"You want to hear what the stool, the poop, sounds like when it hits the water. If it sounds like a bombardier, you know, 'plop, plop, plop,' that's not right because it means you're constipated. It means the food is too hard by the time it comes out. It should hit the water like a diver from Acapulco hits the water [swoosh]."
The next thing Dr. Oz recommends is looking at your stool—c'mon, you've done it before! You should look twice—look at the shape and then, the color.
"It should be an S shape and you want to make sure the color's normal because the color of the poop tells you a lot about how you made it," Dr. Oz says. "You don't want [pieces]. Food is a medicine for you. It helps you. [If the stool is in pieces] by the time you finished digesting your food, you don't have enough of it left to poop out in the right way and probably it's hurt the colon that has to process it. At the end of the day you can analyze your body really effectively by looking at what comes out of your body."
