 [ Symptoms ] can an asthma attack be triggered by traveling from high altitude to a low altitude destination  my 6 year old son traveled with his father from colorado to north carolina for a vacation he has a history of mild asthma with only one previous attack a year ago accompanied by a cold he did not have any symptoms of a cold when he left and no trouble breathing 45 minutes after arriving in north carolina he had a severe asthma attack and was treated by airport paramedics with two albuteral nebulizer treatments could this be caused by going from one climate to another [ Disease ] i am an asthma sufferer living in south africa i migrated from the coastal town of durban which is very humid to johannesburg which is inland and has a dry climate and at a higher altitude my conditions improved to the extent that an inhaler asthavent lasted for more than 3 months i actually had no need for the preventative measure corticosteroids foxair however when i moved to cape town a coastal city i initially needed at least one inhalation in the morning of the 25050 that was 8 years ago about 3 years ago i had development of phlegm in the chest which i attributed to a certain medication pearindaporil i do not have hbp but my cardiologist recommended and prescribed it about nine months ago the phlegm became problematic and i had shortness of breath i have consulted with my gp and a pulmonologist my asthma medication has more than doubled and strengthened montelukast x once daily 50050 of foxair x 2 daily asthavent when necessary and medication for gerd x once daily of course the hbp meds have also changed as the pearindaperil allegedly causes build up of phlegm i have worked on a process of elimination of causes of the condition by severely adjusting foods and drinks as a matter of interest i do hunting fishing and boating brisk walking and sometimes squash i can only put my present condition down to change in altitude and i am considering relocating to a higher altitude again mahomed khan mahomed@maskattorneys co za
