My experience was the other way around.. I had lap band surgery 5 years ago.. then I came down with a very nasty auto-immune disease. I had no idea of the connection until I read the following.. which I pasted into my wordpad from a lap band website.... it was only a few days ago, and I cannot seem to find the source in my favorites.. I'll keep looking.. Lizzie
Silastic reaction
It is possible that the material of the Band could create some type of body immune reaction that stimulates a separate disease process such as arthritis or Systemic Lupus Erythematosis (SLE). However the Band is made of a silicone elastomer which is completely non-reactive to the body tissues, as far as it has been possible to determine. The same type of material has been in use in a number of implanted medical devices over time, and no problems with tissue reaction have been demonstrated. Here again, the early data is reassuring but no true long-term information exists.
