Once in a while like once in a week I get oily stool. First stool would be normal and after that a oily stool comes. Its literally oily liquid with some foam sometimes and enough quantity. I am unable to pinpoint that which food item is causing that. Sometimes even after eating normal food i am having this problem. So i am worried what it could be. Is it something serious disease. My age is only 22. Please help. No pain nothing but when i am getting this type of stool my stomach starts making noises in advance before going to toilet and i can feel that.
