Gluten intolerance symptoms should go away if you stop eating any more gluten. What can be mistaken for gluten intolerance? Many people will experience IBS-type symptoms such as bloating, wind, gurgling and abdominal pain after eating wheat and this can be due to the fermentable carbohydrate known as ‘fructans’ which are found in wheat, barley and rye. The immune system is not involved and instead the symptoms are caused by bacteria in the large intestine fermenting the poorly absorbed fructans. Patients who suffer with IBS or gut fermentation should be referred to a specialist dietitian who can guide them through the ‘Low FODMAP’ Diet which removes all

Other research suggests that wheat might affect the lining of some people’s digestive tracts. This lining usually keeps bacteria from leaking out of your intestines. But in people with a gluten intolerance, the lining may not work as it should, allowing bacteria into their blood or liver and causing inflammation. What are the symptoms of gluten intolerance? Video capsule endoscopy (VCE): VCE has a sensitivity of 89% and specificity of 95% for celiac diagnosis. This method of testing is more sensitive at detecting macroscopic atrophies in comparison with regular upper endoscopy (92% vs. 55%). VCE is also useful in detecting complications linked with celiac disease. People with celiac disease carry one or both of the HLA DQ2 and DQ8 genes, but so does up to 25-30% of the general population. Carrying HLA DQ2 and/or DQ8 is not a diagnosis of celiac disease nor does it mean you will ever develop celiac disease. However, if you carry HLA DQ2 and/or DQ8, your risk of developing celiac disease is 3% instead of the general population risk of 1%.
