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.

Patient discussion about gastric

Q. What types of gastric bypass surgeries are there? I heard all sorts of options for gastric bypass are available. What is the most in use?

A. Bariatric surgeries or – gastric bypass surgeries for weight loss fall into three categories: Restrictive procedures make the stomach smaller to limit the amount of food intake, malabsorptive techniques reduce the amount of intestine that comes in contact with food so that the body absorbs fewer calories, and combination operations employ both restriction and malabsorption. The exact one to be done should be decided with the physician according to each patients abilities and pre-operative function level.

Q. how about gastric bypass surgery how does it work on a person and what they half to eat how much weight does the person lose

A. surgery should always be the last answer because it is the biggest change you will do to your body and to your life. theres always a chance that something might go wrong. you have to be on a tight diet meaning one bite of what you eat and that means no sugars, fats, or oils. even if you thought there was no sugar, oil or fat in what ever you eat you will have so much pain in your stomach and you wont stop vomiting which will make it even more painful. the bright side to it is you will lose about 50 pounds in one month which is great but if you dont work out like crazy trying to tone up your muscles you will sag all over and then theres more money thrown out of your pocket doing tummy tucks and tucks for everything else. itall depends on the person. good luck in what ever you do. do your research first

Q. Can gastric problems cause your heart to be enlarged? I am eighteen and my left side of my heart and lung is enlarged. I have done multiple tests to understand why they are enlarged my tests revealed no information, I do not even have asthma. My doctor suggested that I just need to hydrate alot. I have gastric problems everytime I eat even if it is little. Does my gastric problems such a "bubbly feeling" in my stomach and heart burn is affecting my heart size?

A. HI--i am not a DR put because i worked in a hosp as a therapist--the digestive system an the circulatory system are not connected. I suggest to you to change your diet(the things you eat-like pizza an other spicie foods-thy to eat 4hrs before you lay down-eat smaller portions-some times common sence about what you eat will do the trick---good luck-mrfoot56.

coli reductions between matured TFSs or controls ([t.sub.0] = G0/day 22) and gastric acid incubation time ([t.sub.1] = G1, G30, or G120 min) were analyzed with respect to the experimental factors "strain," "fermentation," and "gastric acid incubation time."
On the other hand, hypersecretion of gastric acid by many patients also inhibits the healing process of gastric ulcers.
Vonoprazan (VPZ), a first-in-class potassium-competitive blocker, can inhibit the H+, K+ -ATPase-mediated gastric acid secretion in a reversible and potassium-competitive manner, possessing approximately 350 times more potent inhibitory effects than lansoprazole (LPZ), a typical PPI, in in vitro experiments [16-18].
This pathology is not only common, but at the same time is a costly affair, accounting for use of costly drugs like inhibitors of gastric acid secretion, expensive tests and utilization of time thus causing a real clinical challenge for the patient as well as health care providers10.
Proton pump inhibitors are drugs designed to reduce gastric acid production.
The flavor stimulates saliva production in your mouth and also triggers the production of gastrin, a hormone that tells your stomach to produce gastric acid. More acid in your stomach when you start eating means your food breaks down more fully, which enables your body to absorb more nutrients.
