Small Intestinal Bacterial Overgrowth

چکیده
Small intestinal bacterial overgrowth (SIBO) is characterized by an overgrowth of various types of bacteria in the small intestine, bacteria which are largely only found in the colon. SIBO was initially thought of as a rare condition; however, it is now recognized as a more prevalent digestive disorder than previously acknowledged. A meta-analysis has shown the prevalence of SIBO to be approximately 64% among patients with irritable bowel syndrome (IBS).[1] The symptoms of SIBO vary, from mild (constipation, gas, bloating) to suffering from chronic diarrhea, weight loss, and malabsorption. It has been realized that the symptoms of SIBO closely overlap symptoms of IBS, which allows for most patients to be wrongly diagnosed with IBS.

متن کاملAbnormal breath tests to lactose, fructose and sorbitol in irritable bowel syndrome may be explained by small intestinal bacterial overgrowth.
BACKGROUND Small intestinal bacterial overgrowth and sugar malabsorption (lactose, fructose, sorbitol) may play a role in irritable bowel syndrome. The lactulose breath test is a reliable and non-invasive test for the diagnosis of small intestinal bacterial overgrowth. The lactose, fructose and sorbitol hydrogen breath tests are widely used to detect specific sugar malabsorption. AIM To asses...

متن کاملThe role of small intestinal bacterial overgrowth, intestinal permeability, endotoxaemia, and tumour necrosis factor á in the pathogenesis of non-alcoholic steatohepatitis
Background—Small intestinal bacterial overgrowth may contribute to the development of non-alcoholic steatohepatitis, perhaps by increasing intestinal permeability and promoting the absorption of endotoxin or other enteric bacterial products. Aims—To investigate the prevalence of small intestinal bacterial overgrowth, increased intestinal permeability, elevated endotoxin, and tumour necrosis fac...
