Patient's Success: Shannon's Story
Shannon has been through the program at Root Cause Medical and her migraines have completely gone away! She had tried everything to get rid of them, but nothing worked until we helped her get to the root cause.
We have excellent success in helping patients handle their migraines, digestive issues, autoimmune disease, hormonal imbalances – a lot of things!
If you’re looking for a team of doctors that will look at your body as a whole and help you get to the Root Cause."
Patient's Success: Victoria M's Story
I had been suffering with chronic fatigue, nerve pain, weight gain and hair loss. I had no “disease”, but I was unable to live my busy life due to complete exhaustion.
A series of custom IVs gave me my life back. The IVs were done as part of an overall program, but without them I am sure my healing would have taken several more months.
Thank you to the Doctors at Root Cause Medical Clinic.
Patient's Success: Theresa V's Story
Thank you so much for introducing me to IV therapy. When I started care I was not sleeping and having a lot of hot flashes, which in turn caused me to feel unrested in the morning.
Patient's Success: Pam E's Story
I wanted to let you know how much the UBVI has helped me with my Lyme symptoms. When I first came to the clinic my brain fog and joint pains were rather debilitating.
Now I feel so much better. Honestly, I thought I would never feel good again. Thanks for helping me feel like me again!
