At present, my country's medical insurance does not include gastroscopy screening items. It is not realistic to carry out gastroscopy screening extensively. It is recommended that the following six types of high-risk groups have gastroscopy every 1-2 years, and he also recommends that patients with gastrointestinal diseases 4-5 years Have a colonoscopy. Six types of high-risk groups:

        1. People over 45 years old;
        2. Patients with old stomach problems, or those who have been infected with Helicobacter pylori;
        3. Those who often eat pickled food and smoked or grilled food;
        4. Those who have stomach polyps or have undergone stomach surgery;
        5. Have a family history of gastric cancer;
        6. People who socialize regularly, drink too much alcohol, or overeating.
