Hi dpol, I've had my K-pouch since 1978 and have not noticed that it needs to be emptied more often now. Only time it feels like it needs to be emptied more often is when I'm starting to get pouchitis. Then I'll take Mycostat (3 capsules twice a day after meals) for a few weeks and my pouch returns to normal. Eating right makes a big difference for me.
