What is Small Intestinal Bacterial Overgrowth or SIBO?
This is a medical condition where the lowly gut contains an abnormally large amount or phone number of bacteria and also the types of bacterium present in the small intestine resemble those bacterium present in the colon . humble intestine , which is the small bowel , is a part of the digestive system which tie the belly with the colon or the heavy bowel . The function of the small bowel is digestion and absorption of food in the organic structure . There are three parts of the small bowel , namely : the duodenum , the jejunum and the ileum .
Normally bacteria are present in the gastrointestinal tract , including the small gut . Colon incorporate the highest number of bacterium , and the small intestine has less amount of bacteria . The types of bacteria present in the Aspinwall are unlike from the bacteria present in the little intestine . Small enteral bacterial overgrowth or SIBO is also refer to as lowly intestine bacterial overgrowth syndrome ( SBBOS ) .
Pathophysiology of Small Intestinal Bacterial Overgrowth or SIBO
When the food gets digested in the intestine , by the bacteria in the bowel , they raise gas . Accumulation of this gas in the abdomen run to abdominal bloating or distension resulting in abdominal pain . The increased amount of gas also produces spare flatulence or wind . The bacteria are cerebrate to commute the nutrient into gist , which irritate or harm the cells that describe the small intestine and El Salvadoran colon . These harmful / irritating message conduct to looseness of the bowels . In some cases , bacteria can also bring forth methane gas which may cause constipation . If the bacteria that are present in the small-scale gut increment to large number , then it starts to compete for the nutrient with the human body resulting in malnutrition and mineral and vitamin deficiencies . In severe stages of low intestinal bacterial giantism or SIBO , the bacteria use up a good deal of nutrient consumed , so much that there are not enough nutritionist’s calorie for the body to thrive which ensue in system of weights going of the affected role .
The Relationship between the Small Intestine and Bacteria
Before the baby is born , there are no bacteria present in the gastrointestinal tract . However , during the birth , the bacterium present in female parent ’s colon and vagina get swallowed by the baby and multiply in the baby ’s GI pathway in the subsequent few workweek or months . The relationship between the human body and normal intestinal bacterium is unmanageable to explicate . Both benefit each other . The bacterium profit from the moist , strong , surround present in the small gut and the continuous menstruation of nutrient down the GI tract is pure for thriving of the bacteria . The human physical structure benefits from normal bacteria in the next ways :
The resistant organization of the GI nerve tract including the small intestine helps in protect the intestine from disease - get bacterium , virus and parasites . The intestine tends to attack only the harmful bacteria and becomes tolerant of the normal bacterium . The intestine also protect itself from both harmful as well as normal bacteria through the chase :
Relationship between Small Intestinal Bacterial Overgrowths or SIBO & Irritable Bowel Syndrome (IBS)
One of the coarse gastrointestinal problems includesirritable intestine syndrome ( IBS ) . Irritable intestine syndrome is a chronic condition and the distinctive symptoms of IBS comprise of hurting in the stomach , bloat , alterations in patient role ’s bowel riding habit , such asdiarrheaor irregularity with flatulency . Symptoms of IBS can be continuous or can vacillate over a menses of months , geezerhood or even decades .
There are no conclusive symptomatic tests for IBS and the diagnosis is made on the basis of patient ’s history , symptoms and tests which govern out other disease which have similar symptoms , such asinfections , ulcers , Cancer , tissue paper inflaming and intestinal impediment .
The symptom of irritable gut syndrome are remarkably standardized to the symptom of pocket-sized intestinal bacterial giantism or SIBO . It is thought that little intestinal bacterial overgrowth or SIBO may also be causing the symptoms in some patients who have IBS . This theory is further tone up from the fact that many patients suffering from IBS also have an unnatural atomic number 1 breath test . Other than this , IBS patients also chance improvement in their symptom after accept antibiotic , which is the first line of handling for little intestinal bacterial gigantism or SIBO . However , enquiry is still being conduct out regarding this hypothesis .
Causes of Small Intestinal Bacterial Overgrowth or SIBO
The GI tract is a muscular underground in which the intellectual nourishment which is to be stick out travels along before reach the Costa Rican colon . In normal conditions , the coordinate action of the tum and small bowel musculus helps in propelling the food from the stomach , via the small intestine and into the colon . This coordinated hefty action also move the bacteria from the small intestine along with restrict the number of bacterium present in the small bowel . However , if a disorder or any type or a trouble occurs , then it interferes or hinder the normal activity of the small intestine resulting in collection of bacteria and increase in the identification number of bacteria by its staying longer and multiplying in the small intestine which results in Small enteric bacterial overgrowth or SIBO . The absence or decrease of the normal hefty activeness of the small intestine can also allow the bacteria to move rearwards into the small intestine , from the El Salvadoran colon .
There are many conditions which are associate with little intestinal bacterial overgrowth or SIBO and some of the vulgar I are listed below :
Signs & Symptoms of Small Intestinal Bacteria Overgrowth or SIBO
Diagnosis of Small Intestinal Bacterial Overgrowth or SIBO
Bacterial refinement from the minuscule intestine : culture of bacteria is one of the method acting for diagnose the condition of Small Intestinal Bacterial Overgrowth ( SIBO ) . A sample of fluid which hold back bacterium is taken from the small intestine and culture is done on it to determine the exact number of bacteria present in the sample . In this procedure , a long flexible tube is passed through the nose of the patient , into the throat and down the esophagus via the abdomen to assemble the fluid from the pocket-sized gut .
Problems which can be present in this method ( culturing ) for diagnose SIBO are :
Hydrogen Breath Test ( HBT):The bacteria which exist in the colon can digest by using saccharide and sugars as their food . Gas is produced when the normal bacterium present in the colon digests carbohydrate and sugars . This gas is usually carbon dioxide , along with methane and hydrogen in smaller quantities . Small quantities of these gases get absorb through the Costa Rican colon lining into the line of descent where they pass on and travel to the lung and get eliminate through a person ’s breath . limited analyzer are used to measure these gases in the breath .
Procedure of the Hydrogen Breath Test : affected role needs to fast for a lower limit of 12 hour before the atomic number 1 breath test . The patient role is then tell to inflate a small balloon using a single breath of air travel . A little amount of the test sugar ( glucose or lactulose ) is then ingested into it . The sampling of the breath are then analyzed for methane and hydrogen every 15 arcminute for three hours or more .
Treatment of Small Intestinal Bacterial Overgrowth or SIBO
small-scale Intestinal Bacterial Overgrowth or SIBO has been hump for several years as a trouble which occurs as a result of enteral blockage and disorders of intestinal muscles . antibiotic are the first line of treatment and they are quite effective . The implicit in cause of SIBO is not well-defined and patient has return of symptoms after the antibiotic drug are barricade .
Small Intestinal Bacterial Overgrowth or SIBO & Irritable Bowel Syndrome (IBS)
Scientific studies are carried out regarding the intervention of IBS with the treatment modality that presumes the possibility of underlying Small Intestinal Bacterial Overgrowth or SIBO . unwritten antibiotics and probiotic microflora are the two most common treatments for Small Intestinal Bacterial Overgrowth or SIBO in patients who also suffer from testy intestine syndrome . Probiotics are nothing , but unrecorded bacteria which when ingested produce a beneficial effect in the patient . There are many antibiotics , which can be used one by one or in compounding for treatment and which have been successful . Standard dosages of antibiotic are used for one to two weeks . probiotic can be used in combination with antibiotic drug or may be used alone for keep up maintenance .
Antibiotics vs. Probiotics for Treating Small Intestinal Bacterial Overgrowth or SIBO
According to some expert , light - term ( 7 to 14 days ) treatment with antibiotic drug is more efficient for Small Intestinal Bacterial Overgrowth or SIBO than probiotic flora . However , there are some disadvantages of using antibiotics ; specifically the one where there are chances of recurrence of symptom of Small Intestinal Bacterial Overgrowth or SIBO after discontinuance of treatment . In such affected role , repeated or prolonged form of antibiotics may be needed . There is , however , a concern for prescribing sustain or repeated courses of antibiotics because of their long - full term side essence .
There is less business organization or risk regarding long - terminus side effect with probiotics ; and for this reason doctors are more willing to prescribe probiotics to care for Small Intestinal Bacterial Overgrowth or SIBO for extend menstruation of metre or repeatedly . Another choice is to set out the treatment initially with a inadequate course of antibiotics and follow it with long - term probiotics . Research is still go on regarding comparing of probiotics , antibiotics and combination of probiotic microflora and antibiotics .
