There is a medical term altitude-induced diuresis which describes the fact that during the initial phases of altitude acclimatization people urinate more.

According to an article, this happens because of the following. Lower level of oxygen is sensed by kidneys which release erythropoetin hormone that is behind increased production of red blood cells. This happens as a natural reaction of our body. It increases the oxygen-carrying capacity of the blood.

With increased red cells, our body tends to dump extra fluid, and this results in excess urine. The process eventually reduces as we become acclimatized.
