WLS VS NO Additional Vitamins

Hi Everyone

I am writing on behalf of my friend---Seriously!  She had WLS back in 2007 and since then takes no additional vitamins or calcium supplements.  I keep telling her she needs to take her supplements for the rest of her life.  Since my WLS in 2004 I can count on 10 fingers how many times I missed mine!  I take my supplements religiously! 

Can someone please list for me the reaction the body takes without taking any of our required supplements?  I am very concerned for her especially since she is my best friend!  I did notice that she has a big nasty bruise on her leg and she has no idea how she got it...I told her that it is due to a vitamin deficiency....I don't know if she believes me or not but she scheduled an appointment with the OBGYN to have a vein test,

I want to be able to print out on paper what the outcome could be for her down the road if she does not get back on the wagon where her vitamins are concerned!

Thanks
