Great question. A lot of that depends on what speciality a doctor is in. Some doctors only see patients in an office and have appointments somewhere in the hours of 8 or 9 AM until 5 or 6 PM. Some doctors do procedures and surgeries most of the day, and also spend a few hours in the office seeing patients in follow up or for pre-procedure appointments. The great thing about the medical field is there are many options. You can work in a hospital, outpatient office, or at an academic institution and teach students and residents. Some doctors also work for pharmaceutical or health companies and spend less time seeing patients. I would suggest shadowing doctors in different fields and settings to see what you like best.
