Background/Objectives: This study aimed to determine the prevalence of malnutrition and sarcopenia risk among patients hospitalized in gastroenterology clinics across different geographical regions of Turkey, to identify their risk factors, and to evaluate their associations with clinical outcomes. Methods: A total of 1051 patients admitted to 36 gastroenterology clinics across six geographical regions of Turkey during the week of 14 November 2024 were evaluated in a cross-sectional design. The nutritional status of the patients was assessed using the NRS-2002 questionnaire, while the risk of sarcopenia was evaluated with the SARC-F questionnaire. Demographic data, clinical diagnoses, disease severity scores, and comorbidities were also recorded and analyzed. Results: Of the patients included in the study, 54.7% were female, and the mean age was 61.7 ± 17.2 years. The prevalence of malnutrition risk was 27.8%, while the prevalence of sarcopenia risk was 32.7%. Patients with malnutrition risk had a lower BMI (24.7 ± 5.3 vs. 27.1 ± 5.4, p < 0.001) and were older (67.6 ± 16.0 vs. 56.5 ± 17.1, p < 0.001). The risks of sarcopenia and malnutrition were significantly higher in patients with liver cirrhosis (40.7% malnutrition; 54.5% sarcopenia), gastrointestinal malignancy (50.5%; 44.2%), and diabetes mellitus. Logistic regression analysis identified older age, male sex, and presence of malignancy as independent risk factors for malnutrition, whereas older age, female sex, presence of malnutrition, liver cirrhosis, and heart failure were independent risk factors for sarcopenia. A strong correlation was also found between malnutrition and sarcopenia (r = 0.544, p < 0.001). Conclusions: Approximately one-third of patients hospitalized in gastroenterology clinics across Turkey are at risk of malnutrition and sarcopenia. These conditions are particularly associated with malignancy, cirrhosis, and metabolic comorbidities. Our findings highlight the necessity of systematic nutritional and sarcopenia screening upon hospital admission.
