Gastric ulcers and duodenal ulcers are generally referred to collectively as peptic ulcers, sometimes abbreviated as ulcers. The stomach acid (hydrochloric acid) and pepsin (a type of enzyme) that originally digest food instead digest their own stomach and duodenal walls, thereby damaging the mucosal tissue, which is the main cause of peptic ulcers. The pain of duodenal ulcers is mostly found in the middle and upper abdomen, either above the umbilicus or to the right above the umbilicus; the location of gastric ulcer pain is also mostly in the middle and upper abdomen, but slightly higher, or to the left of the subxiphoid and subxiphoid processes. The pain is about several centimeters in diameter. Because the localization of pain in the cavernous viscera is generally not very precise on the body surface, the location of the pain does not necessarily reflect the anatomical location of the ulcer accurately. Dietary considerations for peptic ulcer patients: 1. chew slowly and avoid anxious food, chewing can increase saliva secretion, the latter can dilute and neutralize gastric acid and may have the effect of improving the gastric mucosal barrier; 2. eat regularly and regularly to maintain the rhythm of normal digestive activity; 3. when the acute activity period, it is appropriate to eat less and more meals, just 4-5 times a day, but once the symptoms are controlled, it should be encouraged to more quickly 4, diet should pay attention to nutrition, but there is no need to specify special recipes; 5, avoid snacking between meals, and should not eat before bedtime; 6, in the acute activity period, should stop smoking and alcohol, and avoid coffee, strong tea, thick broth and chili acid vinegar and other stimulating condiments or spicy drinks, as well as drugs that damage the gastric mucosa; 7, diet is not full, in order to prevent excessive expansion of the gastric sinus and increase the secretion of gastrin. secretion.
