Remission, weight gain, training

Hi guys,

I've been in remission now for around about a year with only the odd gargle and loose stool here and there but here is my dilemma. Ive been training for a long time but always been a skinny guy at 6ft and I've been trying to stack on the pounds for a long time moving from 2500cals slowly up to my current of 4500xals but I can't seem to gain weight.

Would My colitis be causing me problems in absorbing food to allow me to grow or in some.other way affecting things?

If so is there anything else I can do to help/sort this?

It has me really stressed out I'm trying all kinds and eating enough for a guy twice my size but still no gain. I have booked in for blood tests to have my thyroid checked just in case but I cannot thing of any other conditions that could be causing problems

Thanks guys I really appreciate any help or advice.

Sounds like it is another problem.

I'm just getting better within the past month after being sick to various degrees for the last year and a half. During that time I continued to lift but was never getting bigger or gaining weight. I would always hit the same plateaus, become too sick to do much, then lower the weight by a lot and work back up. It was a constant up and down battle but I continued to workout whenever possible to try to maintain some sort of strength/physical fitness.

Since I've been feeling better the past month, I have started to gain weight and can tell I'm getting bigger and stronger. I'm getting very close to those plateaus that I would always hit a wall at and feel like I will have no problem blowing right past them now that I'm better.
