Sugar Intolerance and IBS

in Sugar

Latest research finds have pointed out at a high relationship between sugar found in lactose, sorbitol and fructose, and IBS. If you are suffering from IBS condition, these findings will help you to know whether sugar intolerance is causing the symptoms in your system. Here are the details of the research.

Sugar Intolerance Combinations

This intolerance is also linked with functional bowel disease, by a small research study which involved HBT given to 25 patients, who had consumed a combination of solutions, including lactose, sorbitol, fructose, sucrose, and a blend of fructose and sorbitol. A high 90% showed sugar intolerance to at least one of the above sugars. When the consumption of this particular substance was restricted 40% of them found marked improvement.

Another research study recorded results from studying 239 patients with functional bowel disorders, found 94 had diagnostic criteria for IBS, while others had functional complaints. When they were subjected to hydrogen and methane tests, 90% of them were found to have intolerance, while maximum number were showing sugar intolerance to more than one sugar. Diet restrictions resulted symptom improvement in more than 50% of the patients.

Small Intestine Bacterial Overgrowth

Another group maintains that small intestine bacterial overgrowth (SIBO) is of importance in IBS symptomatology, suggesting that SIBO can be diagnosed through use of hydrogen breath testing (HBT), after lactulose, which cannot be digested by the body, is ingested. It was construed that bacteria present in the small intestine brings fermentation, which shows up in the rising hydrogen breath levels, after an individual drinks lactulose solution. The underlying problem was SIBO and not lactose intolerance, as per a larger study on 98 IBS sufferers for SIBO and sugar intolerance who discovered that those tested positive for lactose intolerance, also tested positive on lactulose breath testing. These IBS patients were appreciably more likely to have positive HBTs after lactose, fructose and sorbitol are ingested, than those without SIBO. SIBO patients were later administered antibiotics to avoid a positive response to lactulose test. The conclusions point out at SIBO as the reason for positive intolerance testing, while in reality they may not have intolerance to sugar.

Though there have been different opinions about the basic problem, these studies have clearly established a relationship between intolerance to sugar and IBS. Therefore an IBS sufferer can evaluate the role of lactose, fructose, and sorbitol intolerance apart from SIBO in taking notice how it effects them when they have ingested anything that contains the above sugars. Therefore consult your doctor to know whether he recommends a sugar intolerance test. Also, try to maintain a food diary, and eliminate foods to find out whether by limiting sugars in your diet your condition gets better.
