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:
Allergy tests are a way to get to the bottom of what's causing your asthma symptoms. They help your doctor find your asthma triggers and prevent breathing problems.
But allergy tests alone are not enough to make an asthma diagnosis. Your doctor will look at your history of allergic reactions, too.
Several types of allergy testshelp with asthma, including skin tests and blood tests. The results of your allergy tests may show what's triggering your asthma and allergy symptoms, and that can help...
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.
