Type 4 vagal indigestion is best described as?

• A. Intestinal ileus
• B. Free gas bloat
• C. Omasal transport failure
• D. Abomasal outflow obstruction

Answer: (A)

The main idea here is that vagal indigestion types map to where motility fails along the tract, and Type IV is a functional failure of the intestinal tract itself. When the vagus nerve isn’t coordinating gut movements, the intestines can become hypoactive, leading to an ileus—a functional obstruction where contents don’t move forward despite no physical blockage. This distinguishes Type IV from issues like ruminal gas accumulation (bloat), which would involve the rumen rather than the intestines, or from a mechanical obstruction at the abomasal outflow or a reticulomasal transport problem. So, Type IV vagal indigestion is best described as an intestinal ileus due to impaired gut motility.
