My son has been experiencing hypothyroid/sluggish adrenal symptoms (based on what I have read) for a year or two. 1 endo suggested hypo, but test results came back OK. Another 1 also said the same thing, based on what the first one said. My wife has been told that the blood test is the last result, that a saliva test would be more indicative of a problem. His symptoms are the following: Extremely sluggish or lethargic, gets upset/stressed very easily, very slightly chubby face and stomach, tired or droopy looking eyes, very little lean muscle, slightly short stature(25th percentile), slightly slow growth (<2.5"/yr). He is extremely active in 2 sports. We thought he may be burned out, but even when he has nothing going on, he is still always tired. I have heard all kinds of advice from Armour thyroid, growth hormone therapy, sluggish or burned out adrenals. He did have a very slight concussion playing hockey in Jan of '08. We, along with other parents, really noticed the symptoms after that, especially in the late spring and early summer. We are going to take him to 1 more pediatric endo, and after that, I don't know what we will do. Does anybody have any experience with this? My son seems to slowly be getting worse.
