Can gallbladder rupture killl you?

Maybe but rarely: Gallbladders rarely "rupture." contrary to popular misconception, they don't pop like a balloon. They may become so inflamed that they become gangrenous and start leaking. It's not the leak per se that is the problem, but the associated extreme inflammation and damage to surrounding structures. Death is an uncommon occurrence, but may occur in older/sicker patients with other medical problems.

Yes but not often: The gallbladder usually causes significant pain when infected or blocked with stones. It usually doesn't rupture as such, but should it one can be very sick.

If neglected and : Untreated . Rupture of gall bladder will cause massive peritonitis , if untreated along with correction what caused may results in death.
