this is possible with age but can also be a sign of other nerve problems in the bowel. if there is stool leakage this is sometimes due to a loosening of the sphincter muscle that should prevent this. this may be muscular but is sometimes nerve related. I would see a gastroenterologist to be sure. They can take a look at the tone of your sphincter and also make sure there aren't any small tracts called fistulas that cause stool to leak when you push.
good luck please press accept if no more questions
