Which vagal indigestion type is treated by removing foreign bodies?

• A. Type 2
• B. Type 1
• C. Type 3
• D. All types

Answer: (A)

This question hinges on recognizing that vagal indigestion can be caused by a physical obstruction from foreign bodies in the reticulum. When a foreign object lodges in the reticulum or along the reticulo-omasal pathway, it creates a mechanical blockage that prevents normal passage of ingesta and disrupts rumen motility. In this situation, removing the offending foreign bodies directly addresses the root cause, relieves the obstruction, and allows normal motility and flow to resume, which can correct the signs of vagal indigestion.

Other forms of vagal indigestion are driven more by functional loss of coordinated rumen or abomasal/pyloric outflow rather than by a discrete obstructive object. In those cases, simply removing foreign bodies would not fix the underlying motor dysfunction, so the foreign-body removal approach is not the appropriate targeted treatment for them.
