What is a typical sign of chronic bronchitis?

A typical sign of chronic bronchitis is a chronic cough. This condition is characterized by a persistent cough that produces sputum for at least three months in two consecutive years, which aligns perfectly with the definition of chronic bronchitis. The cough serves as a response to inflammation in the airways, which leads to increased mucus production.

While other symptoms, such as chest tightness and shortness of breath, can occur, they are not as defining of chronic bronchitis as the cough is. Frequent sneezing is more commonly associated with allergic reactions and is not a primary symptom of chronic bronchitis. Identifying a chronic cough is crucial in diagnosing this condition, as it helps differentiate it from other respiratory disorders.
