Pulmonary diseases, also known as lung diseases, are conditions that affect the lungs and respiratory system. Some common pulmonary diseases include:

• Asthma: A chronic inflammatory disease that causes the airways to narrow and swell, leading to wheezing, shortness of breath, and coughing.
• Chronic obstructive pulmonary disease (COPD): A group of lung diseases, including chronic bronchitis and emphysema, that cause airflow blockage and breathing difficulties.
• Pulmonary fibrosis: A condition in which lung tissue becomes thickened and scarred, making it difficult for the lungs to function properly.
