Yes, doing MBBS and being a doctor is excessively stressful. Medicine, as a course, is related to heavy academic pressure, long hours of studies, and difficult exams in general. This continues further in the form of long and irregular working hours, high responsibility, and the emotional burden that comes with the care of patients once they become doctors. At times, staying updated about medical advancements and managing life-and-death situations may be stressful also.
