Stomach noises such as growling, rumbling and gurgling can occur while food is digesting both after and between meals, according to the Mayo Clinic. While hunger is often thought of as the cause of stomach growling, these noises are also produced by the release of acids and other digestive fluids in the stomach.
According to The Telegraph, stomach noises are amplified in the intestinal cavity when the intestines are empty. However, some stomach rumbling can be caused by the excessive consumption of carbonated beverages, as well as foods that are known to cause gas such as beans, cabbage, legumes, asparagus, Brussels sprouts and onions. Digestive problems and their associated stomach rumbling are also linked to a sedentary lifestyle. To minimize stomach noises, one should avoid eating quickly, be sure to chew foods thoroughly and drink plenty of fluids throughout the day. Staying physically active and reducing stress are also proven to help prevent digestive problems over the long term. While most stomach noise is completely normal, in some cases excessive stomach rumbling can signify a digestive disorder, such as irritable bowel syndrome, gastroesophageal reflux disease, lactose intolerance or stomach ulcers. In the case of any of these disorders, stomach rumbling is typically accompanied by gas, bloating, cramping and diarrhea.
