Gastric ulcer is a common disease with symptoms that include the following: Age: The age of onset of gastric ulcer patients is on average about ten years older than that of duodenal ulcer patients. There are relatively more people over the age of forty. Pain: The typical symptoms of gastric ulcer are characterized by upper abdominal pain, which is often referred to as “stomach pain”. The pain occurs after a meal, due to the increased gastric power after the meal, grinding food is the stimulation of the ulcer is enhanced, until the next meal the pain can be gradually relieved, this is the so-called “rhythmic” pain, that is, “eating – pain – relief”. The pain can sometimes radiate to the corresponding area in the back. It may be accompanied by bloating and belching. Eating alkaline foods such as soda crackers can also relieve the pain. Patients are also generally sensitive to raw, cold, sour and spicy irritating foods, and drinking alcohol can aggravate pain or induce pain. An overfull diet can aggravate pain, and some patients even voluntarily reduce their food intake for fear of post-meal pain and consequent weight loss. Seasonality: The abdominal pain symptoms of typical gastric ulcer patients also have a seasonal pattern, occurring in the fall, winter, or winter-spring, and it is common for the pain to recur and remit over many years. This is known as “cyclical” pain. It may resolve on its own. It may worsen with stress and exertion. Bleeding: Gastrointestinal bleeding occurs when the ulcer erodes the blood vessels, resulting in vomiting of blood, black stools, etc., requiring emergency treatment. In severe cases, perforation may occur, and sudden onset of severe abdominal pain, which is unbearable, also requires emergency treatment. Some patients present with bleeding and perforation during the first ulcer attack. A significant proportion of patients with gastric ulcers who take aspirin and NSAIDs have no abdominal pain, and these “silent ulcer” ulcers are more likely to develop complications. These “silent ulcer” ulcers are more likely to develop complications, and the complications of medication-induced ulcers are more severe than in patients with no history of medication use. Therefore, once the above symptoms are detected, the existence of ulcers should be suspected and should be promptly examined and regularly treated.
