Prayers for a speedy recovery, badger.
The thing that bother me is that this has become a routine proceedure. Especially in women.
As young as she is is also a curious factor and probably diet related.
For example a lot of women that were on the Jenny Craig diet had gall bladder issues (knew a few)
It may be time to reevalute what her diet consists of, without the gall bladder, other symptoms may develope.
I'm not a Dr. but know there is always a cause and effect. Doctors have a liecence to practice medicine but don't always tell everything they know unless confronted.
