Register to read the introduction… With enough stress, humans are at a higher risk for developing adult-onset diabetes. This is due to the body releasing glucose and fatty acids into the bloodstream during stress, again in order to feed the exerting muscles. At the same time, the body tends to block insulin production, and we remember from basic physiology that insulin is the key hormone that allows glucose to enter the cells. Without insulin there to make this happen, excess glucose remains in the blood if it’s not used by the muscles. Continued stress responses over time can eventually cause the uptake of glucose into the cells to be hindered, thereby creating a diabetic condition. Sapolsky goes on to explain how stress in our lives can also lead to loss of libido and reproduction. During periods of stress, males can see a decrease in circulating testosterone due to a release of specific hormones in the brain which basically shut down the activity of the testes, which are responsible for testosterone release. On the female side, the author tells us that studies have shown how stress suppresses estrogen production, which in turn disrupts sexual behavior in women. (Sapolsky, 1994. p. …show more content…
Compared to younger generations, the elderly function just the same as long as they are not stressed. Once a stressor is introduced, the elderly may have numerous problems coping with that stress. There may be a lack of a stress response, or a decreased sympathetic response because the heart itself and the blood vessels have lost their elasticity which allow them to dilate and constrict, and therefore may not be able to respond appropriately to physiological changes. Another problem may be that they have too much of a stress response. It will take longer for hormone levels to return to their pre-stress levels and return to baseline. The author concludes this section by revealing that in more than a dozen species, excess glucocorticoid levels is the cause of death during aging. (Sapolsky, 1994, p.
