description Gastrointestinal (GI) involvement is highly prevalent in systemic sclerosis (SSc) and significantly affects patient quality of life and clinical outcomes. This study investigates the potential of undernutrition scores, namely the Control of Nutritional Status (CONUT) score and the Prognostic Nutrition Index (PNI), in predicting GI involvement in patients with SSc. A total of 82 patients diagnosed with SSc were enrolled in this cross-sectional study. Participants were evaluated using the UCLA Scleroderma Clinical Research Consortium Gastrointestinal Tract 2.0 (UCLA GIT 2.0) tool, which assesses the severity of GI symptoms and their impact on health-related quality of life. Malnutrition was assessed using CONUT and PNI scores derived from routine laboratory parameters. The correlation between these malnutrition indices and the UCLA GIT 2.0 scores was analyzed to determine the predictive value of malnutrition in GI involvement. The study found that patients with higher CONUT scores, indicating malnutrition, had significantly higher total UCLA GIT 2.0 scores. A moderate positive correlation was observed between CONUT scores and total UCLA GIT 2.0 scores ( r  =.539; p
