SIBO and Gut Dysbiosis

Parasites such as Giardia are considered possible but less likely without relevant exposure. Fiber improvement does not prove SIBO because fiber can worsen SIBO in some people. Improvement with Metamucil is treated as a clue for gut ecology, bacterial overgrowth, or toxin binding rather than as a definitive test. SIBO is described as bacterial overgrowth in the small intestine that can fit gas and bloating symptoms. The article discusses breath testing, upper endoscopy sampling, and therapeutic trials as possible approaches to suspected SIBO. Rifaximin and botanical antimicrobials are presented as possible therapeutic-trial options for suspected SIBO.
