After healing from a gastric ulcer, it is not easy to relapse if health education is strengthened. Usually, it is important to rest more, reduce stress, as excessive tension can lead to excitement of the vagus nerve, stimulate gastric acid secretion, and easily induce ulcers. Additionally, improving dietary habits, strictly quitting smoking and drinking, minimizing consumption of strong tea and coffee, and ceasing the use of medications that irritate the gastric mucosa when necessary, such as non-steroidal anti-inflammatory drugs and corticosteroid hormones, are essential. Meals should be on a regular schedule and in controlled portions, avoiding overeating and overdrinking. If gastrointestinal irritation symptoms occur, treatment should be proactive, and if infected with Helicobacter pylori, the bacteria should be actively eradicated. (Use of medications should be under the guidance of a doctor.)
