GI Nutrition Therapy

Achieving and maintaining good nutrition is a key component of managing the troubling symptoms of gastrointestinal (GI) conditions. A proper diet also helps support the body’s energy levels and immune system, and can help prevent micronutrient deficiencies and malnutrition.

GI Nutrition Services, part of the Division of Gastroenterology and Hepatology, play an integral role in Michigan Medicine’s comprehensive, multidisciplinary approach to GI care. Together with GI physicians, nurses, clinical psychologists, pelvic floor physical therapists and other specialists, we partner with patients to promote well-being and optimize quality of life.

Our registered dietitian nutritionists provide individualized nutrition care and counseling for patients with a range of GI conditions, including:

Specialized Nutrition Services

To help patients modify their dietary habits to achieve better nutrition and reduce GI symptoms, we rely on evidenced-based medical nutrition therapy and individualized counseling.

We specialize in specific diets that can significantly improve gastrointestinal symptoms, including:

      • The low FODMAP diet for IBS
      • Specific elimination diets for eosinophilic esophagitis
      • Low oxalate, low residue, and gluten-free diets

During the initial consultation (approximately one hour), the patient meets with a registered dietitian nutritionist for a comprehensive health assessment including a review of GI diagnosis and symptoms, diet history, current intake of nutrients, lifestyle and behavioral factors.

Patients are educated on strategies for optimizing their diets to achieve their specific goals. For example, for the most common GI disorder we address, IBS, patients learn how the low-FODMAP diet can provide symptom relief.

Patients receive nutritional recommendations individualized to meet their nutrition and health goals, including symptom management and weight management. Nutritional plans are added to each patient’s medical chart for coordination with the rest of the GI care team.

One or more shorter follow-up appointments (approximately 30 minutes) with GI Nutrition Services are usually scheduled to monitor progress, answer questions and address concerns.
