inflammation of the lining of the stomach. Gastritis is one of the most common stomach disorders, and occurs in acute, chronic and toxic forms. Its clinical manifestation is vomiting. In veterinary medicine, the pathogenesis, clinical findings and postmortem lesions are poorly defined and are, in many cases, based on functional rather than on structural changes.
severe gastritis caused by food poisoning, overeating or bacterial or viral infection, and often accompanied by enteritis. The outstanding sign of acute gastritis is abdominal pain.
an immune-mediated disorder described in dogs with systemic lupus erythematosus; associated with antiparietal antibodies.
an inflammation of the stomach that may occur repeatedly or continue over a period of time.
chronic atrophic gastritis
rare in dogs; associated with mucosal thinning, loss of parietal cells, mucosal metaplasia and atrophy of gastric glands.
inflammation of the gastric wall by Clostridium perfringens.
diffuse infiltration or discrete nodules of eosinophils in the stomach wall occur rarely in dogs. May be immune-mediated, due to allergy or parasites.
giant hypertrophic gastritis
excessive proliferation of the gastric mucosa, producing diffuse thickening of the wall; inflammatory changes may be associated. Weight loss, vomiting, diarrhea, hematemesis and hypoalbuminemia occur. Occurs in humans, dogs (particularly Basenjis), mice and nonhuman primates. Called also Ménétrier's disease.
see gastric habronemiasis.
rare cases occur in dogs in association with amyloidosis.
hypertrophic glandular gastritis
see giant hypertrophic gastritis (above).
seen rarely in dogs, usually associated with fungal infection.
