The sociology of health and illness, alternatively the sociology of health and wellness (or simply health sociology), examines the interaction between society and health. The objective of this topic is to see how social life affects morbidity and mortality rate, and vice versa. This aspect of sociology differs from medical sociology in that this branch of sociology discusses health and illness in relation to social institutions such as family, employment, and school, and also interfaces more extensively with sociology of the body. The sociology of medicine by contrast tends to focus specifically on the patient-practitioner relationship and the role of health professionals in society. The sociology of health and illness covers sociological pathology (causes of disease and illness), reasons for seeking particular types of medical aid, and patient compliance or noncompliance with medical regimes.
