Functional Medicine Provider or Naturopath: Who Should You See?

Deciding which professional to see depends largely on your specific health concerns and goals:

  • Choose a Dietitian if you need specialized dietary management to tackle medical conditions like obesity, diabetes, heart diseases, or eating disorders. They often work in tandem with your general practitioner and may be affiliated with local hospitals.
  • Opt for a Functional Medicine Nutritionist if you are dealing with chronic systemic issues such as digestive disorders, autoimmune diseases, or hormonal imbalances, and you’re looking for a detailed exploration of how your diet and lifestyle affect your health. These practitioners are especially helpful when you’ve sought traditional means with little to no progress. They are also great compliments to your general practitioner and seek to heal at the root and not just address symptoms alone. Schedule a free discovery call with me here!
  • Consult a D.O. if you prefer a licensed physician who can provide comprehensive medical care with an additional holistic approach, especially if you appreciate the value of osteopathic manipulative treatments. 
  • You could see a Naturopath if you are interested in exploring natural and alternative therapies and live in a state where naturopathy is well-regulated. Check credentials!
  • Work with a Health Coach if you’re generally healthy but looking to improve your overall well-being, need support in making lifestyle changes, or seek motivation to maintain healthy habits. Health coaches are particularly useful when you know what goals you want to achieve but find it hard to stick to them. They are often personal trainers or life coaches as well.
  • Consult a Nutritionist if you’re looking for specific dietary advice or need help with nutritional plans that might not require medical intervention. Ensure that the nutritionist has credible training, especially if you have specific dietary needs or health conditions that require expert advice. 

Your choice among these professionals should align with your health philosophy and the type of approach you believe will be most effective for your needs. Always check a practitioner’s credentials, ask about their experience with your specific health concerns, take them up on their free discovery calls to ask all of your questions and consider how comfortable you feel with their approach to care. Making an informed choice will help you embark on a path toward better health and well-being.
