Warning Signs of an Impending Asthma Attack
There are warning signs that signal an impending asthma attack. By learning to recognize these early symptoms as warning signs, you can help prevent attacks or reduce their severity.
What Happens During an Asthma Attack?
Exposure to asthma triggers can cause airways to contract and become inflamed, narrowed, and clogged with mucus. Less room is available for air to flow in and out of the lungs. The duration of the asthma attack varies. Attacks range from mild to severe and last anywhere from a few minutes to several days. During attacks, bronchial muscles go into spasm, causing air to be trapped in tiny air breathing sacs in the lungs, called alveoli. Asthma attacks may be fatal if not identified and treated.
