Medical models are frameworks used to understand health and illness. They help healthcare professionals explain how diseases develop, how they affect the body, and how they can be treated. Common models include the biomedical model, which focuses on biological factors, and the biopsychosocial model, which considers psychological and social influences alongside biological aspects. These models guide research, diagnosis, and treatment decisions. For instance, the biomedical model emphasizes medical interventions, while the biopsychosocial model encourages a more holistic approach, integrating mental health and social support into patient care. Understanding these models is essential for effective healthcare delivery.
