Tip of The Week- Reactive Airway Disease
Asthma is a disorder caused by inflammation in the airways (called bronchi) that lead to the lungs. This inflammation causes airways to tighten and narrow, which blocks air from flowing freely into the lungs, making it hard to breathe. Symptoms include wheezing, breathlessness, chest tightness, and cough, particularly at night or after exercise/activity.
Asthma usually has many causes or triggers. The triggers that may result to the occurrence of asthma include respiratory infections, allergens, irritants, weather changes, activities, GERD, upper airway inflammation and emotional factors.
A high percentage of children with asthma also has some type of allergy, the allergy isn’t always the primary cause of asthma. Even if allergies are not primary triggers for asthma they can still make symptoms worse.
The goals of asthma therapy are to prevent chronic and troublesome symptoms, to maintain lung function as close to normal as possible, maintenance of normal physical activity levels, to prevent recurrent asthma attacks and to reduce the need for emergency department visits or hospitalizations, and to provide medicines that give the best results with the fewest side effects.
Medications for asthma include inhaled corticosteroids, and long-acting bronchodilators.
