SSc is a chronic multi-system disease with wide-reaching consequences. Gastrointestinal features are present in over 90% of cases and these, together with other disease manifestations, may lead to nutritional decline. This produces substantial morbidity, including reliance on enteral support and even parenteral nutrition-dependent intestinal failure. These complications carry an associated mortality. Up to 18% of patients with SSc are reported to be at high risk of malnutrition [as assessed by Malnutrition Universal Screening Tool (MUST) criteria], with risk increasing with disease severity. Little is known about this decline, its rate of progression and how it affects the individual. Few case series report on nutritional interventions. Most current interventions are based on experience in other diseases. The development of specialist knowledge of SSc-related gastrointestinal disease management and nutritional screening and interventions is required. This paper reviews current knowledge relating to malnutrition and its management in SSc.
