Instead, small intestine bacterial overgrowth should be considered in the presence of a compilation of many non-specific symptoms each by itself would not be worrisome but together can point to the potential diagnosis. There are no specific complaints or physical findings that can make the diagnosis of SIBO. SLIDESHOW IBS - Irritable Bowel Syndrome: Symptoms, Diet, Treatment See Slideshow Scleroderma, leukemia, and lymphoma may also increase the risk of developing small intestine bacterial overgrowth.Achlorhydria (chronic inflammation causes the stomach to become unable to produce acid).Other intestinal diseases that may be associated with SIBO include: People with diabetes with autonomic dysfunction (nerve damage) may also develop dysmotility. a rare condition called intestinal pseudo-obstruction.diverticuli or outpouchings of the small intestine, andīowel motility may be affected by neurologic diseases including:.bowel strictures and adhesions that can lead to intermittent bowel obstructions,.complications from gastric bypass surgery,.Finally, the ileocecal valve prevents stool from refluxing from the colon (large intestine) into the ileum or the last part of the small intestine.Īny illness or disease that affects the body's defense mechanism puts a person at risk for SIBO, but the majority of people develop SIBO because of an intestinal motility problem. Bacterial growth is hindered by the presence of bile and immunoglobulins. The body has many protective mechanisms to keep bacteria under control, including stomach acidity and intestinal motility, the ability of the intestine to move its contents downstream at an appropriate speed. Small intestine bowel overgrowth is often associated with another illness that affects the function of the small intestine.
This article will discuss only the type of SIBO associated with intestinal diseases and conditions.Īssociated SIBO: Types of other diseases or conditions associated with it The colon is not as clean as the small intestine and reflux, or backflow, of stool into the small intestine can colonize it with colonic bacteria. This may be the result of a lack of adequate stomach acid, damage to the intestine by toxins like alcohol, or a decrease in the speed at which the small intestine transfers material to the colon. However, if the normal function of the intestine is compromised, bacterial overgrowth may occur. The normal bacteria (flora) of the gut, perform important functions, helping to digest certain vitamins like folic acid and vitamin K, and they protect the intestine from being invaded by disease-causing bacteria. The refuse is dumped into the large intestine, or colon, where water is absorbed and the feces become more solid and are eliminated from the body. The stomach receives food, mixes it with acid and digestive juices, and turns it into a clean slurry that is pushed through the three parts of the small intestine (duodenum, jejunum, ileum) where the nutrients are absorbed into the body. The small intestine is a relatively clean place. The prognosis depends upon how well the associated illnesses are managed and the response to therapy.Any underlying illness will also need to be addressed at the same time once therapy is started for SIBO.Antibiotics may be prescribed but the type and length of treatment depend upon the patient and the symptoms.Blood tests, breathing tests, and biopsies or tissue samples from the small intestine may be required to diagnose either type of SIBO.The diagnosis is often one of exclusion, making sure that other causes of the symptoms are not present.This article deals only with SIBO associated with intestinal diseases and conditions. The type associated with intestinal diseases and conditions may result in, the inability of the body to absorb nutrients from the intestine and may lead to malnutrition and vitamin deficiencies that may help direct testing to find the diagnosis.SIBO of either type can give rise to similar symptoms including indigestion, diarrhea, bloating, abdominal pain, and diarrhea or loose stools.One is associated with identifiable diseases or conditions of the intestines. SIBO can be considered to be of two types.SIBO stands for small intestinal bacterial overgrowth.Picture of SIBO (Small Intestinal Bacterial Overgrowth)
