How long a patient with duodenal ulcer can live usually varies from person to person, depending on the severity of the disease, whether the treatment is appropriate, the patient’s own condition and many other factors. The disease is a common benign lesion of the digestive system, usually not life-threatening, and in most cases can be cured, so patients are not advised to worry too much. If a patient has been diagnosed with duodenal ulcer, he or she should go to the hospital in a timely manner. Early treatment can help to reduce pain, shorten treatment time, prevent complications and reduce the possibility of recurrence. If the condition is mild and does not cause other serious complications, antacids, antisecretory drugs and gastrointestinal motility drugs can be applied under the guidance of professional doctors to help reduce the activity of pepsin and the digestive effect of gastric juice, and to neutralize gastric acid, protect gastric mucosa and promote gastric emptying, etc. Common drugs include ranitidine, omeprazole, magnesium carbonate, etc. Patients with mild cases usually have a better prognosis and no impact on survival if they actively cooperate with treatment, pay attention to diet and ensure rest. If the disease is severe and the patient does not undergo timely standardized and effective treatment, it may lead to serious complications such as bleeding, perforation and obstruction, which are more dangerous. In this case, timely surgical treatment is needed to improve survival and quality of life.
