A 43 y/o male presents with fatiguability, dry mouth, and impotence. Physical exam reveals mild hepatosplenomegaly and atrophic testes. His fasting blood glucose is 252 mg/dL. His urine is positive for glucose but negative for ketones and protein. He also says he developed a "strange tan" despite spending almost all his time indoors. What's wrong with him? How do we know that this is a presentation of hemochromatosis and not high ACTH? I feel like high ACTH would explain for his atrophic testes, his blood glucose, as well as his skin discoloration.
