Appetite shot, weight loss, anemia and a high co2

[Pantalones]

Next Thursday I'm making a trip to see my doctor because over the past few months, the symptoms I've been experiencing have gotten worse. I'm hoping he sees enough of a problem to go ahead and do some thorough BW, but based on my symptoms and what I already know, I'm not sure where he'll start actually. Logically I would assume he'd want to get the the bottom of why both my hemaglobin and hematocrit were low, especially since my testosterone levels are good. Potentially test B12, iron, folate etc. As far as the appetite, maybe a liver panel, I don't know what else. The weight loss could be related to the appetite loss, most likely is, but I've been experiencing gastrointestinal problems too. Mainly cramps and excessive gas very uncommon for me usually. I feel like all of this is progressing, and that now would be a good time to get this all sorted out before I'm really screwed. Does anyone have an idea where he'd start looking, or best guesses for what's going on?

I'm currently prescribed 200 mg of cyp a week, but I only do 100 because 200 puts me way over the normal range.

Thanks.
