An anesthesiologist is a medical doctor who keeps you safe and comfortable before, during, and after surgery by managing anesthesia, pain, and vital functions like breathing, blood pressure, and heart rate.

Quick Scoop

They do much more than “put you to sleep.” An anesthesiologist checks your health before a procedure, chooses the safest anesthesia plan, monitors you throughout surgery, and helps manage pain and recovery afterward.

What they do

  • Before surgery: Review your medical history, medications, allergies, and test results; decide what type of anesthesia is safest.
  • During surgery: Give anesthesia, watch your vital signs, adjust medicines, and respond quickly to any problems or emergencies.
  • After surgery: Help you wake up safely, monitor for complications, and plan pain control for recovery.

Why they matter

Anesthesiologists help protect your body while you are unconscious or less aware of pain, which is especially important if you have conditions like asthma, diabetes, or heart disease. They work closely with the surgical team to keep the procedure as safe as possible.

Common specialties

Some anesthesiologists also work in pain medicine, intensive care, obstetric anesthesia, or cardiac anesthesia, depending on their training and interests.
