Has anyone ever lost too much weight ?
It happens.
Recently, I can think of two cases.
There's a woman on here named DancingJudge (I think) who had an MGB, lost way too much, and was revised. She's now doing much better.
Also, there was a DSer named Scott who was revised a few weeks ago.
I remember an RNYer (Distal) from a few years ago, but can't remember her name.
Make a long story short, yup.. it' happens. Revision is more difficult operation though. Usually, pancreatic enzymes are tried first before undertaking a revision. Creon is one of the Brands. I believe it is prescription only. Your friend could ask her surgeon or PCP to prescribe it for her.
Lap-Band June 14, 2001. Dr. Rumbaut, Monterrey, Mexico.
Lap-Band removed after 7 years and converted to Sleeve Gastrectomy on July 7, 2008 by Dr. Roslin. I've had three happy healthy Lap-Band babies.... and one VSG baby. 5 years out from revision to VSG. Gained 55 pounds in past 5 months, now considering DS. :(
