I don't necessarily think that GB problems are caused by Meds, but could be? Stress and rich foods are more the culprits, IMHO!!
I had the long version of GB operation and it took a long time to heal. The simple version is better, if they can do it, but all surgery is serious and complications are always possible.
It is possible to treat GB (stones and sand), without surgery, if it is not too far gone, I hope you have a non surgical option, but if not, just remember to do your breathing exercises, while healing.
