In order to be a anesthesiologists you have to go to medical school be one. One of the biggest challenges with becoming anesthesiologist is of how rigorous the courses are because anesthetics are dangerous and a doctor could quickly kill someone if they were to mess something up. You will first need to get a bachelors degree, most likely in a STEM released field (biology or chemistry) and then apply to medical school. From there medical school is around 4 plus years and then you will have to begin establishing residency by completing internships until you have accrued enough time to become a anesthesiologist. I think if you were to spend some time looking online a reading more into it, you will be able to answer more of your in depth question.
Hopefully this helps! Good luck!
The diversity in the challenges of patient care really attracted me to the field. If you love what you do, it does not feel like work!
