how does higher altitude affect urnation? . i am going to tahoe and yosemite to around 6 000 to 8000 feet. i am 66 and have slowed urination and sometimes have problems on international flights at altitude in a pressurized cabin. i normally live in dallas. .
altitude should not effect your ability to urinate. you may have an enlarged prostate (common at age 66) and difficulty urinating is common. at any altitude.
