The pain of patients with duodenal ulcer can radiate from the midline of upper abdomen to other parts, such as back, costal margin and chest.
2 The nature and intensity of pain The nature and intensity of pain in patients with duodenal ulcer are different in different individuals or in different pathological stages of the same individual. Some patients have no typical pain, but only "feeling of oppression", "feeling of bloating" and "burning", and sometimes patients feel similar to hunger. In the absence of complications, the pain of patients is generally not severe, but "dull pain" or "dull pain".
3 The rhythmic pain of duodenal ulcer has a fixed relationship with eating. Pain occurs when the stomach is empty, that is, around 1 1:00 in the morning and 16:00 in the afternoon; In the morning 1:00-2:00. After a meal, the acid is buffered by food and the pain disappears. Duodenal pain rarely occurs in the early morning, because the peak of gastric secretion in patients with duodenal ulcer is in the early morning, and the trough time is in the early morning, so many patients can wake up at night because of pain.
4 Periodicity of Pain The symptoms of duodenal ulcer have a certain periodicity, that is, the symptoms appear day by day, last for several days, weeks or months, and then recur after a period of remission. The periodicity of its onset is often related to the season. Duodenal ulcer often recurs in spring, late autumn and winter, but it is less common in summer. With the passage of time, the ulcer disease is aggravated, and the frequency, severity and duration of the attack may increase, which means that the ulcer disease is aggravated; It may also be reduced and completely cured; If it changes periodically, it is more common in perforation and obstructive ulcer.
