The preferred test for duodenal ulcers is upper gastrointestinal imaging, which can be performed with oral barium or with oral pantethine. If necessary, gastroscopy can be chosen to visually detect the site and size of the duodenal ulcer lesion, and biopsy can also be performed to clarify the pathology. Ulcers are a common benign disease in which the patient’s main symptom is epigastric pain, especially noticeable on an empty stomach, which occurs more often among young patients. Recurrent ulcers are associated with significant loss of appetite and weight loss. Ulcers are also prone to serious complications, including ulcer perforation, bleeding, scarring pyloric obstruction formation, and in severe cases, further surgical treatment options. You should pay attention to a reasonable diet, not overeating, and also pay attention to the appropriate administration of drugs to protect the gastrointestinal mucosa and anti-ulcer therapy.
