Gastric ulcers are a common upper gastrointestinal disease. The main causes are related to Helicobacter pylori infection, poor dietary habits, medication irritation, or chronic mental stress. Incomplete treatment of gastric ulcers can lead to recurrent episodes, and in severe cases, may evolve into gastric cancer. Thus, it is crucial to develop good dietary and living habits while undergoing proper treatment. Dietarily, it is advised to eat light, easily digestible foods such as soft, mushy rice, noodles, porridge, and fresh fruits and vegetables. Meat products should be cooked in a light manner, avoiding overly greasy or spicy foods. Additionally, quitting smoking and alcohol and maintaining a positive mood are also beneficial.
