Chronic Vomiting in Cats: Etiology and Diagnostic Testing.

Chronic vomiting in cats is a common presenting problem seen in veterinary practice today. The initial step when presented with a vomiting patient is to differentiate between vomiting and regurgitation or dysphagia. There are numerous causes for chronic vomiting in cats, and therefore a detailed and comprehensive patient history and a systematic diagnostic approach are key steps in determining the cause for vomiting and the most appropriate treatment plan. Common causes for chronic vomiting in cats may include inflammatory bowel disease, food allergy, gastrointestinal motility disorders, neoplasia, and extra-gastrointestinal diseases, such as renal disease, hepatobiliary disease, and hyperthyroidism.
