Gut rumbling
That odd, gurgling sound you hear after dinner is air and fluid moving through the digestive tract. If you hear grumbling on an empty stomach, your gut may be cleaning out leftover bits of food and fluid. Or, of course, it could be time to eat: When you’re hungry, the brain sends a signal to the intestines that stimulate the same action. If you experience high-pitched noises with cramping, pain, or nausea, but no bowel movements, get it checked out-it could be partial bowel obstruction, which sometimes requires surgery.
