How does altitude affect the kidneys?

At altitude, a very common reaction is increased urinary output. The body’s kidneys sense the lower level of oxygen immediately and kick into high gear. The kidneys release a hormone, erythropoetin, that commands the bone marrow to produce more red blood cells to increase the oxygen-carrying capacity of the blood.
