Gastric juice mainly contains hydrochloric acid and pepsin.

Gastric acid is about 0. 5 % hydrochloric acid ( HCl ), which lowers the pH to the desired pH of 1-3.

* Gastric H < sub > 2 </ sub > receptor blockers ( such as ranitidine, famotidine and cimetidine ) can reduce gastric secretion of acid.

* Gastric acid secretion and pH.

Gastric acid is produced by cells lining the stomach, which are coupled to systems to increase acid production when needed.

Gastric acid is produced by parietal cells ( also called oxyntic cells ) in the stomach.

Gastric acid secretion happens in several steps.

Gastric acid is then secreted into the lumen of the oxyntic gland and gradually reaches the main stomach lumen.

Gastric acid production is regulated by both the autonomic nervous system and several hormones.

* Gastric acid

* Gastric Bypass procedures such a Duodenal Switch and RNY, where the largest acid producing parts of the stomach are either removed, or blinded.

Gastric acidity is responsible for the destruction of the majority of ingested bacteria.

** Gastric lavage, commonly known as a stomach pump, is the insertion of a tube into the stomach, followed by administration of water or saline down the tube.

< ref name =" lethal "> </ ref > Gastric evacuation or lavage is " seldom " indicated.

Hereditary Diffuse Gastric Cancer ( HDGC ) has recently been identified and research is ongoing.

* Gastric adenocarcinoma is a malignant epithelial tumor, originating from glandular epithelium of the gastric mucosa.

Gastric adenocarcinoma, especially at the pylorus, is the most common source.

Gastric distension is bloating of the stomach when air is pumped into it.

Gastric distension is potentially dangerous since it can cause the contents of the stomach to come up the esophagus ( gullet ) and spill back down into the lungs.

Gastric dilatation volvulus or bloat is a medical condition in which the stomach becomes overstretched by excessive gas content.

Gastric decontamination may be of little benefit given the risk of seizures and aspiration but activated charcoal is recommended.

Gastric feeding tubes have a variety of complications that can occur, though the overall rate of complication is about 1 %.

Gastric bypass is indicated for the surgical treatment of morbid obesity, a diagnosis which is made when the patient is seriously obese, has been unable to achieve satisfactory and sustained weight loss by dietary efforts, and is suffering from comorbid conditions which are either life-threatening or a serious impairment to the quality of life.

* Gastric bypass is one of four types of operations for morbid obesity.

Gastric aspiration and or lavage, where a tube is inserted into the stomach via the nose in an attempt to determine if there blood in the stomach, if negative does not rule out an upper GI bleed but if positive is useful for ruling one in.

* Gastric inhibitory peptide ( or Glucose-dependent insulinotropic peptide ) is a digestive hormone

Gastric stasis refers to the retention of fluid in the stomach.

Gastric lavage ( stomach pumping ) and the administration of activated charcoal can be used to reduce the stomach's absorption of the ingested material.

* Gastric lavage The process of cleaning the contents of the stomach

Gastric ulcers are most often localized on the lesser curvature of the stomach.

Gastric juice in the stomach starts protein digestion.

* Gastric inhibitory peptide ( GIP )-is in the duodenum and decreases the stomach churning in turn slowing the emptying in the stomach.

** Gastric fistula: from the stomach to the skin surface

Gastric cancers due to smoking mostly occur in upper part of stomach near esophagus Studies are variable with respect to stomach cancer and alcohol consumption.

* Gastric antral vascular ectasia, dilation of small blood vessels in the last part of the stomach.

Colonization of the stomach lining by this bacterium can lead to Gastric ulcer and cancer.

* Gastric torsion (" Bloat "): A painful and often fatal twisting of the stomach occurring in large or deep-chested breeds.

Gastric bypass procedures ( GBP ) are any of a group of similar operations that first divides the stomach into a small upper pouch and a much larger lower " remnant " pouch and then re-arranges the small intestine to connect to both.
