affecting patients who may not realize their symptoms are connected to gut health.

In this episode, Dr. Jill Carnahan explains the three main types of SIBO, testing methods, and treatment options. She discusses the role of fungal overgrowth, mast cell activation, and tick-borne infections in gut health, sharing practical information about why addressing the gut is often essential for resolving chronic illness.

Episode Highlights:

• Symptoms of specific types of bacterial overgrowth
• How a "negative" SIBO test might actually indicate the most challenging type to treat and what to look for instead
• The surprising connection between gut bacteria and seemingly unrelated conditions like rosacea, restless legs, and brain fog
• Tick-borne triggers and how they manifest in the gut
• Why treating SIBO with antibiotics alone often fails, and the fungal piece most doctors miss
• Simple physical signs (like fingernail ridges) that can reveal gut problems before expensive testing
• How anti-vinculin antibodies after food poisoning can paralyze the migrating motor complex, leading to chronic post-infectious IBS
• Why is combining rifaximin with bismuth is becoming the preferred protocol for hydrogen sulfide SIBO cases that don't respond to standard treatment
