[|Human|] my son is 5 years old and his poop smells very bad this has happened maybe for the last 2 weeks and it comes in different colors depending on what he eats we have been giving him lots of blueberries and he is on a gluten free diet due to mild autism, should i be worried?
[|AI|]  Thanks for posting your query at Chat Doctor. The cause of foul smelling stools may be indigestion (malabsorption) or infection of the bowels. I am not sure that blueberries would provide him relief. If you are giving him gluten-free diet, please make sure that he has celiac disease. If celiac disease has already been diagnosed, the reason would be the malabsorption caused due to this disease where the epithelial lining of the intestinal cells is affected. These cells contain the enzymes required for the digestion. Since these cells are damaged, malabsorption occurs giving rise to foul smelling stools. I hope that helps. Feel free to revert in case of further queries.
