Pick your passion and go for it.
Don’t go by physiology as the defining aspect of anesthesiology as a discipline - of course it is, but that’s not all. The biggest stressors for most anesthesiologists is not the clinical aspect of care - it’s early hours and being present and under pressure at work, working with unreasonable surgeons at times, calls, labor, work schedule and how to balance their work and life. Basically you are a booty call specialty masqueraded as a ‘service based profession’.
You’ll meet workaholics and really lazy ones, and majority of the crowd in between…ofcourse you won’t be exposed to that as a medical student.
I don’t think any specialty is inferior or superior.
In fact as I progress in my career, I have begun to really appreciate hard working family medicine doctors who know their patients over years and develop good doctor patent relationships and manage them well - often times, surgery is prevented because of their effective management (esp. bariatric s, vascular, cardiac etc).
Even if you choose anesthesiology, don’t forget the “whole patient” approach to the patient.
Anesthesia has physiology but it’s a lot of same and common issues intra op which can be anticipated and managed and it becomes second nature over time.
But yes, it’s a very decent speciality with very rich history and impact on human health - so despite the political climate and reimbursement challenges, you’ll enjoy it.
Good luck.
