Gastric pain is a common symptom including acute gastritis, chronic gastritis, peptic ulcer, etc.
Acute gastritis is an inflammation of the inner lining of the stomach. The causes of acute gastritis are: Chemical irritants (aspirin, ammonium chloride, irritating foods), physical irritants (hot foods, spicy foods, etc.) bacteria and bacterial toxins usually introduced by contaminated food or other systemic infections may be followed by acute gastritis. The symptoms of acute gastritis are: severe pain in the epigastrium, nausea, vomiting etc.. If there is an infection involved there will also be diarrhea, fever, etc. (acute gastroenteritis).
Chronic gastritis may follow acute attacks of gastritis or associated with a deficiency of gastric juices, malnutrition, congestive heart failure or uremia, etc. There are no typical symptoms. Clinical manifestations are usually distress or pain in the epigastrium, loss of appetite, and abdominal distention, or symptoms that resemble those of peptic ulcer.
Peptic ulcer. Emotional disturbances are common in patients with peptic ulcer and the recurrences and complications are often associated with psychogenic difficulties. Physiologically it results from the inability of localized areas of the gastroduodenal mucosa to withstand the digestive action of acid-pepsin gastric content. This cause of peptic ulcer is roughly equivalent to the TCM diagnosis of "Liver attacking Stomach", while the more recent introduction of the etiological theory that H-pylori bacteria is responsible for peptic ulcers is reasonably consistent with the TCM differentiation of Stomach Fire.
The patient with a peptic ulcer complains of a cramp like sensation in the epigastrium. It occurs in definite relationship to eating; pain 30 to 60 minutes after a meal will suggest gastric ulcer, while distress two or three hours after eating indicate a duodenal ulcer. The pain is aching, cramp like, burning, and sometimes radiating to the back at the level of the eighth to twelfth thoracic vertebral. Characteristically, it is steady rather than intermittent, continuing for a half hour to several hours. It is more likely to reappear. Nausea and vomiting may also occur. Physical examination reveals localized tenderness in the epigastrium, pain in the left upper quadrant suggests gastric ulcer, in duodenal ulcer it is ordinarily to the right of the midline. Often tender points may be detected at the level of the eighth to twelfth thoracic vertebrae.
