although the exact cause of celiac disease is not known having certain genes increases your risk. you are more likely to have these genes and may get celiac disease if you have a first-degree relative (mother father brother sister son or daughter) with the condition. environmental factors such as viral or bacterial infections may trigger changes in the small intestine of a person with these genes. then eating foods that contain gluten can trigger an abnormal immune system response. eventually digestion and absorption problems may result. research continues on how genetic environmental and immune factors interact and affect a person's symptoms at what age they begin and whether long-term health problems develop. webmd medical reference from healthwise this information is not intended to replace the advice of a doctor. healthwise disclaims any liability for the decisions you make based on this information. © 1995-2011 healthwise incorporated. healthwise healthwise for every health decision and the healthwise logo are trademarks of healthwise incorporated.
