i have a 9 year old son, who has been overweight since two months of age. he had trouble eating as an infant, colic, jaundice and hypospadia. then he started overeating all the time and having projectile vomiting. he was obese by the time he was 1. we have never been able to get his weight under control, despite close watch on his diet and daily exercise. in the meantime, he still has retractable testicles, low hormone levels (esp testosterone). his doctor found a thyroid nodule on his last year which was 1mm. it is now 2mm with a possible abnormality in the parathyroid. he also has an ast of 71, alk phosphatase of 471, and alt of 207 and an enlarged spleen. no one here can figure out what is going on with him. he is being referred to a specialist out of state in a few days. any idea what i should expect or what other tests i may ask to have done on him? any insight at all? any guidance would be appreciated!
