Peptic ulcers include gastric ulcers, duodenal ulcers, complex ulcers, etc. There can be many complications, such as gastrointestinal bleeding, and if not healed over a long period, degeneration may occur, leading to the development of gastric cancer. Therefore, peptic ulcers must be treated promptly. As for the principles of treatment, they should be determined based on specific symptoms and whether there is a Helicobacter pylori infection. If there is a Helicobacter pylori infection, the general approach is to use quadruple therapy for antibacterial treatment; if there is no Helicobacter pylori infection, treatment generally focuses on symptomatic relief, such as suppressing stomach acid, protecting the mucosa, and increasing gastric motility, etc. At the same time, it is essential to pay attention to regular eating and living habits, eating on a regular schedule or having small, frequent meals. Avoid overeating, as well as stimulating substances like cold, greasy, and spicy foods. Additionally, it is important to keep warm and get plenty of rest.
