Experience the advantage of Natural Health through Functional Medicine and IV Therapy Services

The Functional Medicine MD is the Premier Functional Medicine and IV Therapy Clinic in McHenry, Lake and Boone Counties.

Founded in 2018 by Dr. Lela Iduna – a Yale trained Medical Doctor and IFM certified functional medicine practitioner with over 25 years of experience in medicine. 

Functional medicine looks at the root cause of the disease. In traditional medicine, we do a diagnosis to the symptom(s) and match a pill to it.  In Functional Medicine, we describe this method as similar to spraying the spots on the leaves of a tree.

Looking at the root cause, looks at the soil and the root system.  What is causing the spots on the leaves?  Is the soil healthy – filled with nutrients and free from germs and toxins?  Are the roots strong and able to absorb the nutrients?  When we fix the soil and the root system, we fix the spots on the leaves and don’t need to keep spraying.

This looking at the root cause model is applied to all “diseases,” from a common cold to diabetes, Alzheimer’s and even cancer – resulting in a more thorough treatment.

Health is not simply the absence of disease.

Health is the perfect balance a system, creating a sense of well being. This cannot be accomplished by treating each symptom in isolation to the rest of the system or waiting till we cannot deal with the symptom and it is limiting our capacity to function fully.

The human body is a complex system with many parts, each one interconnected to the other by several pathways. 

If one pathway breaks down, there are several others still supporting the body to function. Much like several pillars holding up a bridge, when several of the foundational pillars are damaged, the integrity of the bridge become compromised. Similarly, when the human body starts showing obvious signs of disease, several foundational pathways have been compromised, now making it urgent to seek help.

Healing and repairing these base pillars is thus the striving of functional or integrative medicine, before they cause a devastating problem. We partner with you to stay healthy and live life the best you can!
