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:
Based on your child's history and the severity of asthma, his or her doctor will develop a care plan, called an "asthma action plan." The asthma action plan describes when and how your child should use asthma medications, what to do when asthma gets worse, and when to seek emergency care for your child. Make sure you understand this plan and ask your child's doctor any questions you may have.
Your child's asthma action plan is important to successfully controlling his or her asthma. Keep it handy...
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.
