What is the reason for projectile vomiting and nausea due to elevated intracranial pressure?

18 February 2014 1 4K Report

Elevated intracranial pressure is often associated with vomiting. I would like to know how the pressure triggers the vomiting.

Cory D Bovenzi

It may be due to transmitted pressure to the area postrema in the medulla, which is one area responsible for vomiting. The authors of Irwin and Rippe's Intensive Care Medicine agree.
