No I had intestinal bypass in 1973. I eat anything I want to eat. The doctor told me green vegetables especially leafy ones would cause gas. I did have to have liver function test every 6 months for a couple of years. The only trouble I ever had was my fault. I got depressed in 1978 or 79 and pretty much stopped eating wound up in hospital with severely depleated potassium. Then a couple of times Ihad potassium drop but last time was 2009.
I did find out the type of surgery does limit my ability to absorb fat soluble vitamins.
Just put the post out here to see if anyone had same surgery and if they had problems
