Asthma is a chronic respiratory condition marked by inflammation and narrowing of the airways, which causes symptoms like wheezing, coughing, shortness of breath, and chest tightness. It is usually managed with inhaled corticosteroids, bronchodilators, and lifestyle adjustments — not insulin. While both asthma and diabetes are chronic conditions that require daily management, they affect very different systems in the body. Insulin has no impact on lung function or airway inflammation. Confusing the two could lead to misunderstanding treatment strategies or delaying the right interventions. For asthma, focus is on airway control; for diabetes, it’s blood sugar regulation through insulin or other glucose-lowering therapies.
