One of the most important considerations when managing these patients is to accurately differentiate regurgitation from vomiting. Regurgitation is one of the most commonly misinterpreted signs in veterinary medicine. Obtaining a thorough history is of paramount importance when differentiating the two.
Not only are different organs involved, but also different diagnostic techniques and therapeutics are warranted. Regurgitation can be associated with a multitude of different disease processes, therefore, establishing the underlying cause is essential. Your pet may be very mildly affected, with infrequent and/or subtle signs, or very severely affected, with signs that warrant hospitalization for support and a more aggressive work-up.
