What prevents people in a coma from waking up?

317 views

Probably a very stupid question but I can’t wrap my head around it. For instance if someone had head trauma, why can they not wake up after a few days or so? What is it that keeps them unconscious for such a duration of time with nothing to wake them?

Edit: i’m confused why this got so many upvotes but thanks😁

There are lots of reasons to be in a coma. Direct brain injury from trauma is only one. The first step in managing coma is finding out the cause, reversing it if possible, and managing complications that happen when someone cannot care for their body.

For direct brain injuries we talk about primary and secondary injury everything we do in the hospital as neurosurgeons is trying to protect the healthy brain from the injured brain which swells.
