I feel such a looser

Please I  gain 40 pounds, Throwing up everytime that i eat protein, being only fed by bad carbs easy to digest, had rny in 2004, depress, any help thanks claudia

I would consult your surgeon.  Is it possible you have a stricture?  That could be why you arent able to easitly digest more solid foods.  Throwing them up is not normal.  If that is the case, its an easy fix. 

What is a stricture?  I keep seeing that word and not sure of the meaning!  Thanks!

A stricture means that there's too much scar tissue at the exit of the pouch to the intestines.  The hole is too small to allow all but soft foods and liquids to pass.
