Introduction: According to epidemiological studies conducted in Mongolia over the past decade, diseases of the digestive system have consistently ranked second in terms of morbidity and fourth in mortality. With the rapid advancement of technology, sedentary lifestyles and unhealthy living habits have become more prevalent among the population, leading to a trend of digestive disorders affecting younger age groups. Therefore, investigating the prevalence, pathological changes, and risk factors associated with gallbladder and pancreatic diseases among university students has become the rationale for this study. Objective: To study the prevalence of gallbladder and pancreatic disorders and determine some of the associated risk factors. Methodology: 200 students from the first to sixth year were selected through random sampling based on the WHO age classification. Data collection included a structured questionnaire and ultrasound examination using the SUN-800D device. Diagnostic criteria followed the national clinical guidelines for acute cholecystitis. Results: Out of 200 participants, 120 (60%) were female and 80 (40%) were male. Among them, 128 students (64%) reported skipping breakfast regularly, and 147 (73.5%) did not consume an adequate amount of fluids daily. Ultrasound examinations revealed that 104 students (52%) had some form of gallbladder or pancreatic abnormality. Additionally, gallstones were detected in 1 student (0.5%), and gallbladder polyps were found in 5 students (2.5%). Conclusion Gallbladder and pancreatic abnormalities were observed in 52% of the participants. Among the associated risk factors, 64% of students reported skipping breakfast, and 73.5% had inadequate daily fluid intake. The ultrasound findings showed that 47% had biliary sludge, 32% had gallbladder kinking, and 48.5% had increased pancreatic echogenicity.
