A member asked:
Why does a person vomit when the head injury is serious?
A doctor has provided 1 answer
Increased pressure: After a severe head injury people can experience brain swelling or bleeding. In older children and adults the skull has a fixed volume because of closed sutures. Any swelling can irritate the chemo tactic zone of the brain causing nausea and vomiting.
