Gastric ulcer is how is it?

Located in the cardia to the pyloric ulcer is called gastric ulcer among chronic (gastric ulcer, GU), is a peptic ulcer. Peptic ulcer (peptic ulcer) can occur in the stomach, duodenum, may also occur in the lower esophagus, stomach - jejunum near the anastomosis and Meckel diverticulum with ectopic gastric mucosa. The formation of these ulcers are related to gastric acid and pepsin digestion on, it is called peptic ulcer. Most of the disease in the stomach and duodenum (98% -99%). About 10% of the population who may be suffering from the disease in a lifetime, it is a frequently occurring and common diseases in the digestive surgery plays an important role. Duodenal ulcer, gastric ulcer disease is more common than about 4:1. The two also has much in common: both etiology and pathogenesis of gastric acid and pepsin on the "self-digestion" as a direct factor, pathology, on two similar; in a few patients can be simultaneously both of them, that compound ulcers. There are also many differences between the two, such as age of onset is different from gastric ulcer occurs in 40 to 60 years old, and duodenal ulcers occur in the young average age of onset of gastric ulcer than duodenal ulcer around for 10 years , duodenal ulcer onset and the spirit of the relatively close relationship between neural factors, "O" type blood type, blood group antigens in saliva without liver cirrhosis, hyperparathyroidism is also susceptible to duodenal ulcer, and drugs such as aspirin, corticosteroids, alcohol, etc. are mostly caused by gastric ulcer; disease mechanism, the basis of duodenal ulcer and gastric acid secretion of gastric acid were higher than normal, while patients with gastric ulcer and normal gastric acid secretion similar or even lower than normal; the possibility of malignant gastric ulcer, and a few non-malignant ulcer, the clinical performance of the two are not the same, mostly duodenal ulcer pain and night pain, hunger, and stomach ulcer pain, mostly after dinner, surgical treatment of duodenal ulcer on the effect of vagotomy is better than gastric ulcer. Therefore suggested that the two are different diseases.
