What is Functional Medicine?

Functional medicine finds and addresses the cause of disease, using the latest cutting-edge evidence-based, and science-based methods. We provide the services of Functional Medicine in Lancaster, PA.

Here is an example of how Functional Medicine works:

Problem: The patient is suffering from fatigue. Thyroid lab tests show low thyroid.

Functional Medicine solution:

Look for reasons why the thyroid is stressed. Perform detailed testing as necessary to determine the cause and explore what diet and lifestyle habits might be contributing to or exacerbating the problem. Provide a comprehensive recommendation that takes the whole person into account. The solution is collaborative. The patient takes an active role in his or her care. All recommendations are safe and natural. The doctor does not consider care a success until the patient actually feels better.

Contrasted with:

Conventional solution:

Provide medicine to bring thyroid numbers back into the normal range. The patient might not feel better, but the lab numbers are now normal, so the doctor considers her to be cured. Most of the time the only solution is medication and there is nothing else the patient can do to get better.

 Functional Medicine at Sheehan Natural Health is Different

We use a unique functional approach by combining Advanced Lab Testing and Nutrition Response Testing to find the root cause of your symptoms. Our comprehensive lab panel is our roadmap to find root causes. Nutrition Response Testing shows exactly what nutrients your body needs while also providing consistant feedback each visit to show how you are progressing. You will not find this kind of care anywhere else.

All of our recommendations are completely natural and safe. We don’t use treatments that could possibly hurt you, such as surgery or drugs. The whole-food supplements that we use do not have side effects. This is the advantage about our therapeutic approach. We have developed this approach based on more than 20 years of clinical experience helping patients get well using safe, natural therapies.

Now that I am 8 months in, all of my symptoms have lessened significantly… Dr. Sheehan is patient and thorough. He answers your questions and adjusts supplements, etc. as needed. -Bloodwork and lab tests support his findings.”
