What causes the stomach to grumble?

Answer 1

Eat something. Many times when you are hungry, your stomach will "growl" or "grumble." This is very normal. Your stomach is a muscular organ that is part of the digestive system. The stomach's role is to break down food with digestive acids and juices through repetitive contractions. When you have not eaten for several hours and are hungry, your stomach will still contract in attempts to digest food that is not present. Therefore, the walls of the stomach are rubbing against each other which sometimes makes an audible noise like a "grumbling." When the stomach is empty, air is more likely to be present. Air bubbles in the stomach can then cause a "gurgling" noise as well. So, the noises your stomach is making are normal. This is one of your body's mechanisms for letting you know that it is time to eat and that more nutrients are required. Hunger...eat!! Keep a log of the certain foods you eat. Some foods can cause indigestion, gas and thus rumbling of the stomach or release of gas by passing wind either by burp or out the shoot scoop. This can be embarrassing for some people. Some gassy foods are broccoli, brussel sprouts, hot sauces, garlic sausage, etc., alcohol (especially beer ... awwww). You can buy pills over-the-counter called Beano and that will help with the gas. It also means you probably aren't drinking enough water. You should be drinking 8 - 8 ounce glasses of water per day and more if you are in a hot country or exercising and perspiring more. If you just eat and sit around you most certainly will have rumblings and a build-up of gas.

Answer 2

The stomach grumbles when the stomach walls contract and the acids and juices splash around which creates the grumbling sound.
