Role of the Registered Dietician Nutritionist in the Management of Rheumatic Diseases


Registered dietitian nutritionists (RDNs) can help patients with rheumatic diseases in making the most appropriate nutrition choices to manage symptoms and prevent or treat comorbidities. The RDN is an integral part of the health care team and can provide information about dietary issues that can guide health care professionals in their treatment, management, and interaction with patients.

What Does a Registered Dietitian Nutritionist Do?

A nutrition assessment provides the basis for the RDN’s intervention. Evaluation of the patient’s diet and lifestyle habits includes:

  • Diet recall/food frequency for overall assessment of energy, protein, fluid, and nutrient intake
  • Nutrient excesses and deficiencies
  • Food allergies and intolerances
  • Growth and development
  • Evaluation of pertinent labs
  • Gastrointestinal symptoms
  • Supplement use, including vitamin/mineral supplements, herbal supplements, and nutritional supplement drinks
  • Medical history
  • Activity level
  • History of emotional eating in response to pain, fatigue, and stress
  • Shopping, cooking, and restaurant habits
  • Family and social support/influences
  • Readiness for change

The RDN assesses each patient to determine if their diet contributes to symptoms and comorbidities, such as overweight or obesity, heart disease, diabetes, or osteoporosis. Supporting materials, such as menu ideas and recipes, may be provided to support dietary recommendations and improve patient adherence.

Some RDNs specialize in food allergies and may recommend elimination or exclusion diets to determine if there are any specific foods that may exacerbate symptoms and digestive issues. The RDN also addresses emotional eating issues, which may arise in response to chronic pain and fatigue. Weekly or bi-monthly support is often recommended to help the patient achieve nutrition goals.

Where Does a Registered Dietitian Nutritionist Work?

  • Hospitals
  • Outpatient clinics
  • Physician offices
  • Community programs
  • Food service
  • Schools
  • Wellness programs
  • Nursing homes

Private practice RDNs often work independently or act as a part of a health care team in a clinical setting.

What Kind of Training Does a Registered Dietitian Nutritionist Have?

An RDN must have the minimum of an undergraduate degree in nutrition science in addition to completion in a one-year accredited internship in a healthcare facility, community agency, or foodservice corporation, or combined with undergraduate or graduate studies. An internship will typically be 6 to 12 months. After completion of an accredited internship, they must pass a national registration exam and complete ongoing continuing professional education to maintain licensure. The Commission on Dietetic Registration is the national credentialing agency for registered dietitians.
