Do you know that it was only on October 16, 1846, less than two centuries ago, that an early form of anesthesia was first used? Surgeries, however, have been part of human history for thousands of years.

Today, it’s challenging to imagine even the simplest of procedures being performed without anesthesia. Professionals in charge of it play an immense role in ensuring operations proceed seamlessly, guaranteeing the safety and comfort of patients.

Anesthesiology presents an excellent career option. Yet, as with many medical paths, the time commitment can be a concern. So, how long does it take to become an anesthesiologist? Read on to find out.

What Is an Anesthesiologist?

An anesthesiologist is a medical professional with specialized expertise in administering anesthesia for surgeries and other medical procedures. These professionals play a pivotal role in ensuring the safety and comfort of patients during medical interventions. They are skilled in evaluating a patient’s medical history, determining the most suitable type and amount of anesthesia, and monitoring vital signs throughout the operation.

They often work closely with general surgeons before the surgery, planning and discussing the anesthesia strategy for the patient as well as during and after the procedure to ensure the patient’s safety and comfort.

What Does an Anesthesiologist Do?

Anesthesiologists play a vital and multifaceted role within healthcare, reflected in their range of duties and responsibilities, including:

  • Evaluating their patient’s medical history.
  • Determining the most appropriate type and dosage of anesthesia.
  • Administering the anesthesia.
  • Monitoring vital signs throughout the surgical or medical procedure.
  • Adjusting anesthesia levels as needed to ensure the patient’s comfort and safety.
  • Managing any complications or negative reactions that may arise during anesthesia administration.
  • Collaborating with surgical teams and other healthcare professionals to create a controlled and optimized environment for surgery.
  • Providing preoperative consultations and post-operative care to address anesthesia-related concerns.
  • Utilizing advanced monitoring equipment and technology to ensure precise control over anesthesia delivery.

How Long Does It Take To Become an Anesthesiologist?


Becoming an anesthesiologist is a path that demands dedication, rigorous study, and a substantial investment of time, approximately 11-12 years of structured education and training, spanning undergraduate studies, medical school, and residency.

To better understand the time allocation at each stage of the anesthesiologist’s schooling and training journey, let’s look at a step-by-step guide on how to become an anesthesiologist.

Earn a bachelor’s degree

The first step encompasses around four years and involves earning a bachelor’s degree. Although there isn’t a specific major requirement, many aspiring anesthesiologists opt for a pre-medical track or a science-related field like biology or chemistry. This foundational education lays the groundwork with a strong grasp of biology, chemistry, physics, and mathematics, providing a crucial foundation for understanding human physiology and medicine.

Following the completion of this degree, aspiring anesthesiologists must prepare for and excel in the Medical College Admission Test (MCAT), as its scores are crucial for gaining admission to medical schools, marking the next step in the anesthesiologist’s educational journey.

Complete a four-year medical school program

Another substantial portion of an anesthesiologist’s education is dedicated to medical school, typically spanning another four years. This program provides an in-depth understanding of medical principles and practices through preclinical and clinical sciences, equipping future anesthesiologists with the knowledge and practical skills required for excellence in anesthesiology.

Complete a medical residency program

Post-medical school, anesthesiologists, like many different types of physicians, must undergo a residency program to develop the clinical skills and expertise necessary for independent practice. The length of the residency varies by specialization. For anesthesiology, it encompasses three years of specialized training and an additional PGY-1 Transitional/Preliminary year.

Secure a fellowship

While not obligatory, anesthesiologists can opt for further training through fellowship programs. These programs offer specialized training in pain management, critical care, or pediatric anesthesiology. Typically lasting one to two years, they provide extensive hands-on experience, enabling anesthesiologists to acquire advanced skills and knowledge for specific clinical settings.

Get a license

Before practicing independently, aspiring anesthesiologists must obtain a state medical license. Licensing requirements vary by state but generally involve completing the necessary education and passing the U.S. Medical Licensing Examination (USMLE).

Become board certified

Last but not least, while not obligatory, board certification is strongly recommended for those seeking to demonstrate their knowledge and commitment to excellence in the field. One must pass the American Board of Anesthesiology (ABA) certification exam to attain board certification. The time needed to obtain this certification varies by person and their level of preparation.

Factors That Can Affect the Length of Your Training


Several factors can influence the duration of your training in the pursuit of becoming an anesthesiologist, including your:

  • Educational background: Individuals with a solid foundation in relevant sciences and notable accomplishments may advance more swiftly through specific stages of training, such as examinations.
  • Specialization choice: Some specializations are less competitive than others, ensuring a shorter period needed to secure a place in a specific school or residency program. Moreover, the availability of residency and fellowship program positions and the capacity of training institutions can affect the timing of your training.
  • Residency program structure: The length of the residency program can vary by institution and specialization; thus, it influences the overall duration of your training.
  • Schedules and program formats: Opting for part-time or flexible training schedules, though less common, can prolong the duration of your training.
  • Personal circumstances: Life events, such as medical leave, family obligations, or personal matters, can impact the pace of your progress through your training.
  • Additional fellowships: While optional, pursuing fellowship programs after residency can add one to two years to your training.
  • Research or academic pursuits: Engaging in research projects or pursuing advanced degrees, such as a master’s or PhD, alongside your medical training can extend the timeline.
  • Licensing requirements: Because licensure requirements vary by state, meeting specific ones in your jurisdiction can influence the timeline, especially if additional exams or coursework are necessary.
