<unk>  <unk> , also termed<unk><unk> , or<unk>  bowel<unk><unk>  syndrome (SBBOS), is a disorder of excessive<unk>  growth in the<unk>  intestine. Unlike the colon (or large bowel), which is rich with<unk>  the<unk>  bowel usually has fewer than 100,000 organisms per millilitre. Patients with<unk><unk>  typically develop symptoms which may include nausea, bloating, vomiting, diarrhea, malnutrition, weight loss and malabsorption, which is caused by a number of mechanisms. The diagnosis of<unk><unk>  is made by a number of techniques, with the gold standard being an aspirate from the jejunum that grows in excess of 105<unk> per millilitre. Risk factors for the development of<unk><unk>  include dysmotility; anatomical disturbances in the bowel, including fistulae, diverticula and blind loops created after surgery, and resection of the ileo-cecal valve; gastroenteritis-induced alterations to the<unk>  intestine; and the use of certain medications, including proton pump inhibitors.<unk>  bowel<unk><unk>  syndrome is treated with an elemental diet or antibiotics, which may be given in a cyclic fashion to prevent tolerance to the antibiotics, sometimes followed by prokinetic drugs to prevent recurrence if dysmotility is a suspected cause.
