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.
gastric
pertaining to, affecting, or originating in the stomach.
gastric acid
see gastric juice (below).
gastric atony
a large distended stomach lacking in tone as seen in a horse that is a windsucker and continuously swallows air. Predisposes to chronic indigestion.
gastric cicatricial contraction
in horses causes constriction of the stomach and subsequent dilatation of the dorsal sac.
gastric dilatation
see gastric dilatation colic.
gastric dilatation-displacement
see gastric dilatation-volvulus (below).
gastric dilatation-volvulus (GDV)
a syndrome of gastric dilatation leading to volvulus, seen most often in deep-chested, large breed dogs. The etiology is unclear, but aerophagia or overeating are important factors. Gastric hemorrhage and ulceration, hypotensive, hypovolemic shock, and severe electrolyte disturbances contribute to the high mortality. Surgical intervention is often required, cardiac dysrhythmias complicate recovery, and recurrences are common. Called also gastric dilatation-displacement, bloat.
gastric distention
in pigs commonly results in vomiting.
gastric edema
an accompaniment of edema in most organs in cases where edema is widespread; as a sole lesion is significant in the abomasum in cases of arsenic poisoning, ostertagiasis and in edema disease in pigs.
gastric emptying time
the time taken for the stomach to begin to empty of contents; demonstrated in contrast radiography. Delayed in gastric retention due to dysfunction of the pylorus, abnormalities of gastric motility, foreign bodies and systemic diseases.
gastric fluid
see gastric juice (below).
gastric folds
folds in the gastric mucosa and part of the submucosa oriented in the direction of the long axis of the stomach, as they are in the abomasum; they may be few and simple or numerous and tortuous, as in the dog.
gastric foreign body
occurs most commonly in dogs, causing vomiting. Occasionally it may pass into the small intestine, causing partial or complete obstruction with more severe signs of dehydration, shock, and sometimes perforation with peritonitis. A variety of objects may be swallowed, e.g. needles, balls, children's toys, bones, fish hooks and socks, to name a few.
gastric habronemiasis
see habronemiasis.
gastric hemorrhage
caused by gastric ulcer or foreign body. May cause sudden death due to exsanguination, as in pigs with esophagogastric ulcer, or anemia with melena.
gastric hormones
see gastrointestinal hormones.
gastric impaction
in horses fed a diet of coarse indigestible roughage; a cause of subacute colic.
gastric inhibitory polypeptide (GIP)
a tentative gut hormone secreted by the mucosa of the small intestine and playing a part in controlling gastric (inhibition) and intestinal (stimulation) secretion and insulin release (stimulation).
gastric intubation
see intubation.
gastric invagination
a technique for gastric resection in which areas of nonviable gastric wall are folded inward and the remainder sutured together so the necrotic tissue sloughs into the gastric lumen.
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 is of assistance in the digestive process.
gastric motility
varies between the three regions of the stomach, being most active in the antrum, has a basic slow wave motility and a capacity to increase in response to the fullness of the stomach and to decrease with a rise in acidity of the duodenal contents.
gastric mucosa
secretes pepsin (as pepsinogen), hydrochloric acid.
gastric neoplasia
includes adenocarcinoma, carcinoma, benign adenomatous polyps, leiomyomas, plasmacytoma, squamous cell carcinoma.
gastric peptidases
includes pepsin A, trypsin, chymotrypsin, elastase, carboxypeptidase A, carboxypeptidase B.
gastric perforation
in horses occurs secondarily to lesions of the stomach wall, especially squamous cell carcinoma; causes a local peritonitis, often with extension to the spleen.
gastric pits
multiple small depressions in the gastric area of the stomach; a gastric gland opens into the bottom of each pit.
gastric rotation
rotations of the stomach in the embryonic abdomen between its first appearance and its final disposition. In simple-stomached animals such as dogs two rotations are recognized, from the axial tube ventrally and to the left.
gastric rupture
causes sudden cessation of abdominal pain caused by distention; acute endotoxic shock and peracute, diffuse peritonitis kill the animal within a few hours.
gastric squamous-cell carcinoma
the commonest gastric neoplasm in horses. Seen usually in the advanced stages of anorexia and weight loss. Characterized by a fungating mass in the pars esophagea often with secondary implants locally, sometimes widespread in other organs.
gastric torsion
in sows, predisposed by large, sloppy meal and great excitement at feeding time leading to very fast eating. There is a short course with death due to shock and infarction of the stomach wall. See also gastric dilatation-volvulus (above).
gastric ulcer
an ulcer of the inner wall of the stomach. It occurs in all species at a low level but causes little disease. There is a high prevalence in horses racing and in training and is thought to result in impaired appetite. In horses, also caused by nonsteroidal anti-inflammatory drugs. Esophagogastric ulcer in pigs may reach epidemic proportions in some piggeries and cause serious mortalities due to blood loss. Called also gastric mucosal ulceration.
gastric venous infarction
gross lesions of bright red to dark red mucosa; occur in many septicemias, viremias and toxemias in horses and pigs.
gastric waves
peristaltic waves, the pacemakers for antral peristalsis.

Q. What is a best home workout for weight loss around the stomach and waist? I can't go outside a lot, so I do Pilates. I want to know more workouts for weight loss.
A. There is no natural way to target your stomach fat. You can pay for lipo suction, but that is the easy and expensive way out. Plus if you don't put the work into it then you won't appreciate the results as much.
I would focus on a total body fat loss program. Combining cardio with resistance training and sprinkling in some high intensity interval training is a great way to boost your fat loss. Then focus on eating healthier. Start off slowly though so that you don't get overwhelmed and feel like quitting. Go for walks, eat a few meals a day that are healthier with fruits and veggies, then eat regularly for the rest of the day. The point is to gradually transform your habits into healthier ones.

Q. Do japanese in the US still have high risk of stomach cancer? I was born in the US to parents that emigrated from Japan when they were in their late twenties. I know that people in Japan have a very high risk of stomach cancer. Does that mean that as an individual of Japanese origin I also have high risk, although I never were in Japan?
A. Children of immigrants from Japan have lower chance than that of Japanese people living in Japan, and the risk decrease the more time and generations they live outside Japan, but it's still a bit higher than the risk of non-Japanese people living in US.
Q. Which would be the best diet pattern for a woman to have a flat stomach? I am worried about my weight. I have been constantly gaining weight for past few months and I have gained a large belly. I am just 19 years old. I would like to lose weight desperately and I am clueless on the diet pattern that I should be following. Could someone please help me out? Which would be the best diet pattern for a woman to have a flat stomach?
A. Hello. I think some of the previous posts are correct. In addition to increasing your physical activity, it's also very important to monitor how often you go to the bathroom to get rid fat causing waste inside of your stomach. You definitely need to drink lots of water and in order to allow for your body to naturally dispose of these harmful waste.
