Re: I smell like feces why?!

You would have to go through your primary care doctor to get the test for it. Looks like it's a urine test. Cleaning up your diet would be a good idea regardless. Are you overweight? I've read that poor diet and/or obesity can cause changes in your Body Odor . Try eating healthy foods and exercising. Working up a sweat helps release toxins through your skin. See if that helps.
