A functional medicine doctors are medical professionals that focus on systems biology in order to look for common root causes of functional health problems. Consider an old car that has been sitting in your garage for a few years. It might not run because it is out of gas, or the battery is dead or maybe just the tires are flat. By looking at the whole picture you can prioritize what to fix first to get it running again. (Hopefully you didn’t ignore your body for a few years!) Functional medicine doctors or professionals can be holistic chiropractors, integrative medical doctors or other health professionals that have done extensive training in functional medicine.
