Functional medicine might be considered by some to be a “new” approach to treating conditions and diseases. In reality, it’s probably the oldest approach in the world. Hippocrates has been credited with saying, “The greatest medicine of all is teaching people how not to need it.”
Traditional medicine excels at delivering life-saving measures for acute medical problems. But when it comes to treating chronic disease, the current “pill for every ill” healthcare model is failing. Chronic disease is on the rise, and life expectancy is falling.
Functional medicine offers a scientific, researched-based approach to combat chronic disease by restoring health.
Have you ever felt like you don’t have enough time with your doctor to really talk about your health?
Our functional medicine appointments are longer. We take the time to listen and ask questions to get a complete picture of your health. The end goal is to correct what is not functioning properly within your body to restore your health.
Beware of clinics with a shelf full of packaged solutions for a range of conditions. As a Diplomate in Clinical Nutrition, Dr. Kevin Ritzenthaler will look at a detailed history of your current health status to develop a plan that is just for you.
