Stress and Glucose metabolism: A Review
2018
Stress is an inescapable fact of life. The perceived stress induces endocrine alterations characterized
by the activation of hypothalamo-pituitary-adrenal axis and sympathetic adreno-medullary axis. The
glucocorticoids and catecholamines which are secreted in response to stress induce variations in the
physiology and behavior that help the individual to adapt to changing demands of the body. Glucocorticoids
are known to play a central role in inducing the stress related pathophysiology. These hormones induce
hypermetabolism in order to cope up with the increasing energy demands of the body. However when the
stress is persistent the body adapts itself to continuous demands and starts regulating the metabolism
at higher levels than the normal, termed as allostasis. This overwhelming load on the body will predispose
the individual for the development of diseases. This mini-review focuses on long term chronic stress
induced alterations in glucose metabolism and development of insulin resistance and glucose intolerance
as a result of long term allostatic regulation.
