Pulmonology is a medical specialty that focuses on the diagnosis and treatment of diseases related to the lungs and respiratory system. Pulmonologists, the doctors who specialize in this field, help patients with conditions such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. They use various tests and procedures to assess lung function and determine the best course of treatment. In addition to treating illnesses, pulmonologists also play a crucial role in managing sleep disorders like sleep apnea, which can affect breathing during sleep. They often work closely with other healthcare professionals to provide comprehensive care for patients, ensuring that their respiratory health is maintained and improved over time.
