Plasmacytic Gastritis

Gastritis is an acute or chronic gastrointestinal disorder and a very common reason for pet owners to visit a veterinary clinic with a vomiting or diarrheic pet (sometimes involving blood). Acute gastritis is most commonly caused by ingesting spoiled food, toxic substances, foreign bodies, medications, or food that is unusual for the animal. If left untreated, acute gastritis can develop into a chronic condition, which is much more difficult and time-consuming to treat.

Chronic gastritis in dogs is classified based on the types of cells found in the inflamed mucosa (eosinophilic, lymphoplasmacytic, granulomatous, or follicular lymphoid tissue). We can determine which type of gastritis is affecting your pet by performing a gastroscopy and taking a sample for cytological examination.

One of the most frequently diagnosed types is plasmacytic gastritis. While it does not have unique symptoms, a cytological exam reveals an increased number of plasma cells and severe inflammation, typically characteristic of chronic patients. Chronic conditions are managed through a specialized diet and medication, requiring patience and consistent cooperation with your veterinarian.

If your pet experiences acute vomiting (or vomiting more than once a week), diarrhea (which may contain blood), dark stools, a decrease or loss of appetite, or lethargy, it is essential to contact a veterinary clinic immediately. Prompt action ensures an accurate diagnosis and the most effective treatment for your pet.
