Anesthesiologists are medical doctors who specialize in
anesthesiology, which is the medical science of relieving pain
and managing the body's vital functions, such as breathing, heartbeat, circulation, temperature, and consciousness.
An anesthesiologist may administer medicine that numbs the area
of the body where a procedure is being performed (regional

medicine, pain management, pediatric anesthesia, cardiac anesthesia, or obstetric anesthesia.
Anesthesiologists can be board-certified through the Board of
Anesthesiology, which is recognized by the American Board of Medical
