a mobility test to determine whether someone has any structural problems in the small intestine.blood tests to detect markers of autoimmunity or inflammation.The existing tests for SIBO are not always precise, so a doctor may recommend other tests to get a better picture of someone’s digestive health. This makes diagnosis more difficult for those who have less conclusive test results. It is worth noting that with small bowel aspirate testing, as well as breath testing, there is no universally accepted threshold for what constitutes a positive SIBO result.
They then send the sample to a laboratory, which analyzes the bacteria present. When the device reaches the duodenum, which is where the stomach joins up with the small intestine, doctors use the endoscope to take a tissue sample. Small bowel aspirate tests involve a doctor performing an endoscopy, which means inserting a small, thin camera through the mouth and down into the stomach. This is the gold standard for SIBO testing, but it is a more invasive test. However, others argue that this rapid absorption can be an advantage, as it makes it less likely that the sugar will reach the colon, where it would generate a false positive result by feeding a large number of bacteria there. Some scientists have criticized this method, as the body can absorb glucose quickly, which means that it might not reach the area of overgrowth. Some doctors perform glucose breath testing instead of lactulose breath testing. A breath test measures these gases as a person exhales. When bacteria break the sugar down, they produce gases, which enter the bloodstream and travel to the lungs. They then drink a sugary solution containing lactulose, which is a sugar that only gut bacteria can break down. They also show whether the overgrowth consists mainly of hydrogen- or methane-producing microbes.Ī person has to fast for 24 hours before the test. The results of this test can confirm a SIBO diagnosis and reveal the extent of the overgrowth. Breath testingĪ lactulose breath test measures the concentration of hydrogen and methane in a person’s breath. If they suspect SIBO, they will recommend testing. They may feel the abdomen for signs of excess gas or bloating. Alcohol abuse: Excessive alcohol consumption can damage the microbiome, leading to dysbiosis, damage to the intestinal walls, and inflammation.Ī doctor will diagnose SIBO by asking about a person’s symptoms and medical history.According to a 2018 study, people who have undergone a colectomy are more at risk of developing SIBO. Examples include small bowel diverticulosis, fistulas, and a shortened colon. Structural differences: Sometimes, SIBO occurs because a person has structural differences in the digestive tract.However, there is a lack of conclusive evidence on this, and low motility may be a more important risk factor. Researchers believe that people who take proton pump inhibitors (PPIs), have autoimmune gastritis, or have undergone a gastrectomy have an increased risk of hypochlorhydria and SIBO. When someone does not have sufficient stomach acid, it may be possible for bacteria to migrate further up the digestive tract than usual, as the environment is not acidic enough to kill them. Hypochlorhydria: This term describes low levels of stomach acid.Research into how different species of microorganisms influence digestion is still ongoing, but previous studies suggest that people with IBS often have less diversity, fewer beneficial species, and higher amounts of methane-producing species in their microbiome, which can slow motility.
