Introduction: Obesity is a global health problem associated with various diseases, such as type 2 diabetes, hypertension and heart disease. Causes include a combination of genetic, psychological, social, and economic factors, and treatment is based on dietary changes, increased physical activity, medications, and bariatric surgery. Methods: The research was conducted between May 12, 2024. and 19.05.2024. through a digital questionnaire on the Google Forms platform. Students of undergraduate physiotherapy and nursing studies at the University of the North participated in the research. A validated questionnaire "Knowledge about bariatric surgery" with 14 questions was used, taken from the work of Abbas A. Altaf from the Saudi Medical Journal. Results: Analysis of the results revealed that all respondents are aware of the health risks associated with obesity, such as type 2 diabetes and heart disease. Most students understand the concept of obesity and the possibility of bariatric surgery as one of the methods of treating obesity. Also, exercise is recognized as a key component in the long-term approach to obesity treatment. However, views on the need for bariatric surgery were divided, with variations in opinion on its application. Discussion: A comparison with research by Abbas A. Altaf shows a high level of awareness of the health risks of obesity in both groups, with slightly better understanding among physiotherapy and nursing students. Significant differences were observed in the knowledge of the definition of morbid obesity, where students showed better information. Although the perception of bariatric surgery as a medical procedure is similar, greater uncertainty was observed regarding the indications for its use, which highlights the need for additional education.
