On average? No idea. Theoretically the minimum it takes before you're allowed to apply for anaesthetics training positions is 2 years after you graduate, although I gather you'd be doing very well to get on that quickly. My understanding is that, where I am at least, they usually like you to have 3 or 4 years under your belt before you get onto the program.so lets say i do undergrad biomed then move onto post grad med 4 years later, on average how many years will i be looking at to be a anaesthetist?
I'm pretty sure anaesthetics is then a 5-year training program, assuming you do it all full-time, don't take any time off, and pass everything on the first attempt.
The specifics are impossible to predict considering you're yet to even start medical school, but between your undergrad degree (3 years), med school (4 years), your pre-vocational years (~2-4 years) and specialty training (~5 years)... You're looking at at least 15 years.
But seriously, don't worry about that now. There's nothing you can do about it, for starters, and there isn't really any rush, for seconds. Hell, I'm in my 7th year of university, having gotten into medicine as an undergraduate and then spending a couple of years off doing research and other postgraduate stuff. It's not a race.
