  "definition": "1. A disease that affects a person's lungs and can make it difficult to breathe. Many factors can trigger an asthma attack. For some people, these triggers may include air pollution, allergens, heavy exercise, or certain weather conditions.\n\n2. A physical condition that makes breathing difficult. People that have asthma usually experience a lot of wheezing and coughing, and often have difficulty doing physical exercise. Asthma is a condition that people usually have for their entire lives.\n\n3. A condition marked by recurrent attacks of difficult or labored breathing and wheezing resulting from spasmodic contraction and hypersecretion of the bronchi. It is caused by exposure to allergens such as drugs, foods, environmental pollutants, or intrinsic factors. See www.epa.gov/asthma\n\n4. A chronic disease in which the bronchial airways in the lungs become narrowed and swollen, making it difficult to breathe. Symptoms include wheezing, coughing, tightness in the chest, shortness of breath, and rapid breathing. An attack may be brought on by pet hair, dust, smoke, pollen, mold, exercise, cold air, or stress.\n\n5. A chronic medical condition where the bronchial tubes (in the lungs) become easily irritated. This leads to constriction of the airways resulting in wheezing, coughing, difficulty breathing and production of thick mucus. The cause of asthma is not yet known but environmental triggers, drugs, food allergies, exercise, infection and stress have all been implicated.\n\n6. A chronic inflammatory disorder of the lungs. Symptoms include wheezing, breathlessness, chest tightening, and cough.\n\n7. Condition marked by recurrent attacks of difficult or labored breathing and wheezing resulting from spasmodic contraction and hypersecretion of the bronchi. It is caused by exposure to allergens such as drugs, foods, environmental pollutants, or intrinsic factors.\n\n8. Chronic disorder of the airways that is complex and characterized by variable and recurring symptoms, airflow obstruction, bronchial hyperresponsiveness (bronchospasm), and an underlying inflammation. Asthma symptoms may be induced by a sensitizer (allergen) or an irritant.\n\n9. Asthma prevalence among adults aged 18 or older. This data is available at the tract level; the same tract value is then assigned to all sub block groups.",
