Asthma is diagnosed with a history, physical exam, laboratory findings, and pulmonary function studies. The strongest risk factor for developing asthma is a genetic predisposition to immunoglobulin E-mediated response to common allergens. Damage to bronchial epithelium and airway inflammation contributes to the pathogenesis. T2 helper cells respond to allergens by stimulating B cells to differentiate into immunoglobulin E producing plasma cells. T2 helper cells also stimulate growth factors for mast cells and activate eosinophils. Cytokines have a big role in chronic inflammation and the associated complications. Tumor necrosis factor alpha, an inflammatory cytokine stored and released from mast cells, increases movement and stimulation of inflammatory cells leading to airway remodeling and mucous cell hyperplasia. The stimulation of neutrophils, eosinophils, lymphocytes, and mast cells cause epithelium injury increasing airway inflammation and decreasing airflow. The inflammatory process causes airway obstruction leading to wheezing, breathlessness, chest tightness, and cough (Grossman,
