What is the most common chronic childhood illness?

Asthma is recognized as the most common chronic childhood illness due to its prevalence among children worldwide. It affects the respiratory system, leading to difficulty in breathing, wheezing, coughing, and chest tightness, particularly during physical activity or exposure to triggers such as allergens and pollutants.

In school-age children, asthma has a significant impact on daily activities and contributes to school absenteeism. The condition often requires ongoing management, including medications to control symptoms and strategies to avoid triggers, further emphasizing its status as a chronic disease.

While diabetes, allergies, and obesity are also significant health concerns in children, they do not match the widespread occurrence of asthma. Asthma's substantial incidence rates and the necessity for long-term care solidify its position as the most common chronic illness affecting children today.
