If where you live can negatively effect your health, then why don't doctors take that into account during checkups?

In class we learned that depending on where you live can really negatively affect your health. In the video we saw that the individual lived in multiple places in the world all with terrible environmental health issues that caused him to have a heart attack. He pondered as too why you fill doctors don't recommend and take into account where you live when asking the billion questions they already ask you. As I looked online I truly couldn't find any valid research to answer my question. But going off the video we watched and my own personal opinion I think it is due to the fact that there is not many places in there world today that the environment is truly pure and clean. Doctors wouldn't be able to make many recommendations as to how to fix the problem besides saying move to a more environmental healthy place which isn't a realistic option for most people. Yet, I do believe that doctors should take that into account when diagnosing why someone has a specific health problem.
