Gastric Bypass
There are several surgeons through U of L. University Surgical Associates. You can reach them at 502-583-8303 or 1-800-872-8033.
As far as I know Dr Allen (which is my surgeon and he is WONDERFUL!) and Dr Jorge Rodreigez (spelling?) have the most experience in this group. They have been doing RNY for many years.
Best of luck to you. I hope a reason and solution can be found quickly.
