Abstract
The building of life stress, well expressed by the concept of allostatic load, plays an important part in all phases of endocrine illness. Allostatic load refers to the cumulative burden of both stressful life events and chronic stress. When environmental challenges exceed the individual ability to cope, allostatic overload ensues. Assessment of allostatic load/overload by clinical measurements including indices and rating scales, in addition to biomarkers, offers a characterization of the person's psychosocial environment that is missing from current formulations. Consideration of allostatic load in endocrinology may shed light on a number of clinical issues: interpretation of abnormal hormone values that lack explanations; coping with the various phases of illness; maladaptive illness behavior; response to treatment; presence of residual symptoms; health-damaging lifestyle habits. Addressing allostatic load calls for innovative models of endocrine outpatients with multidisciplinary organization of care, extended time for the interview, focus on rehabilitation. We provide an overview on the mechanisms of allostatic load, how it can be assessed, its potential role in endocrine disturbances, and how its consideration may lead to a needed innovation in patient care.
