Just out of curiosity, what pituitary disorder were you diagnosed with? I had a cortisol stimulation test done and the results indicate Secondary Adrenal Insufficiency, which I have an appointment with an endocrinologist to address. Have you had your cortisol level checked during these episodes? The reason I ask is because you say you have a pituitary problem, and I've been doing so much research on Secondary Adrenal Insufficiency, and have found a lot if info on Primary Adrenal Insufficiency (Addison's disease) which is actually an Adrenal gland problem instead of pituitary, but the two disorders are sometimes confused... and your 'episodes' sound a lot like what they call an 'Addisonian Crisis,' which is very dangerous and can be life-threatening when it happens. Apparently, it can happen in both Primary and Secondary Adrenal Insufficiency, so if your pituitary gland isn't producing enough ACTH, it can be causing your cortisol level to drop dramatically, causing the 'crisis.'
Symptoms of an Addisonian Crisis:
Extreme drowsiness, in advanced cases slipping towards a coma
Nausea and/or vomiting
Abnormal heart rate – either too fast or too slow
Abnormally low blood pressure
Feeling extremely cold
Possibly a fever
Possibly abdominal tenderness
Both Primary and Secondary Adrenal Insufficiency can cause a positive ANA test result.
And, they both also cause sodium loss and resulting dehydration, which applies to me. I'm also hypoglycemic, anemic, have had hypothyroidism (although this problem seems to be fine now, even though I'm not taking anything for it), I have low blood pressure (I assume you might have this if you're being referred to a neurologist), orthostatic hypotension, weight loss (I'm skinny!), and my DHEA is high while my progesterone level is low. All of these can be caused by this disorder.
I hope this helps, although you might have already been diagnosed with Secondary Adrenal Insufficiency if you were told you had a pituitary disorder.
