Which term describes abomasal reflux syndrome?

• A. Internal vomiting
• B. Regurgitation
• C. Bloat
• D. Diarrhea

Answer: (A)

Abomasal reflux syndrome presents as regurgitation of the stomach’s contents rather than true vomiting. In this condition, contents from the abomasum flow back up into the esophagus and may be expelled through the mouth without the retching and abdominal contractions that define vomiting. This passive expulsion is what clinicians refer to as internal vomiting in large animals. So the key idea is distinguishing regurgitation from vomiting: regurgitation (internal vomiting) is a passive process due to reflux, while true vomiting involves retching and abdominal effort. The other options describe different GI problems—bloat is gas distension of the rumen/abomasum, and diarrhea is loose stool—neither of which characterize abomasal reflux syndrome.
