With more than 4000 square feet of surface area, our intestine is the most massive organ in the human body. The reason for the huge surface area is due to the primary digestive and absorptive function. Absorption directly into the bloodstream occurs through a specialized lining forming a tight barrier controlling which substances get absorbed and which are blocked. When the gut is inflamed by way of disease, toxins, or infection, defects in the integrity of the lining begin to appear which then allow the seepage into the bloodstream of undesirable particulate matter. This will trigger surface inflammation and a change in the flora of the gut, which in turn contribute to a plethora of undesirable symptoms. Similarly, small intestinal bacterial overgrowth (SIBO) occurs when bacteria from the colon begin to populate in the small intestine and interfere with the absorption of nutrients, causing symptoms like diarrhea and malnutrition. Dr. Gengo specializes in both the detection and treatment of leaky gut and SIBO.
