Pulmonology is a medical specialty focused on the respiratory system. This medical field falls within internal medicine. Pulmonologists, or those who study pulmonology, first complete an internal medicine residency before spending several years in a pulmonology fellowship.
Some further areas of specialization in pulmonology include certain diseases, such as pulmonary fibrosis, asthma, and COPD. Other pulmonologists may specialize in the treatment of specific populations, including pediatrics or geriatrics.
Pulmonology is often closely related to cardiology since many heart and lung conditions have similar symptoms. Because of this, pulmonologists often work closely with cardiologists when diagnosing patients.
