Asthma is a major noncommunicable disease (NCD), affecting both children and adults, and is the most common chronic disease among children. Inflammation and narrowing of the small airways in the lungs cause asthma symptoms, which can be any combination of cough, wheeze, shortness of breath and chest tightness. Allergies occur when your immune system reacts to a foreign substance — such as pollen, bee venom or pet dander — or a food that doesn’t cause a reaction in most people. The most common asthma triggers include allergies, air pollution and other airborne irritants, other health conditions including respiratory infections, exercise or physical activity, weather and air temperature, strong emotions, and some medicines.
