Small intestine bacterial overgrowth1/1/2024 ![]() The advantage to this test is that it can diagnose overgrowth in the distal end of the Small Intestine, thought to be more common. If there is an overgrowth, this will be reflected in the levels of Hydrogen and/or Methane. After they consume lactulose, they make gas. Only bacteria have the proper enzymes to do this. ![]() There are two (2) types of tests may be used: Lactulose or Glucose. The diet removes much of the food that would feed the bacteria, allowing for a clear reaction to the sugar drink. Patients drink a sugar solution of glucose or lactulose after a 1 or 2 day preparatory diet. The gas is graphed over the SI transit time of 2 or 3 hours & compared to baseline. Hydrogen & Methane are gases produced by bacteria, not by humans. Breath testing measures the hydrogen & methane gas produced by bacteria in the Small Intestine that has diffused into the blood, then lungs, for expiration. Luckily, there is a non-invasive test which is commonly used in SIBO research the Hydrogen Breath Test.Ī hydrogen breath test can be used to diagnose several conditions: H pylori infection, carbohydrate malabsorption (ex. And stool testing predominantly reflects the large intestine (LI). The middle portion, which is substantial (about 17 feet) is not accessible, other than by surgery. If we want to see or sample the SI, endoscopy only reaches into the top portion, and colonoscopy only reaches into the end portion. The small intestine (SI) is a hard place to get to. An interesting study was performed on asymptomatic morbidly obese subjects and SIBO was found in 17% as compared to 2.5% in non-obese persons In a small group of elderly people (70 to 94 years old) with lactose malabsorption, SIBO was documented in 90%. In liver cirrhosis, SIBO was diagnosed in more than 50% of cases. The prevalence of SIBO in coeliac disease non-responding to a gluten-free diet was up to 50%. ![]() According to different studies with the investigation of small sets of clinically healthy people as a control, findings consistent with SIBO were found in 2.5% to 22%.įor instance, the prevalence of SIBO in patients fulfilling diagnostic criteria for irritable bowel syndrome was 30%-85%. Of course, diagnostic yield also depends on the methods used for investigation. SIBO might be asymptomatic or with non-specific symptoms only, and last but not least, all symptoms might be incorrectly ascribed to the underlying disease (leading to SIBO). Some patients may not seek healthcare or SIBO may not be properly diagnosed by medical investigations. In general, SIBO is substantially underdiagnosed. Finally, the bacteria excrete acids which in high amounts can cause neurological and cognitive symptoms.Immune system reaction to bacteria and their cell walls causes chronic fatigue and body pain and burdens the liver. Bacteria themselves can also enter the body/bloodstream.This causes food allergies/ sensitivities. Through the damaged lining, larger food particles not able to be fully digested, enter into the body which the immune system reacts to.They can cause fat absorption leading to deficiencies of vitamins A & D and fatty stools.Excess gas can also cause belching and flatulence. The gas causes abdominal bloating, abdominal pain, constipation, diarrhea or both (the symptoms of IBS). After eating our food, they produce excess gas within our Small intestine.They consume food unable to be absorbed due to lining damage of the small intestine, which creates more bacterial overgrowth.They consume some of our food which over time leads to deficiencies in their favorite nutrients such as iron and B12, causing anemia.The bacteria interfere with our normal digestion and absorption of food and are associated with damage to the lining or membrane of the Small Intestine. The infection is of bacteria that normally live in the gastrointestinal tract but have abnormally overgrown in a location not meant for so many bacteria. Small Intestine Bacterial Overgrowth (SIBO) is a chronic bacterial infection of the small intestine.
