It is bad to hold your pee if you hold it for too long.
Holding your pee won't kill you unless it gets to the point of kidney failure.
You can cause kidney failure and kidney disease as well as bladder infections and Urinary Tract Infections from holding in your pee.
You should never hold in your pee any longer than you have too and if you have to pee you should go as soon as you can.
Holding your pee in for 10 to 20 minutes every once in awhile is likely to not cause any harm but if you continue holding in your pee too long and too often then it could lead to bladder infections, kidney infections, kidney disease and even sometimes kidney failure.
You cannot die directly from holding in your pee. But holding in your pee can cause health problems such as bladder infection, Urinary Tract Infections, and Kidney disease which could kill you if not treated.
The kidney disease is what would ultimately kill you if you do develop kidney disease from holding in your urine.
You should always avoid holding in your pee for too long because it can cause health problems.
Always get to a toilet as soon as possible to relieve yourself.
