Gastric ulcers are a disease characterized by defects in the gastric mucosa. The main symptoms include stomach pain, bloating, nausea, vomiting, belching, and acid reflux. These defects in the gastric mucosa can be observed through gastroscopy, allowing for a diagnosis of gastric ulcers. The treatment primarily focuses on suppressing acid, protecting the stomach, and enhancing gastric motility. Additionally, it is important to test for Helicobacter pylori. If the test for Helicobacter pylori is positive, standardized treatment against Helicobacter pylori should be administered. This bacterium is a primary cause of gastric ulcers. With proper treatment, gastric ulcers generally heal within six to eight weeks. During the treatment period, dietary considerations are crucial; it is important to consume easily digestible foods and avoid fatty, rich, and hard-to-digest foods to aid in the recovery from gastric ulcers.
