Gastric distention is the enlargement of the stomach, and can be due to a number of causes. [citation needed]Physiologic (normal) gastric distension occurs when eating. . Distension of the upper stomach stimulates the secretion of stomach acid, while distension of the lower stomach stimulates gastrin secret
The first step in diagnosis is to determine the etiology of abdominal distension. After making a differential diagnosis of abdominal distension, it is important to take a careful medical history. [9] Here are the most common causes of abdominal distension classified as an underlying cause and as a secondary disease. As an underlying disease cause:
Symptoms include burping, abdominal and stomach bloating, along with pain and discomfort. Heavy meals, lying down or bending over after eating should be avoided to help prevent reflux from occurring. The stomach bloating experienced with reflux is intense and will remain until the food is digested all the way.

Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract.The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products.
Tympany or tympanites (sometimes tympanism or tympania), also known as meteorism (especially in humans), is a medical condition in which excess gas accumulates in the gastrointestinal tract and causes abdominal distension. [1] The term is from the Greek τύμπανο (meaning "drum").
Bowel distension, optimal gastric distention is a fundamental prerequisite for CT gastrography data evaluation; collapsed gastric wall may mimic disease or obscure underlying pathology. Negative oral contrast medium with effervescent granules is effective for optimal gastric distension.
