chronic cough

A chronic cough is a cough that lasts for eight weeks or more in adults, or four weeks in children. It can be caused by various factors, including asthma, allergies, infections, or irritants like smoke and pollution. Unlike an acute cough, which is usually temporary and linked to colds or flu, a chronic cough may indicate an underlying health issue that requires attention. Symptoms can include a dry or productive cough, and associated signs may involve wheezing, shortness of breath, or chest pain. Consulting a healthcare professional is important for accurate diagnosis and treatment.
