GAS-General Adaptation Syndrome
AKA Neuroendocrine Response
A 3 stage reaction that describes how the body responds to stressors through the alarm reaction, resistance stage, and the exhaustion stage
Primarily in lives the
- ANS and endocrine system
- initiated by the pituitary gland:causes hypothalamus to secrete endorphins
Alarm reaction
Fight or flight response
- the body is alerted to stressors
- HR,BP, cardiac output, epinephrine and norepinephrine increased, blood flow to muscles increased, blood glucose increased
- lasts minutes to hours
Resistance stage
Body tries to cope(adapt) to stressors and to limit the stressor to smallest area of body that can deal with it
- patient may be irritable,restless,decreased initiative.
- body is trying to return to normal and fix any damages but can become ill if stress is not relieved due to powerful hormone fluctuations
Exhaustion stage
Too much to adjust to
Patient may be:depressed,depleted, slowed down, near death
Factors influencing the response to stressors
- Nature of stressor
- Number of stressors to be coped with at one time
- Duration of exposure to stressor
- Experience with comparable stressor
Nature of stressor
What it means to the person. What some find a minor stressor may be major to someone else
Duration of exposure
If stressor is extended beyond coping ability, person becomes exhausted and eventually dies
LAS- Local Adaptation Syndrome
More localized to a specific area/ or inflammatory response
