I felt rather ill for a while after my surgery (and my shoulder still hurts now and then to do this day, 5 years ago), but after a few weeks I got better than I was when my gall bladder was still present and dysfunctional.
Unfortunately I developed IBS, and also have pretty severe reflux that is set off by certain foods. If I miss a few hours sleep, have caffeine or complicated foods in the morning, or am stressed I am prone to nausea and soul-searing pain that starts on my right side and migrates to the center. Bacon is one of the foods I can’t have, it causes 24 hours of reflux without fail even if it’s just a small piece. Reflux was a symptom when I still had my gall bladder, but IBS started after it was removed.
At least now I won’t get another gall stone, and perhaps I’m only complaining because I was lucky enough not to have an emergency / life-threatening gall bladder issue to begin with. I have heard most people who have their gall bladders out do not return to normal GI functioning, contrary to what I was told by my doctors beforehand. It may be that positive or negative thinking can skew the results, as the GI tract is highly responsive to emotion, but it did not work in my case.
