Smoking-related lung diseases

Smoking-related lung diseases include conditions caused by inhaling tobacco smoke, which damages lung tissue and narrows airways. Common diseases are chronic bronchitis, characterized by persistent cough and mucus; emphysema, where air sacs are destroyed, making breathing difficult; and lung cancer, a malignant tumor often linked to smoking. These diseases reduce lung function, leading to shortness of breath, coughing, and decreased quality of life. Smoking accelerates lung damage over time, and quitting can slow progression and improve health outcomes. Avoiding or quitting smoking is the most effective way to prevent these serious respiratory conditions.
