Medicine is simultaneously both easy and hard. As an Infectious Disease doctor, my day can be summed up with the phrase “me find bug, me kill bug, me go home.” Sometimes it is just that simple. A lot of the time it isn’t. I may not be certain what the infection is, or even if the patient has an infection, or allergies and/or antibiotic resistance limit therapeutic options, the host has co-morbidities that limit effectiveness, and the patient has no financial resources for the needed treatment.
I am lucky, since most infections are acute, make people feel terrible, and require a relatively short course of therapy during which the patient feels better. I rarely have to worry about compliance with the treatment plan; it is the rare patient, usually a heroin user or a particularly irascible old man, who will not follow through with their antibiotic course. I do not have to worry about chronic or symptomless diseases like diabetes or hypertension or the complications of obesity where long term compliance often limit therapeutic success. Long term it is difficult for many people to stick with their therapeutic plan, much less their diet and exercise resolutions.
