1, peptic ulcer pain characteristics (1), long-term because the ulcer can heal on its own, but every healing and good recurrence, so there is often a long-term recurrent epigastric pain characteristics. The average duration of the disease is 6 to 7 years, and some can be as long as one or two decades, or even longer. (2), periodic epigastric pain is repeated periodic episodes, is one of the characteristics of such ulcers, especially the duodenal ulcer is more prominent. Epigastric pain episodes can last for a few days, weeks or longer, followed by a longer period of remission. Episodes can occur throughout the year, but they are more common in spring and autumn. (3), the relationship between rhythmic ulcer pain and diet has a clear correlation and rhythmicity. During the day, the period from 3:00 am to breakfast is the lowest secretion of gastric acid, so pain rarely occurs during this time. The pain of duodenal ulcers occurs between meals and continues unabated until the next meal or after taking acid-control drugs. In some patients with duodenal ulcers, pain can occur in the middle of the night due to higher gastric acid at night, especially in those who have eaten before going to bed. The occurrence of gastric ulcer pain is more irregular, often occurring within one hour after a meal, gradually relieved after one to two hours, until the above rhythm reappears after the next meal. (4). The pain site of duodenal ulcer is mostly found in the middle and upper abdomen, or above the umbilicus, or to the right of 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. The pain is about several centimeters in diameter. Because the localization of pain in the cavernous viscera on the body surface is generally not very exact, the location of pain does not necessarily reflect accurately the anatomical location of the ulcer. (5), the nature of pain is mostly dull, burning or hunger-like pain, which is generally mild and tolerable, and persistent severe pain suggests ulcer penetration or perforation. (6) The pain is often triggered or aggravated by mental stimulation, excessive fatigue, careless diet, drugs, climate change, etc. It can be reduced or relieved by rest, eating, taking acid control drugs, pressing the painful part by hand, vomiting, etc. 2. Other symptoms and signs of peptic ulcer (1) Other symptoms In addition to pain in the upper and middle abdomen, the disease may also have other gastrointestinal symptoms such as increased salivation, heartburn, regurgitation, belching, belching, nausea and vomiting. Appetite is mostly normal, but occasionally there may be fear of eating due to painful episodes after eating, resulting in weight loss. Systemic symptoms may include insomnia and other signs of neurosis, or symptoms of imbalance of the vegetative nervous system such as slow pulse and excessive sweating. (2) Signs During the ulcer attack, there may be limited pressure pain in the middle and upper abdomen, the degree is not heavy, and the site of the pressure pain is mostly consistent with the location of the ulcer.
