Hey there, My name is Andy and I'm new here. I am going on 20, and was diagnosed at just before turning 18. From what my first doc had told me, crohns itself for some reason causes fatigue to the body. I'm sure all the different meds people are on probably only increase the fatigue because if you think about it, they are all immune suppressors of some sort, and when you're sick because of a low immune system, you're generally more tired right? Sort of just makes me think it is probably related even if they don't list fatigue as a side effect on any of the labels. Prednisone actually helped me originally with the fatigue, gave me such a boost being on the higher doses. Though after 2 years on it, it has started losing its effect all across the board from hunger to energy and even its calming effects on the crohns. I just wish there were quicker discoveries into why all these things are effected, to find better ways to overcome them.
