Extreme fatigue after one year of gastric bypass surgery?

I've had the surgery almost 2 yrs ago. I've been experincing fatigue myself, but that could be from the fact that NOW i have a low thyroid fuction.. so you want to talk to your doctor or surgeon about getting blood work done, it could be low iron or anything i hear also the B-12 shots help a lot too, cause after the surgery our ability to absorb B-12 is different. most deffenetly get blood work done, and follow up.

i am so tired 3 years after surgery i feel like just walking is to hard. i need direction as to how to cure this. any suggestions?
