Orville Weyrich, N.M.D.

Dr. Weyrich uses naturopathic and functional medical approaches to treat fatigue and malaise associated with low thyroid and adrenal function, disorders associated with the digestive tract - from GERD down to hemorrhoids, chronic pain and fibromyalgia, as well as auto-immune disorders.  Dr. Weyrich emphasizes finding and correcting the cause, rather than only covering up the problem.

There is a growing body of evidence that disorders as varied as autism, attention deficit/hyperactivity, epilepsy, fibromyalgia, chronic fatigue, irritable bowel, inflammatory bowel, and other chronic and degenerative diseases share common features of gut dysbiosis, leaky gut, food sensitivities, nutritional deficiencies, environmental toxicity, and hormone imbalances. As such, these disorders all respond to variations on the same functional medicine diagnostic work-up and naturopathic treatment protocols.

Dr. Weyrich earned a PhD in Organic Chemistry from the University of Tennessee and graduated from Southwest College of Naturopathic Medicine. He is licensed to practice as a Naturopathic Medical Doctor (NMD) in Arizona.
