What is listed as a cause of Type 2 vagal indigestion?

• A. Inflammation of the vagal nerve
• B. Blockage of the esophagus
• C. Vitamin deficiency
• D. Bacterial overgrowth in the abomasum

Answer: (A)

Vagal indigestion happens when the nerve that runs to the forestomachs and abomasum (the vagus) isn’t sending normal motility signals. Type 2 specifically is tied to inflammation of the vagus nerve, or vagal neuritis, which disrupts the coordinated contractions and emptying of the stomach compartments. When the nerve is inflamed, the normal rhythmic contractions that move ingesta through the rumen, reticulum, omasum, and abomasum are impaired, leading to the distention and malfunction characteristic of this condition.

Blockage of the esophagus would cause a mechanical obstruction, not a vagal motor problem. Vitamin deficiency can cause various systemic issues but doesn’t directly explain the loss of vagal-driven motility. Bacterial overgrowth in the abomasum is a separate digestive issue and not the neural cause described for Type 2 vagal indigestion.
