  • Form of bronchial disorder associated with airway obstruction, marked by recurrent attacks of paroxysmal dyspnea, with wheezing due to spasmodic contraction of the bronchi6-8
  • Chronic respiratory disease manifested as difficulty breathing due to the narrowing of bronchial passageways
  • Chronic lung disease that inflames and narrows the airways leading to recurrent periods of wheezing, chest tightness, shortness of breath, and cough
  • Coughing often occurs at night or early in the morning, but may go unnoticed during the day or be considered an allergic response to an inhaled (airborne or environmental) trigger
  • Affects people of all ages, but most often starts during childhood
  • More than 22 million people are known to have asthma in the United States; nearly 6 million are children6
  • People with asthma have inflamed airways, which may become sensitive and tend to react strongly to certain inhaled substances
  • When airways react, the muscles around them tighten, narrowing the lumen wall leading to less air-flow into the lungs; swelling of the lumen may result in narrowing, leading to further restriction and triggering a cascade of cells to thicken mucus or increase mucus production
  • Symptoms may be mild and self-resolve or require minimal treatment with prescription medication; some symptoms are persistent and require ongoing prescription medication for control
  • Symptom recognition is important, to prevent long term damage
  • Children often have difficulties expressing symptoms of an attack, so adults must be aware of a child’s presentation so treatment can be initiated to prevent a severe attack, which may require emergency care or be fatal
  • Comorbidities may exacerbate the symptoms or make management more ...
