A stomach rumble, also known as a bowel sound, peristaltic sound, abdominal sound, bubble gut or borborygmus (pronounced / ˌ b ɔːr b ə ˈ r ɪ ɡ m ə s /; plural borborygmi), is a rumbling, growling or gurgling noise produced by movement of the contents of the gastrointestinal tract as they are propelled through the small intestine by a series of muscle contractions called peristalsis.

Relative position of the heart and stomach in the human body. Symptoms can be as follows. [10] [11] They are periodic, and occur only during an "episode", usually after eating.
While this relaxation may be voluntary, the overall process of rumination is still generally involuntary. Relaxation due to intra-abdominal pressure is another proposed explanation, which would make abdominal compression the primary mechanism. The third is an adaptation of the belch reflex, which is the most commonly described mechanism.
The condition is characterised by chronic gastrointestinal symptoms relating to excessive gas retention including abdominal bloating with distension, flatulence, audible gurgling sounds, and chest and abdominal discomfort. [2] Some with the condition are also unable to vomit, or can only do so with great difficulty.
The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine.

Gastroparesis (gastro- from Ancient Greek γαστήρ – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period of time.
The stomach does vary in size but its J shape is constant. [citation needed] The stomach lies in the upper part of the abdomen just below the left rib cage. The term gastropathy means "stomach disease" and is included in the name of the diseases portal hypertensive gastropathy, hyperplastic hypersecretory gastropathy (Ménétrier's disease ...
A gastric emptying scintigraphy test involves eating a bland meal that contains a small amount of radioactive material. An external camera scans the abdomen to locate the radioactive material. The radiologist measures the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal. The test can help confirm a diagnosis of dumping syndrome.
