Gluten Intolerance and Vitamins

I am pre-op and currently am gluten intolerant and have issues taking vitamins where it feels like someone punched me in the stomach and then inflated by stomach.  

Does the gluten issue continue post-op?  If vitamins are hard on you stomach now - does it get better post op?

for me - I developed gluten intolerance post op. It got worse. 

vitamins - for long time I only could take chewable. Centrum or equivalent. 

big multi pills are still no go...but now i can swallow Centrum equivalent - CVS brand multi. Most of the time. 

BTW:I am 7 years post op RNY

thank you
