Difference between gastritis and gastric ulcer

Gastritis is the inflammatory reaction of the intestinal mucosa caused by various stimulating factors, which damages the barrier function of the intestinal mucosa of the patient and changes the structure of the intestinal mucosa glands, but does not show the occurrence of mucosal rupture and ulceration. Gastric ulcer is the damage or damage of the intestinal mucosa caused by gastric acid or Helicobacter pylori infection. So that the patient's stomach acid and pepsin will digest their own gastric mucosa tissue, so that it will show ulcer focus, so it is recommended that the patient should do gastroscopy to clarify the condition.
