When it comes to long-term health conditions, obesity is considered a complex and common disease that rapidly affects overall quality of life, significantly contributing to increased morbidity and mortality rates, as well as shortening life expectancy. Obesity is not just an aesthetic issue but a serious health condition that has a profound impact on numerous aspects of life. This complex field of research requires a comprehensive approach to identify the most effective ways of preventing, diagnosing, and treating obesity, which already represents a global problem, while also taking individual characteristics into account. The purpose of this scientific paper is to improve the understanding of the complex relationship between body weight and the perception of quality of life, with the main goal being to determine how and to what extent excessive body weight affects the functioning and quality of life of obese individuals. The research methodology included a qualitative interview method. Five overweight individuals, aged 53 to 75 years, participated in the interviews. A significant characteristic of the study is that all participants are facing excessive body weight, placing a special focus on this aspect of health in older age. Based on the conducted research and obtained results, the conclusions indicate that self-perception of quality of life does not depend on age and gender. Furthermore, excessive body weight indeed presents a problem in performing both daily and social activities. In conclusion, we can say that the level of self-assessment of quality of life, along with life satisfaction, is rated as very low and does not indicate differences between the genders or ages of the examined obese individuals.
