Scott Rigden, MD


Dr. Scott Rigden, M.D. is board certified in Family Practice and Bariatrics. He has been in the private practice of medicine since 1976 and at his present location in the Phoenix, Arizona area since 1984. His medical practice is unique in that it focuses on evaluation and treatment of obesity and related metabolic problems, as well as chronic illnesses such as Chronic Fatigue Syndrome and Fibromyalgia, with a Functional Medicine approach.

Dr. Rigden was born and raised in the St. Louis area and won the Albert C. Murphy academic scholarship to attend Cornell University. After graduating from Cornell cum laude, he attended St. Louis University Medical School and then completed a three-year Family Practice Residency program in Lansing, Michigan.  He served his first seven years of medical practice in Byron, Illinois, where he was one of only several medical doctors in the entire county, with the nearest hospital twenty-two miles away. To further his professional growth and development, he relocated to the Phoenix, Arizona area in 1984 to have more time to teach, conduct and publish clinical research, in addition to being a busy practitioner.

Scott has a special empathy for the obese patient that probably began with his youth and teen years. He was obese and had to endure the nickname of “Pork chops” as he struggled to develop self-esteem. In high school he weighed sixty-five pounds more than he does now. In addition, he was raised in an extended family that had grave problems with obesity, diabetes, and heart disease. In medical school and residency he noticed the plight of the post-operative intestinal bypass surgical patients and researched and published the first scientific paper on the long-term follow-up of these individuals, documenting their post-op problems. As a new family practice physician in rural Illinois in the 1970’s, he treated thousands of patients, many of them overweight. While there, he made a professional commitment to reach out to the obese patient and began intensive studies in nutrition and weight management.  This led to fulfilling the criteria to become a board certified physician in the specialty of bariatrics (the management of obesity and related problems). He has worked with obese patients since 1976. Since then, he has authored a number of articles on obesity and lectured extensively both to lay and professional audiences. He regularly teaches continuing medical education courses to his peers. His first book, Take It Off-the Weight Workbook, has sold several thousand copies. His recent book, The Ultimate Metabolism Diet-Eat Right for Your Metabolic Type, published by Hunter House, has received great reviews and has been released in Italy, India, Bulgaria as well as the United States. He has been featured locally on a number of radio and television programs. Dr. Rigden has been quoted in Prevention magazine and USA Today. Dr. Rigden has been recognized by his peers with positions on the Board of Directors of the American Society of Bariatric Physicians and is a recipient of the distinction of being named a Fellow of the ASBP, an honor only previously given fifteen times in the long history of the organization. He is considered one of the leading authorities on a metabolic cause of obesity called Metabolic Syndrome, also called Syndrome X.

Urged on by numerous desperate patients in the 1980’s, Dr. Rigden has been extensively involved with the diagnosis and treatment of Chronic Fatigue Syndrome and Fibromyalgia for many years. He has lectured, published and researched these problems extensively and was named the HealthComm Researcher of the Year in 1992 for his pioneering work on Chronic Fatigue Syndrome and Enterohepatic Detoxification. Often asked to teach physicians about CFS/Fibromyalgia at continuing education programs, he has served on the clinical faculty of three medical schools. Dr. Rigden has been one of the pioneers in the Functional Medicine movement, and is recognized nationally for his contributions to this field and application of nutritional therapies to chronic illness.

Dr. Rigden received a great honor at the International Annual Functional Medicine Meeting in Tucson, Arizona in 2003, when he was awarded the Institute of Functional Medicine Outstanding Contribution Award from Dr. Jeffrey Bland, Chairman of the board of the IFM. Dr. Bland stated, “…the Institute, on behalf of the many colleagues and patients who have benefited from Dr. Rigden’s expertise, recognizes and appreciates the unstinting and consistent leadership exemplified in his twenty years of clinical and education contributions to the development of Functional Medicine.”
