St. Luke's Clinic – Bariatric Nutrition

As an important part of St. Luke’s bariatric surgery program, our bariatric registered dietitians provide personal pre-operative as well as post-operative nutrition counseling to maximize your opportunities for successful weight loss and weight loss maintenance. We regularly lead support groups in addition to directing cooking and bariatric lifestyle classes.

A physician referral is necessary for all appointments. It gives the dietitian the medical information needed to plan an appropriate and individualized counseling session and is also required for insurance. Please check with your insurance company to see if your medical condition is covered for dietitian services.
