How to tell if these are acromegaly symptoms?

Check IGF-1: Hi. If we suspect acromegaly on clinical grounds, we check an IGF-1 (and I also get an IGFBP-3); I get a GH, but it's seldom helpful at the screening stage). If IGF-1 is elevated, then a growth hormone suppression test is done. If that's abnormal, we then do a pituitary MRI. Acromegaly tumors are usually big and easy to see. Good luck!
