There are many causes of gastric pain, and incidental pain is generally common in chronic gastritis and peptic ulcers; neurosis, gastric cancer, and chronic cholecystitis can also manifest as epigastric pain and discomfort. The cause of the pain is clearly identified by the differential diagnosis of gastroscopy, gastric mucosal tissue biopsy, H. pylori examination and gallbladder ultrasound.
Chronic gastritis is divided into superficial gastritis and atrophic gastritis, both of which have no specific clinical manifestations and have an insidious onset. The two have no specific clinical manifestations and have an insidious onset. They may present with stomach pain, fullness and discomfort with belching, acid reflux, and other symptoms, commonly after meals.
Peptic ulcers, which have deeper mucosal damage than chronic gastritis, are divided into gastric ulcers and duodenal ulcers. Epigastric pain is often triggered or aggravated by mental stimulation, fatigue, improper diet, medication, weather changes, etc. The duration of the disease is long and the pain comes on periodically with typical rhythmic manifestations: duodenal ulcers are painful when hungry, mostly occurring 3 hours after a meal and relieved after eating; gastric ulcers often occur within an hour after a meal and disappear by the next meal.
In the early stages of gastric cancer, vague pain in the upper abdomen and loss of appetite are also seen, requiring vigilance to avoid progression and timely consultation to clarify the cause.
