Official advice used to be 7 weeks off for any abdominal operation, but I would guess it has been personalized over the years. I was in hospital for 5 days, then went home and had to wait in for the district nurse a couple of times. I'm a nurse too, so I had to wait until she had been because she almost caught me in my cycling kit a couple of times.
Essentially, don't be daft. Give it time to heal, take a couple of weeks off any strenuous activity, check with the district nurse about when your clips come out, and don't do any heavy lifting until you are well healed.
