This essay explores the consequences of the biomedical model in understanding health and illness, contrasting it with theories like functionalism and social constructionism. The biomedical model, which primarily focuses on biophysical and genetic malfunctions, is examined for its limitations in considering psychological, environmental, and social determinants of health. The essay highlights how the model's emphasis on laboratory tests over patient history, its neglect of psychological influences, and its disregard for social behaviors like lifestyle and eating habits can lead to incomplete diagnoses and ineffective prevention strategies. Alternative approaches, such as the biopsychosocial model, are presented as more comprehensive frameworks that account for the multifaceted nature of health and illness. The essay concludes by advocating for a holistic approach to healthcare that integrates social determinants to improve diagnostic accuracy and promote overall well-being, emphasizing the importance of prevention over cure.
