Pulmonology is a medical specialty focused on diagnosing and treating conditions related to the lungs and respiratory system. This field addresses various diseases, including asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer. Pulmonologists, the doctors specializing in this area, use various tests and procedures to evaluate lung function and overall respiratory health. Patients may visit a pulmonologist for symptoms like persistent cough, shortness of breath, or chest pain. Treatment options can include medications, inhalers, and lifestyle changes, as well as advanced therapies like bronchoscopy or pulmonary rehabilitation to improve lung function and quality of life.
