You ascended to high altitude and shortly thereafter exhibited a throbbing diffuse headache, polyuria, and nausea. Textbook. In the absence of a significant previous medical history, you won't find a doctor who tells you otherwise. I'm not saying dehydration couldn't have played a role, but your medical diagnosis was AMS.
I don't care if you were cold, or have a small bladder, or were dehydrated (well, I do, I don't want you to have to worry about any of that). Even if that's all true, you still had AMS. Keep training at altitude and with any luck you won't get it again!
Actually, with AMS urine output decreases.
Urine output is increased as part of acclimatization as well as in mild AMS. It decreases in moderate to severe AMS (Auerbach, 6th Ed. of "Wilderness Medicine." This book is my bible).
