Is the gut the real engine of sepsis?

Host Nicole Kupchik is joined by Dr. Kaveh Hoda to unpack one of the most overlooked drivers of sepsis: the gut. Often called “the motor of MODS,” the GI tract can push the body toward recovery, or accelerate systemic collapse. In this episode, Dr. Hoda explains the importance of microbiome diversity, the breakdown of gut barriers leading to leaks and inflammation, and how critical illness disrupts the small intestine. More importantly, he shares what clinicians can do to support GI function at the bedside, from early nutrition strategies and listening to bowel sounds, to C.diff management. Plus, Sepsis Survivor Hailey Bain shares her story of septic shock, which was triggered by a ruptured appendix and originally mistaken for gynecologic pain. Her experience highlights how sepsis can escalate if early warning signs are missed.

The GI tract can ignite systemic inflammation, worsen organ failure, and shape overall prognosis. Critical illness rapidly destroys microbiome diversity. Within days in the ICU patients lose microbial variety, a major blow to immunity, mucosal integrity, and gut resilience. Even good bacteria can become harmful. Under stress and illness, bacteria that were once benign can act more virulent and contribute to sepsis progression. Antibiotics, proton pump inhibitors, and ICU stress can compound damage. While necessary interventions, they also accelerate microbiome disruption, making the gut even more vulnerable Clostridioides difficile, formerly known as clostridium difficile (C.diff) thrives when the microbiome collapses, however fecal microbiota transplant (FMT) has been changing the game. The transplant remains one of the most effective modern treatments for recurrent C.diff in critically ill patients. Sepsis survivors can struggle with long-term gut and nutrition problems. Muscle wasting, anorexia, IBS, malnutrition and increased infection risk require holistic post-ICU care and high protein nutrition. — Get in Touch: info@sepsis.org Or Visit Us At: SepsisPodcast.org Connect with Nicole on Socials: @nicolekupchik Connect with Sepsis Alliance on Socials: @sepsisalliance To Learn More About Sepsis, Visit Sepsis.org Produced by: Human Content and Sepsis Alliance Sepsis is a life-threatening emergency that happens when your body’s response to an infection damages vital organs and, often, causes death. In other words, it’s your body’s overactive and toxic response to an infection. Like strokes or heart attacks, sepsis is a medical emergency that requires rapid diagnosis and treatment. Sepsis can lead to severe sepsis and septic shock.
