What Is Functional Medicine?
Functional medicine is a patient-centered approach that focuses on identifying and addressing the root causes of disease. Unlike conventional medicine, which often just treats symptoms, functional medicine aims to find and resolve the underlying dysfunction in the body that is causing illness.
- Identifies root causes of health issues: Uses a holistic view of body, mind, and spirit
- Functional assessments: Identifies unique biochemical imbalances
- Advanced testing: Reveals true sources of health problems
- Customized treatment plans: Creates natural, holistic plans to restore wellness
- Supports innate healing: Focuses on the body's natural ability to heal


Who Can Benefit from Functional Medicine?
Functional medicine can help transform health for those struggling with:
- Chronic Conditions: fatigue, pain, inflammation, autoimmune disorders
- Hormonal Imbalances: thyroid disorders, adrenal dysfunction
- Weight Problems: obesity, difficulty losing weight
- Mental Health: anxiety, depression, brain fog
