That probably depends on how sick you are right now. If you can buy time, it would probably be a good idea to restart the diet and see if it helps you but as you know, it can take time to help. If your doctor is discussing immediate surgery or surgery in the near future, or biologics to prevent surgery, then maybe you don't have the luxury to do the diet instead right now. For example, if someone's colon is so inflamed to the point that when it's removed it actually crumbles, the SCD diet wouldn't have helped restore that colon; it was too messed up and needed to be removed. If your doctor says your case is urgent, then you can go back on SCD while you start a biologic. Good luck!
