SMALL ITESTINAL BACTERIAL OVERGROWTH (SIBO)

SIBO Made Simple | EP 06 | Prebiotic and Probiotic Protocols: a SIBO Management Misnomer with Dr. Jason Hawrelak

The article from Feed Me Phoebe features an interview with Dr. Jason Hawrelak, a researcher and clinician specializing in gut health, discussing the roles of prebiotics and probiotics in treating Small Intestinal Bacterial Overgrowth (SIBO) and Irritable Bowel Syndrome (IBS). Dr. Hawrelak explains that certain prebiotic fibers can aid in improving gut motility and reducing the risk of SIBO relapse, while specific probiotics may help alleviate IBS symptoms. He also addresses common misconceptions about the low FODMAP diet, emphasizing its potential to disrupt the gut microbiome if followed long-term. The discussion provides insights into how dietary choices and supplements can support gut health and manage SIBO and IBS symptoms.

The First Advanced Network Analysis of the Small Bowel Microbiome in Small Intestinal Bacterial Overgrowth (SIBO)

This study analysed the small bowel microbiome in people with Small Intestinal Bacterial Overgrowth (SIBO) using advanced network methods. It found that SIBO causes significant disruption to the normal balance and connections between gut bacteria, mainly due to higher levels of Escherichia and Klebsiella bacteria. These changes reduce the overall health and stability of the microbial community.

Root causes of SIBO: Motality Issues

The article explains that SIBO (small intestinal bacterial overgrowth) often results not from bacteria themselves but from slowed gut motility, which creates the perfect environment for bacterial overgrowth. Key factors disrupting motility include chronic inflammation triggered by endotoxins, abolition of the migrating motor complex (MMC), methane gas production that directly slows intestinal movement, and long‑term stress or vagus nerve dysfunction disrupting the gut’s rest‑digest rhythm.

Personality, Anxiety, and Stress in Patients with Small Intestine Bacterial Overgrowth Syndrome. The Polish Preliminary Study

The article explores the psychological factors associated with Small Intestine Bacterial Overgrowth (SIBO). It reveals that individuals with SIBO often exhibit higher levels of anxiety and stress, along with certain personality traits, compared to the general population. The study suggests that these psychological factors may influence the severity and progression of SIBO, highlighting the importance of considering mental health in the management of this condition.

The Stress & SIBO Connection

The article by Dr. Amy Myers discusses how chronic stress can contribute to Small Intestinal Bacterial Overgrowth (SIBO), a condition where excessive bacteria inhabit the small intestine. Stress impairs digestive functions by reducing stomach acid production and disrupting the migrating motor complex, which is responsible for clearing bacteria from the small intestine. Additionally, stress weakens the gut's mucosal immunity, making it more susceptible to infections.

Biofilms & Why You Need A Biofilm Disruptor

The article by Dr. Amy Myers explains that biofilms are clusters of microorganisms—such as bacteria, fungi, and parasites—encased in a protective slime layer. These biofilms can form in various parts of the body, including the gut, and are notoriously difficult to eliminate. In the digestive system, biofilms can disrupt digestion, weaken immunity, and contribute to conditions like Candida overgrowth. To address this, Dr. Myers recommends biofilm disruptors—supplements designed to break down these protective layers.

SIBO: Small Intestinal Bacteria Overgrowth - Root Cause

To prevent relapse of Small Intestinal Bacterial Overgrowth (SIBO), it's essential to address underlying causes and support gut health. Key strategies include stimulating the migrating motor complex (MMC) with prokinetic agents, following a SIBO-specific diet, and supporting stomach acid production if deficient. Additionally, removing proton pump inhibitors and antacids, undergoing visceral manipulation to improve motility, and correcting anatomical issues like ileocecal valve dysfunction can be beneficial. Managing stress and treating concurrent conditions that contribute to SIBO are also important. Implementing these measures can help maintain remission and prevent recurrence of SIBO symptoms.

Small Intestinal Bacterial Overgrowth: Comprehensive Review of Diagnosis, Prevention, and Treatment Methods

This review explores Small Intestinal Bacterial Overgrowth (SIBO), a common gastrointestinal disorder where excessive bacteria accumulate in the small intestine, leading to symptoms such as bloating, gas, abdominal pain, and malabsorption of nutrients like vitamin B12 and folate. Diagnosis is often delayed because testing can be invasive. The paper reviews current diagnostic approaches, including breath tests, and discusses prevention and treatment strategies—such as antibiotics and dietary changes—to restore healthy gut microbial balance and improve symptoms among affected individuals.
