Patients with duodenal ulcers may achieve some effects through hot compresses, but hot compresses cannot truly effectively treat duodenal ulcers. To effectively treat duodenal ulcers, it is first necessary to detect the presence of Helicobacter pylori infection through the carbon-13 breath test or carbon-14 breath test. If the Helicobacter pylori infection is positive, it is necessary to eradicate Helicobacter pylori using a quadruple therapy containing bismuth. Subsequently, it is important to use proton pump inhibitors or H2 receptor antagonists to inhibit gastric acid secretion, and medications like aluminum magnesium carbonate to protect the gastric mucosa. (The use of medications should be under the guidance of a physician.)
