Chronic gastritis and gastric ulcer are both relatively common digestive diseases, and there are certain differences between the two, as follows: 1, chronic gastritis is mainly manifested as vague pain, and there is no regularity, what time may be the symptoms of pain. And gastric ulcer is a certain regularity, especially in 1-2 hours after meals, the pain is more obvious. The duration is also 1-2 hours, and the pain site is relatively fixed. 2, chronic gastritis, mainly manifested as loss of appetite, flatulence, as well as indigestion and other symptoms, gastric ulcer manifested as acid reflux, the upper gastrointestinal tract has a burning sensation and other symptoms. There is still a relatively obvious difference between gastric ulcers and chronic gastritis. However, both gastric ulcer and chronic gastritis need to be identified clinically as they require sufficient attention and timely intervention to avoid aggravation and more serious digestive disorders.
