Doc told me that it was a pretty easy call, he just had to connect the dots really.
It first crossed his mind when I came in for my appointment with a 4L jug of water(which I had to carry around with me all the time at that point). I was drinking 6-8 litres of water a day out of necessity and having to piss about every 15 minutes. He ordered BW and confirmed that my electrolytes were significantly out of whack, on top of the low test. He prescribed a desmopressin nasal spray(synthetic vasopressin, which is an anti-diuretic hormone secreted by the pituitary) and the problem vanished. With that he took into account the fact that all my symptoms had appeared after my last concussion(in may 2010). He told me that when diabetes insipidus and symptoms of secondary hypogonadism appear virtually simultaneously after traumatic brain injury it's pretty much a slam dunk.
Forgot to mention, he ordered an MRI to screen for a pituitary adenoma just incase, but it came back clear.
