Generally normal gastritis is atrophic and non-atrophic. Atrophic gastritis is the damage of gastric mucosa caused by organic atrophy of gastric mucosa. Non-atrophic gastritis is mostly due to acute lesions of the gastric mucosa, mostly due to food stimulation or long-term oral anti-inflammatory painkillers on the gastric mucosal stimulation damage. Generally, non-atrophic gastritis has milder symptoms than atrophic gastritis, and is usually characterized by acid reflux, heartburn, and hiccups. Therefore, once diagnosed with non-atrophic gastritis, it is further necessary to check for Helicobacter pylori to see if there is any Helicobacter pylori infection. If the treatment of gastritis is simple, H. pylori is not eradicated, the treatment effect is not good. In addition to medication, diet is also very critical, the diet needs to be a light diet, avoid overeating, avoid spicy stimulation, raw, cold, hard food, eat more fresh fruits and vegetables, drink more water, pay more attention to rest.
