A stomach rumble is a rumbling, growling or gurgling noise that occurs from the movements of fluid and gas in the intestines (in the vicinity of but not actually within the stomach). This process occurs in some animals, including humans. The sound occurs when gases in the body flow through the small intestine. As waves of muscle contractions move foods and gases through the digestive system, the food is pushed against the intestinal wall, which induces the noise. The process of these contractions is also known as peristalsis, which is the ultimate cause of the rumble.
The scientific name for a rumbling stomach, Borborygmus (pronounced //; plural borborygmi) is related to the 16th-century French word borborygme, itself from Latin, ultimately from Ancient Greek βορβορυγμός (borborygmós). The Greeks onomatopoetically coined the word.
Other causes 
Other causes of stomach rumbles:
- Incomplete digestion of food can lead to excess gas in the intestine. In humans, this can be due to incomplete digestion of carbohydrate-containing foods, including milk and other dairy products (lactose intolerance or the use of α-glucosidase inhibitors by diabetics), gluten (protein in wheat, barley, and rye) (celiac disease), fruits, vegetables, beans, legumes, and high-fiber whole grains. In rare instances, excessive abdominal noise may be a sign of digestive disease, especially when accompanied by abdominal bloating, abdominal pain, diarrhea or constipation. Some examples of diseases that may be associated with this symptom include carcinoid neoplasm and celiac sprue.
- Louder rumbles may occur when one is hungry. Around two hours after the stomach has been emptied, it sends signals to the brain, which tells the digestive muscles to restart peristalsis in a wave called the migrating motor complex. Food left behind after the first cycle is swept up, and the vibrations of the empty stomach cause hunger. Appetite plays a big role in this situation. Peristalsis recurs about every hour, and one's appetite may cause 10- to 20-minute food cravings.
- Stomach rumbles can form further along the gastrointestinal system when air is swallowed while talking, eating, and drinking. This phenomenon occurs in most people and is typical.
- Consuming high-fiber foods such as cabbage or beans can produce more gas because they are harder for the digestive system to break down.
Diseases and conditions 
||This section contains instructions, advice, or how-to content. (March 2012)|
- Celiac disease is a condition that prevents the small intestine from absorbing parts of food that are needed to stay healthy. The cause is unknown. Consuming foods containing gluten is dangerous for people with this disease. Intestinal villi help to absorb nutrients from food, but when gluten is consumed, the immune system attacks these villi as a result. Symptoms may include abdominal pain, nausea, and bulky or foul smelling stools.
- Colitis is swelling of the large intestine. The many different forms of colitis include cytomegalovirus or Cryptosporidium infection, and necrotizing and pseudomembranous colitis. The usual causes of colitis are infection and lack of blood flow. Symptoms may include bloody stools, chills, dehydration, diarrhea, and fever.
- Diverticulitis is a condition where small bulging sacs, usually found in the large intestine, become inflamed or infected. The most probable cause is a low-fiber diet, possibly a result of eating processed food. Diverticulitis is usually seen in about half the American population over the age of 60. Symptoms may include bloating, fever, and nausea.
- Irritable bowel syndrome, a disorder in the lower intestinal tract, is usually accompanied by other symptoms, such as abdominal pain and diarrhea. It is more common in women and it usually occurs during early adulthood. There are many risk factors such as emotional stress and a low-fiber diet. The best way to treat this disorder is by changing diet and exercising.
|Celiac disease||Lifelong gluten-free diet, avoid anything containing wheat, barley, rye, and possibly oats|
|Colitis||Depends on the cause of the disease: If caused by inflammation, colitis is treated with medicines such as ganciclovir and valganciclovir. If caused by infection, it is treated with nitazoxanide (antiprotozoal agent). If caused by lack of blood flow, it is treated with a liquid diet and antibiotics.|
|Diverticulitis||Depends on how severe symptoms are:
If symptoms are minimal, treat by:
If symptoms are somewhat severe, doctors would provide antibiotics. Avoid foods such as beans and peas along with coarse grains and dried fruits. Limiting consumption of coffee, tea, and alcohol is recommended.
|Irritable bowel syndrome (IBS)||Regular exercise and improved sleep habits can help relieve symptoms. Although IBS differs from person to person, dieting helps.
Nonmedical usage 
The word borborygmic has been used in literature to describe noisy plumbing. In Ada, Vladimir Nabokov wrote: "All the toilets and waterpipes in the house had been suddenly seized with borborygmic convulsions".
In A Long Way Down (New York: Harper, 1959, p. 54), Elizabeth Fenwick wrote: "The room was very quiet, except for its borborygmic old radiator".
Graham Greene's short story "Alas, Poor Maling" tells the tale of a luckless individual whose borborygmus takes the form of imitating noises that he has recently heard.
