Obesity: A Comprehensive Look at Causes and Consequences

Research from the National Institute of Psychiatry 'Ramón de la Fuente Muñiz' highlights the role of the brain, environment, stress, and habits that directly influence the mechanisms of appetite and satiety. Obesity was described as a global public health crisis, associated with multiple chronic diseases and a complex interaction of biological, social, and environmental factors, according to specialists from the National Institute of Psychiatry 'Ramón de la Fuente Muñiz' (INPRFM). During an academic presentation, researcher Edith Sánchez Jaramillo, from the Laboratory of Molecular Neuroendocrinology, explained that obesity cannot be understood as a simple lack of willpower, but as a complex phenomenon determined by multiple variables. A multifactorial disease with systemic impact. The specialist warned that obesity is linked to conditions such as diabetes, cardiovascular diseases, cancer, metabolic syndrome, depression, and anxiety, which amplifies its impact on public health. In this context, she emphasized that genetic, environmental, and social factors interact constantly, creating a scenario that favors the development and maintenance of this condition. She also noted that the modern environment, characterized by sedentary lifestyles, exposure to advertising, and intensive use of digital technologies, contributes to modifying eating behavior patterns. The brain as the axis in food regulation. One of the central elements of the analysis was the role of the central nervous system. According to the researcher, the brain regulates appetite and satiety through complex circuits that integrate metabolic, emotional, and reward signals, which explains the relationship between eating and emotional states. These mechanisms can be altered by factors such as stress or anxiety, as well as by constant exposure to stimuli that encourage the consumption of high-calorie foods. In this sense, she highlighted that eating does not respond only to biological needs, but also to behavioral and emotional processes, which requires a broader understanding of the phenomenon. Mental health: an essential component of the approach. The specialist emphasized that mental health has become a fundamental axis of comprehensive well-being, and its inclusion in the analysis of obesity represents a significant advance. She indicated that there is currently greater openness to address these issues, which allows for the development of more effective strategies, especially in young populations. The comprehensive approach implies considering both biological and psychosocial determinants, with the aim of improving prevention and treatment. Research and prevention: the basis for new strategies. During the seminar cycle 'Current Challenges of Infectious Diseases,' where this research was presented, the importance of basic biomedical research as a tool to understand the mechanisms that regulate food was highlighted. The specialist stressed that scientific knowledge allows for the development of more precise prevention and treatment strategies, as well as for promoting healthy habits from a comprehensive perspective. Specialized care and institutional capabilities. INPRFM was identified as a reference institution in Mexico in terms of clinical care, research, and training of specialists. Among the services it offers to the adult population are areas such as affective disorders, addictions, eating behavior, psychiatric genetics, and sleep medicine, which allows for a multidisciplinary approach to obesity and its comorbidities.
