HELP!!! FRIEND IN SERIOUS TROUBLE FOLLOWING WLS!!!

HI OH FAMILY,

I HAVE A FRIEND WHO HAS RNY WLS 5YRS AGO.  SHE RECEIVED HER LABS AND WAS NOTIFIED THAT ALL OF HER LEVELS ARE WAY BELOW WHERE THEY SHOULD BE.  SHE HAS BEEN TO SEVERAL DOCTORS AND WAS ADMITTED TO THE HOSPITAL A FEW TIMES BUT THEY STILL CAN'T FIND OUT WHY SHE IS LOSING BLOOD & LEVELS WON'T GO UP.  SHE JUST GOT ANOTHER SET OF LAB RESULTS YESTERDAY AND DISPUTE TAKING MORE SUPPLEMENTS PER SCRIBED  BY HER DOCTORS, HE LEVELS WERE DOWN EVEN MORE. HERE IS A LIST OF WHAT I KNOW OF HER LEVELS:

Oh, I asked her what she thought went wrong and she did say that for the past two years she wasn't taking all of her vitamins or enough protein but how can she get her levels back to normal?

Total Iron  13
Iron Sat       3
HCT       25.8
MCV       62.5
Hemoglobin   7.0
All Vitamins are below where they should be
Vitamins B    254
Protein is also low

The doctors feel that she is loosing blood somewhere but they can't find where.  She has had numerous tests and procedures but nothing is working.  She is getting very worried and depressed.  HAS ANYONE EXPERIENCED THIS?  WHAT DID YOU DO TO GET YOUR LEVELS UP?  I am very worried for my friend and want to be a support to her because she doesn't have any family support..  I had wls 7 months ago and am doing fine.  Please give me any suggestions that I may pass on to her.  I appreciate any help you  can give.
