Asthma is a chronic lung disease that can start at any age. It is considered one of the most common long-term diseases among children. Currently, we do not know how to cure the disease; however, steps can be taken to manage it, including removing environmental triggers that can make asthma worse. There are several factors that can increase your risk of asthma, including hereditary factors. If someone in your family has asthma, it’s more likely you will have it as well.

Asthma is marked by recurring episodes of airway obstruction caused by exposure to “asthma triggers” which results in inflammation of the airways where the muscles surrounding the airways become tight and the lining of the air passages swell. This can lead to labored breathing, wheezing sounds, coughing, and chest tightness. Other symptoms may be present; however, most people with asthma have wheezing attacks separated by symptom-free periods.

Asthma attacks can last minutes to days and can become dangerous if the airflow becomes severely restricted. In sensitive individuals, asthma symptoms can be triggered by breathing in allergy-causing substances. Triggers include pet dander, dust mites, cockroach allergens, molds and pollens. Asthma symptoms can also be triggered by respiratory infections, exercise, cold air, tobacco smoke and other pollutants, stress, food or drug allergies. Aspirin and other non-steroidal anti-inflammatory medications (NSAIDS) can provoke asthma in some patients.
