My grandfather has kept me up all night with his violent snoring. is there any way to help this?

Concern: Snoring may be an indication of sleep apnea, a dangerous sleep condition that deprives the brain and other vital organs of oxygen. Have your granpa see his doctor to determine the best approach in managing his snoring. Alcohol and other sedatives amy also contribute to snoring(by relaxing hte back of the throat).

Sleep apnea: If he is overweight, losing weight not only reduces pressure on the airways, the tongue shrinks in size, further opening the airway. Don't let him sleep on his back ( sew a pocket in a t-shirt and put a tennis ball in it ). See an ENT to make sure that there isn't a problem with deviated septum, tonsils or adenoids. Use breathe rite strips. See a dentist to have a custom sleep device made.
