Tylenol or Aleve?
NSAIDs are strong potential stomach irritants for anyone, and after having the RNY, that's an even bigger problem. Tylenol, on the other hand, works through the liver. This can also be a problem for ANYONE, but it's potential problems aren't any greater post-op than pre-op, since the RNY doesn't directly affect the liver. (However, rapid weight loss CAN adversely affect the liver, so ANY pain reliever should only be taken in moderation post-op.)
