Treating SIBO and Its Comorbidities

The overgrowth of bacteria in the small intestine can be caused by many factors and is associated with several health issues. Small intestinal bacterial overgrowth (SIBO) can be detected with a simple hydrogen breath test, but which food plans work best for restoring balance in the gut microbiome?

Restoring normal flora populations may dramatically improve health and eradicate a range of symptoms.1,2 In a small study of obese children with SIBO, there was an increased risk for developing non-alcoholic fatty liver disease.3 The study concluded that the relationship between intestinal dysbiosis and diet can influence the gut-liver axis.3 In a study of adults undergoing gastric bypass surgery, SIBO was found in 15% of patients before surgery and up to 40% afterward in Roux-en-Y gastric bypass (RYGBP) patients. 4 It was also associated with lower weight loss.4

Small studies have found SIBO present in populations with pediatric obesity,5 papulopustular rosacea,6 spinal cord injury with deep vein thrombosis,7 active H. pylori infection,9 and chronic pancreatitis.9 In an interesting contrast, researchers who found a lower prevalence of SIBO in type 1 diabetes patients suggest this may be due to nutritional interventions in the management of the disease.10

Nutritional interventions that reduce the fermentation of carbohydrates in the gut can help restore a healthy balance among gut bacteria. Because of the diverse comorbid conditions associated with it and response to therapy, properly addressing SIBO may require individualizing interventions and tailoring treatment to address lifestyle factors and nutritional needs.

In this video, IFM educator Thomas Sult, MD, discusses nutritional interventions for depriving bacteria that cause SIBO of fermentable foods:

In addition to the latest research, you’ll also learn about how to develop individualized treatment protocols using lifestyle, diet, nutraceuticals, pharmaceuticals, and botanicals to help restore gut health.

Understanding the Mind-Body Connection Can Help GI Patients

Given the strong mind-body/brain-gut connection, it is clear that when the normal integrity of the GI tract is compromised, distant systemic complaints can result, even in the absence of overt GI symptoms. Integrative approaches may be helpful for reducing symptoms and reestablishing a healthy gut and a healthy mind.

The Gut-Brain Axis & Systems Biology

The gut-brain axis is the bidirectional communication between the gut and the brain, which occurs through multiple pathways that include hormonal, neural, and immune mediators. Interestingly, the signals along this axis can originate in the gut, the brain, or both, with the objective of maintaining normal gut function and appropriate behavior.
