Spinach is good. Read it
hereWhat other meds besides Mesalazine have you tried? There is so many more maintenance drugs out there. Just because Mesalazine stopped working doesn't mean the end. It seems to happen to a lot of people that it stops working. It did for me. Not sure if this is some kind of immunity?
Have you tried Imuran, 6mp, Remicade or Humira?
I hope you get into remission soon.
