How do you know if you have stomach distension or too much stool in there?

X-ray /motility test: Most people in america will stool anywhere from 3x/day to 1x/ every 3-4 days. Abdominal x-rays (obstruction series) will address volume of gas, liquid, solids in your gut & suggest possible pathology (full or partial blockage, ileus, megacolon, etc.). A sitz marker test (colon transit study) calculates the time a test pill moves through your GI system--suggesting colon &/or rectal problems to fix.
