Various forms of alternative medicine, such as functional medicine and integrative medicine, have been quickly gaining popularity in the 21st century. Both disciplines are highly regarded by world-renowned health care practitioners such as Drs. Deepak Chopra, Mark Hyman and Dean Ornish. Many believe functional and integrative medicine are the future of medicine. Physicians are beginning to take a more holistic approach to treating patients, no longer just concentrating on treating a disease. Although functional medicine and integrative medicine have similarities and overlap in several areas, there are a few factors that make each discipline somewhat unique.
