Early spring season is is a good season for gastric ulcer, how to identify early, early treatment, is the key to prevent the emergence of gastric bleeding and other complications. Patients are reminded of the following characteristics of gastric ulcer: chronic, periodic, rhythmic epigastric pain with inconspicuous signs. Some patients (about 10-15%) usually lack typical clinical manifestations. Instead, hemorrhage and acute perforation are their first symptoms. The clinical manifestations of a few special types of ulcers have their own characteristics. Clinical manifestation characteristics Gastric ulcer symptoms are often epigastric pain. Some of them may have various symptoms of dyspepsia, but some of them are also asymptomatic. The common complications include bleeding, perforation, pyloric obstruction, and cancer. Common gastrointestinal symptoms and systemic symptoms include belching, acid reflux, epigastric distention, burning sensation behind the sternum, nausea, vomiting, and poor appetite. Nausea and vomiting mostly reflect ulcers may suggest ulcers in active stage. Frequent vomiting of persistent food suggests pyloric obstruction. Some patients have symptoms of vegetative nerve dysfunction such as insomnia and excessive sweating. The characteristics of epigastric pain of gastric ulcer 1, chronic process: most patients have had the disease for several years, more than a decade or longer. 2, periodic: most patients have recurrent attacks, and the attack period and remission period alternate with each other with changes in seasonal changes, mental tension, emotional fluctuations, dietary disorders or taking drugs related to the onset of the disease. The attack period can be weeks or even months, and the remission period can be months or years. 3, rhythmical: ulcer pain mechanism is mainly related to excessive secretion of gastric acid to stimulate the ulcer surface, so different parts of the ulcer disease pain has a different regularity. Gastric ulcer pain mostly appears half an hour after a meal, lasts 1 to 2 hours, gradually disappears, and the pain recurs after another meal, and so on in a repeated cycle. When gastric ulcers are located at the pyloric duct or coexist with duodenal ulcers, the pain rhythm can be the same as that of duodenal ulcers. However, there are specific types of ulcer disease in which the pain rhythm is not very pronounced, such as ulcers in the elderly and posterior duodenal bulb ulcers. It is worth noting that when there is a sudden change in the rhythm of pain, the disease should be considered to have developed or other complications may arise. 4, the site of pain: gastric ulcer pain is mostly located in the subxiphoid process (commonly known as the fossa of the heart) or to the left, the scope of pain is generally more limited, local pressure pain, but the site of pain, not necessarily the site of the ulcer. When the ulcer reaches the plasma membrane layer or is a penetrating ulcer, the pain may spread to other parts of the body such as the chest, upper left abdomen, upper right abdomen or back. 5, the nature and degree of pain: mostly hunger-like discomfort, dull pain, belching, pressure, burning or sharp pain and stabbing pain, etc.
