St. Luke's Clinic – Nutrition Services: Twin Falls

Our registered dietitians work with patients of all ages, specializing in weight management, malnutrition assistance, enteral feeding evaluation and recommendations, gastrointestinal disorders, allergies, and cardiac diet education.

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.
