An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around your airways (bronchospasm). During the asthma attack, the lining of the airways also becomes swollen or inflamed and thicker mucus -- more than normal -- is produced. All of these factors -- bronchospasm, inflammation, and mucus production -- cause symptoms of an asthma attack such as difficulty breathing, wheezing, coughing, shortness of breath, and difficulty performing normal daily activities. Other symptoms of an asthma attack may include:
If you were recently diagnosed with asthma, ask your doctor these questions at your next visit.
1. What is asthma?
2. What are the causes of asthma?
3. Are there things I can change in my life to reduce my risk of an asthma attack?
4. What kinds of tests will I need to monitor my asthma?
5. How do I use an asthma inhaler?
6. Are there some alternative therapies I can use along with my asthma medications?
7. Is it safe to exercise with asthma?
8. Why do I need an asthma action plan?
Some people with asthma may go for extended periods without having an asthma attack or other symptoms, interrupted by periodic worsening of their symptoms, due to exposure to asthma triggers or perhaps from overdoing it as in exercise-induced asthma.
Mild asthma attacks are generally more common. Usually, the airways open up within a few minutes to a few hours after treatment. Severe asthma attacks are less common but last longer and require immediate medical help. It is important to recognize and treat even mild symptoms of an asthma attack to help you prevent severe episodes and keep asthma under control.
