Asthma

Causes and Triggers of Asthma

02/27/2002

Question:

Can pneumonia cause asthma? Also, can being out in cold weather cause asthma or just trigger it? Thank you

Answer:

Asthma can be caused or triggered by viral infections which is often misdiagnosed as `pneumonia` or `bronchitis`. Asthma can be triggered by a multitude of allergic and non-allergic triggers. Non-allergic triggers include exercise, cold weather, viruses, irritants (ie. Smoke, perfumes), certain medicine such as beta-blockers or ACE-inhibitors and so forth. There is no evidence that cold weather can cause asthma but it is a major trigger for many sufferers.
