A functional health office visit for an established patient is a follow-up visit to a chronic or new condition with a doctor specializing in functional medicine. Functional medicine is a systems biology based approach that focuses on identifying and addressing the root cause of disease. Each symptom or differential diagnosis may be one of many contributing to an individual’s illness. Functional medicine can be helpful in addressing gastrointestinal, hormonal, sleep, or skin issues, and support optimal health. An established patient office visit is needed if you have seen this doctor before in the last 3 years, otherwise please purchase an office visit for "new patient".
