Grade I atrophic gastritis is not serious. Atrophic gastritis refers to the atrophy and reduction of the gastric mucosa and glands, and it manifests with symptoms like stomach discomfort, bloating, stomach pain, and loss of appetite. For those with atrophic gastric cancer, it is important to control the diet, avoid overeating, and abstain from spicy, raw, greasy, and irritating foods. This type of chronic digestive system disease, if not properly managed, can frequently relapse and has the potential to become malignant. If the condition can be controlled and does not frequently recur, it generally does not have a significant impact on the body.
