I believe the body is a very well integrated system and all the parts works in conjunction to not just keep you alive but also make sure you live a very vibrant life, full energy and vitality. Having a general practice gives me the opportunity to work with the most variable type of ailments and patients.
The principles I use are: to gather enough information about the patient complaints, order some labs if necessary, analyze all the variables to come up with a diagnosis; implement actions to address the problems and follow up with the patient to adjust or change the actions, in case the results are not as expected.
