Description

++

  • Form of bronchial disorder associated with airway obstruction, marked by recurrent attacks of paroxysmal dyspnea, with wheezing due to spasmodic contraction of the bronchi.5,6,7

  • 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 children.6

  • 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 airflow 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 ...
