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:
This causes symptoms due to the shift of fluid into the intestinal lumen, with plasma volume contraction and acute intestinal distention. [3] Osmotic diarrhea, distension of the small bowel leading to crampy abdominal pain, and reduced blood volume can result. Late dumping syndrome occurs 2 to 3 hours after a meal.
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.
50-60% of total gastric acid secretion occurs during this phase. The gastric phase is a period in which swallowed food and semidigested protein (peptides and amino acids) activate gastric activity. Ingested food stimulates gastric activity in two ways: by stretching the stomach and by gastric contents stimulating receptors in the stomach. [2]
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").
Schistosomiasis causes severe abdominal pain and blood in the urine of the infected, but it is not generally fatal outside of developing countries *The breadth of the range results from a lack of ...
The enterogastric reflex is stimulated by duodenal distension. [2] It can also be stimulated by a pH of 3-4 in the duodenum and by a pH of 1.5 in the stomach. Upon initiation of the reflex, the release of gastrin by G-cells in the antrum of the stomach is shut off. This in turn inhibits gastric motility and the secretion of gastric acid . [1]
