Gastritis is surface erosion and inflammation of the gastric mucosa. From a clinical point of view, we distinguish between acute and chronic gastritis, which is most often caused by Helicobacter pylori infection, irritation, autoimmune disorders, reflux of bile into the stomach, and pernicious anemia. It is diagnosed by endoscopy of the upper gastrointestinal tract, x-ray imaging of the upper gastrointestinal tract, complete blood count, fecal occult blood test, and determined by a breath test. According to statistics, out of 160 respondents in the area of Split-Dalmatia County, 53.1% of respondents said they were suffering from gastritis. The gastritis diet includes foods that can provide long-term relief of gastritis symptoms. Eating small meals and drinking enough water can help heal the stomach by reducing the effect of stomach acid. Of the respondents, 113 of them (70.6%), regulate gastritis with proper nutrition, that is mostly with diet. This includes eating fiber-rich foods, cooked and low-fat meals that alleviate the symptoms of gastritis in the long term, and which include cooked and cooked vegetables with low acidity, meat, fish, soups and stews. Besides the risk of developing gastritis can be reduced by following a healthy diet, it is also important to educate the patient that the nurse or technician provides physical and emotional support to the patient and his family and participates in the promotion of the healing process. The patient's knowledge about gastritis is assessed, an individualized teaching plan is developed, and if necessary, the patient should be referred to alcohol counseling and smoking cessation programs.
