Depends on ur stomac: The gastric emptying scan / study: by eating a meal cooked w/ a tracer & following it; if it takes more than ~2 hrs, u have gastroparesis (more common in obese diabetics & requires meds to increase stomach motion). Make sure u follow instructions on (not) eating b4 the test so ur stomach is empty. The tracer is imaged & timed - it moves as fast as ur body allows. Obesity makes the images fuzzier.
