I had my gall bladder removed at the same time as my bypass as i had gall stones. I had 8 keyhole incision wounds in total, which seemed more than some of my friends who haven't had it removed, but i'm not sure if this is why.
Having it removed did not impact on my recovery / healing process of my bypass and i'm glad i had it all done at once rather than having to go back in for a second surgery.
Although i've had no problems from my bypass site i am still having discomfort from my gall bladder site. I still find it difficult to lift and carry heavy objects and can't do any exercise that involved jiggling about. Apparantly this does happen for some patients and cann take a couple of years to improve, which is very frustrating (i'm 16 months post op). I have also developed an issue with codeine medication. Despite taking it for twenty years, after my op it has suddenly started causing bile duct spasms, whic feels similar to passing a gall stone. But, i still don't regret having it done as the gall stones were awful and would have got worse with the rapid weight loss.
