Frequently Asked Questions
How do I learn more or get started?
Simply fill out a form on our website. Our team will give you a call as soon as possible to answer any questions you have.
Isn’t Functional Medicine expensive?
It might seem costly upfront, but think of it as an investment. Functional medicine addresses the root causes of your health issues, leading to long-term wellness and potentially saving you from the recurring costs of conventional treatments that only manage symptoms. Personalized care tailored to your unique needs can prevent future health problems and associated expenses. It’s about investing in your future well-being.
Do you accept my insurance?
We don’t accept insurance. Insurance companies often don’t cover the in-depth testing we use, and in-network clinics usually have high patient volumes, which limits your time with your physician. At Healing Naturally, we provide thorough, personalized care so you fully understand your health and the steps we’re taking to address it. By not accepting insurance, we can offer you the highest quality care.
What conditions can Functional Medicine treat?
Functional medicine can address a wide range of chronic conditions, including autoimmune diseases, digestive disorders, hormonal imbalances, chronic fatigue, mental health issues, cardiovascular diseases, women’s health and more. Check out the what we treat section of the website for more information.
What can I expect during my first visit?
Your first visit includes a thorough evaluation of your health history, lifestyle, and current health concerns. We discuss your goals, order necessary diagnostic tests, and start developing a personalized treatment plan. Expect this visit to be about an hour long as we take the time to understand your unique health needs.
How do I pay for services?
We accept various forms of payment, including credit/debit cards, HSA/FSA accounts, and offer payment plans.
What does treatment look like?
Our treatments are highly personalized and may include dietary changes, nutritional supplements, lifestyle modifications, stress management techniques, detoxification programs, and, when necessary, traditional medical treatments. All these treatments are based on your story and lab tests.
How long will it take to see results?
The timeline for seeing results varies. Some patients notice improvements within a few weeks, while others with more complex conditions may take several months. Our goal is sustainable, long-term health improvements.
How often will I need to visit the clinic?
The frequency of visits depends on your personalized treatment plan. Initially, you may need more frequent visits to monitor progress and make necessary adjustments. Over time, as your health stabilizes, the frequency may decrease.
