Small Intestinal Bacterial Overgrowth (SIBO) Breath Test
Small intestinal bacterial overgrowth (SIBO) is a common cause of functional bloating, diarrhea, constipation and suspected malabsorption. SIBO is a condition in which colonic-type bacteria (resembling bacteria normally found in the colon) proliferate in large numbers in the small intestine.
Lactose Intolerance/Lactose Malabsorption Breath Test
Lactose intolerance is the inability to digest milk sugar lactose, causing gastrointestinal symptoms such as flatulence, bloating, cramps and diarrhea. This inability is the result of a deficiency of the lactase enzyme, which breaks down lactose into its simplest form.
Fructose Intolerance/Fructose Malabsorption Breath Test
Absorption of fructose is impaired by deficient fructose carriers in the small intestine’s enterocytes. This impairment results in an increased concentration of fructose in the entire intestine.
Sucrose Intolerance/Sucrose Malabsorption Breath Test
Sucrose intolerance, also called congenital sucrase-isomaltase deficiency (CSID) or sucrase-isomaltase deficiency, is the condition in which sucrase, an enzyme needed for proper metabolization of sucrose, is not produced in the small intestine.
