Self-diagnosis, which involves using the Internet to identify health problems, is becoming an increasingly common practice and trend in modern society. Although the Internet provides quick access to large amounts of information, it can lead to misdiagnosis, excessive anxiety, and inappropriate self-medication. Self-diagnosis is becoming part of the culture of health in which today's consumer society strives for youth, vitality and energy, encouraging consumers to use different strategies to achieve the ideal of a healthy body. The main goal of this research is to examine the use of the Internet as a tool for self-diagnosis and to investigate the attitudes of students at the Faculty of Philosophy in Split. The research was conducted during September 2024 through an online questionnaire on a sample of 154 students. The results suggest that there are gender differences in attitudes towards online health information, while years of study and financial status do not play a significant role. The experience of searching for health information may differ between socio-demographic groups, therefore it is important to further investigate this phenomenon within the Croatian socio-cultural context.
