hi we are what we eat by the sound of it you are in need of fibre. you need to get healthy keep of fast foods and junk foods and forget sodas just be doing that will help a lot. and that would be a good start along with exercise. good luck
for the last month or so my stools have been looser than normal no real form. i am 30 and don't live healthy right now. it's been going on for the last month or more that stools are no longer "normal" they aren't shaped and often very loose (not watery). i don't eat healthy or work out normally. . like many i googled and the first result would be colon cancer- so i figured i would be better off asking an expert instead.
