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:
As winter weather rolls in, so do colds and flu. But for those with asthma, it can be an especially stressful time of year because even a simple cold virus can trigger a major asthma event.
"In asthma, the lungs are already irritable and more reactive. So any virus that impacts the lungs has a propensity for creating more problems, including bringing on an asthma event faster and easier than many people realize," says Jonathan Field, MD, director of the Allergy and Asthma Clinic at NYU Medical Center/Bellevue...
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.
