[pct-l] Asthma at altitude

[Ellen Shopes]

The lower oxygen levels in the lungs triggers vasoconstriction.  This
constriction can result in pulmonary hypertension and pulmonary edema.  In
this setting, some bronchoconstriction could occur.
Most likely you will adapt without problems.  I'm sure you plan to bring an
inhaler.  You may want to discuss it with your pulmonologist, see if he/she
would want to add a rescue inhaler.
Diamox wouldn't help with this.  You may try sleeping with a bit of a prop
to elevate your head, particularly if cold is a trigger for you.
