Functional healthcare views symptoms as the body's way of letting us know that something is amiss. In the functional model, symptoms are purposeful indicators, and not random occurrences. Functional medicine attempts to remove stressors that cause the body to signal that something is wrong, and also offers support to weak areas. Functional medicine views signs and symptoms as important messengers that will lessen and disappear when their cause is alleviated.
Although self-managed programs like juice fasts can certainly be useful, they only address one side of the equation by providing a simple way to reduce our intake of toxins. Although this is beneficial, detoxification can be more effective by simultaneously addressing the other side of the equation: fueling the liver (and other detoxification organ functions) to eliminate more toxins than under normal circumstances.
