Why wouldn't it be T3? Thyroid hormones also ↑blood sugar and break down lipids
@ankirin his symptoms aren't really specific for T3. They don't mention tremors, exopthalmos etc. I think just in physiologic terms, you can bet cortisol is more increased. It's not a great question though imo
can someone comment on why his appetite is down, per first aid 2019, page 329, cortisol increases appetite. thank you
Can anyone take a little time to curse on that daughter?
Sure, charcot. Just wished on her to get a couple of charcots (the triad, your aneuryms, marie tooth, etc).

Honestly, it's something that has confused me for a while. Why is it that GH secretion is stimulated by hypoglycemia? I mean, it's literally called growth hormone (for growth!), and hypoglycemia, which is basically a "starvation" state, will stimulate this hormone?
IGF-1 is regulated by insulin. so it will be decreased because insulin levels are also low.
thank you @shaeking!
I found this and it also explains to a more genetic/cellular level. Essentially, it says that starvation induces some factors that cause GH resistance and IGF1 suppression.
according to pathoma, cortisol is the hormone neccessary for life. in a condition like the one presented in the Q-stem the most important hormone will be cortisol.
Also Cortisol is generally a stress hormone. Starved body is generally understress--Cortisol
