For what it's worth, I'm a reasonably fit 47 year-old who had a laparoscopy 4 days ago for severe endometriosis. And I agree to ask your doctor, but I find I usually got the standard "everyone is different" response, so I can just share my experience. As soon as I could, I made sure to move around a lot in my home and have walked laps around my kitchen island while on the phone. I gained 8 lbs. after the procedure, and only this a.m. did I notice that start to reduce. But best news, I went for a walk outside for the first time this a.m. (less than a mile), with the only real side-effect (so far) of increased shoulder pain, probably from moving the gas around a bit as well as it being windy/cold. Hope this helps you plan and good luck with your procedure.
Ask your doctor. Good luck.
