Hi I m 18 and have recently found, well thought that I might be gluten intolerant and have been treating my diet as much, but over the past few days I have what feels like a constant pressure on my bowels, could it be that I am not gluten intolerant and may have IBS instead? I find that I also cannot eat too much sugar, or sugary drinks, no spicy food and nothing with caffeine. Please are you able to tell what this is?
