Functional medicine is a patient-centered approach to manage chronic disease. Functional medicine is a form of alternative medicine that focuses on identifying and addressing the root cause of illnesses. Functional medical doctors are trained to prevent and manage complex chronic medical problems in a more holistic manner. Functional medical doctors spend time listening to you and gathering information to discover what may be triggering your illness. Examples of lifestyles that can cause chronic disease include poor nutrition, stress, toxins, lack of appropriate exercises, allergens, genetics, food sensitivity or gut problems. Many aspects of your life will be addressed, from physical needs, exercise, sleep, mental and emotional stressors.
