What Are Some Symptoms of Erythematous Gastritis?

Symptoms of erythematous gastritis include loss of appetite, nausea, vomiting, and discomfort or pain in the upper abdomen, particularly after eating. Weight loss may occur. Vomiting of blood may occur if there is ulceration. It is also possible for patients with erythematous gastritis to show no symptoms, according to GastroNet.

Causes of erythematous gastritis include toxic chemicals and medications, such as alcohol and aspirin; bile; allergic and immune conditions; radiation; and vascular diseases. Crohn's disease and sarcoidosis can also cause erythematous gastritis, says GastroNet. Treatment starts with removing the cause and acid reduction therapy.

"Erythematous" comes from the Greek "erythros," meaning red. "Gastritis" refers to the inflammation of the stomach lining, says Wikipedia.
