gastric

 [gas´trik]
pertaining to, affecting, or originating in the stomach.
gastric analysis analysis of the stomach contents by microscopy and tests to determine the amount of hydrochloric acid present. The tests performed are of value in diagnosing peptic ulcer, cancer of the stomach, and pernicious anemia. Gastric secretions are collected by continuous or intermittent aspiration via nasogastric tube. There is a wide overlap of the ranges of normal and abnormal values; hence intermediate values are not indicative of pathology. A total absence of acid (pH above 6.0) occurs in almost all cases of pernicious anemia and in some patients with advanced gastric carcinoma. Hypersecretion of hydrochloric acid is characteristic of zollinger-ellison syndrome, which is marked by intractable, sometimes fulminating peptic ulcer, gastric hyperacidity, and gastrin-secreting pancreatic tumors.
gastric bypass surgical creation of a small gastric pouch that empties directly into the jejunum through a gastrojejunostomy, thereby causing food to bypass the duodenum; done for the treatment of gross obesity.
gastric juice the secretion of glands in the walls of the stomach for use in digestion. Its essential ingredients are pepsin, an enzyme that breaks down proteins in food, and hydrochloric acid, which destroys bacteria and helps in the digestive process.

At the sight and smell of food, the stomach increases its output of gastric juice. When the food reaches the stomach, it is thoroughly mixed with the juice, the breakdown of the proteins is begun and the food then passes on to the duodenum for the next stage of digestion.

Normally the hydrochloric acid in gastric juice does not irritate or injure the delicate stomach tissues. However, in certain persons the stomach produces too much gastric juice, especially between meals when it is not needed, and the gastric secretions presumably erode the stomach lining, producing a peptic ulcer, and also hinder its healing once an ulcer has formed.
gastric partitioning a procedure of the treatment of morbid obesity consisting of the creation of a small pouch in the proximal stomach by two rows of staples, which are deliberately interrupted at one point to allow passage of food from the pouch to the rest of the stomach. This procedure is rarely done today because of its high failure rate. The two favored operations are the gastric bypass and the vertical banded gastroplasty.

juice

 [jo̳s]
any fluid from animal or plant tissue.
gastric juice see gastric juice.
intestinal juice the liquid secretion of glands in the intestinal lining.
pancreatic juice the enzyme-containing secretion of the pancreas, conducted through its ducts to the duodenum.
prostatic juice the liquid secretion of the prostate, which contributes to semen formation.

gas·tric juice

the digestive fluid secreted by the glands of the stomach; a thin colorless liquid of acid reaction containing primarily hydrochloric acid, chymosin, pepsinogen, and intrinsic factor plus mucus.

gastric juice

n.
The colorless, watery, acidic digestive fluid that is secreted by various glands in the mucous membrane of the stomach and consists chiefly of hydrochloric acid, pepsin, rennin, and mucin.

gastric juice

The watery mixture of hydrochloric acid, pepsin and mucin secreted by the glands in the lining of the stomach. Gastric juice has a powerful digestive action on protein and is also protective against many infective organisms.
