Asthma is a chronic inflammatory disease of the airways that affects people of all ages. It is one of the most common chronic diseases worldwide, affecting 25 million people in the United States alone. Asthma is characterized by recurrent episodes of wheezing, breathlessness, chest tightness, and coughing.
The three most common triggers for asthma are allergens, irritants, and exercise.
Allergens are substances that can cause an allergic reaction. Common allergens include pollen, pet dander, dust mites, mold, and cockroaches. These allergens can trigger an asthma attack when inhaled.
Irritants are substances in the environment that can irritate the airways and cause symptoms of asthma. Common irritants include smoke, chemical fumes, strong odors, and air pollution.
Exercise is a common trigger for asthma. Exercise-induced asthma occurs when a person’s airways become narrow during exercise. This can cause symptoms such as coughing, wheezing, and chest tightness.
It is important to identify and avoid triggers to reduce the frequency and severity of asthma attacks. For people with allergies, avoiding allergens and taking medications to control allergic reactions can help reduce asthma symptoms. People should also avoid irritants and wear a mask when necessary to reduce exposure. Finally, people with exercise-induced asthma should warm up before exercising and use medications to manage their symptoms.
