What causes the stomach to grumble after food?

Although people often feel sleepy after a meal, eating makes the stomach, gallbladder, and pancreas begin important work. Stomach acids and bile salts from the gallbladder begin to break down food. Glucose from foods triggers insulin to be released from the pancreas. All the activity going on creates sounds, much like the various humming and ticking sounds when we first turn on a bunch of fans. Doctors and nurses actually listen for sounds from the stomach and intestines (collectively called bowel sounds) to assess whether the digestive tract is healthy and working. While there can be hypermotility sounds, usually a noisy gut is simply the normal digestive workings and should be of no concern. In patients with high gas, the lower bowel (more than the stomach) will give a wide range of sounds. Interestingly, the stomach and bowel make a variety of sounds, from low rumblings to high-pitched "tings" like someone hitting a glass with a spoon.
