Pulmonology is a medical specialty that focuses on the diagnosis and treatment of diseases and disorders affecting the respiratory system, including the lungs, airways, and chest. Pulmonologists manage conditions such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, tuberculosis, lung infections, and lung cancer. They also care for patients with sleep-related breathing disorders and those requiring mechanical ventilation. Using diagnostic tools like chest X-rays, CT scans, pulmonary function tests, and bronchoscopy, pulmonologists assess lung function and provide targeted treatments to improve breathing and overall respiratory health. Pulmonology plays a vital role in managing both acute and chronic lung diseases, helping patients maintain better lung function and quality of life.
