Kidneys
Renal losses of salt and fluid can lead to hypovolemic shock. The kidneys usually excrete sodium and water in a manner that matches sodium intake and water intake.Diuretic therapy and osmotic diuresis from hyperglycemia can lead to excessive renal sodium and volume loss. In addition, there are several tubular and interstitial diseases beyond the scope of this article that cause severe salt-wasting nephropathy. Skin
Fluid loss also can occur from the skin. In a hot and dry climate, skin fluid losses can be as high as 1 to 2 liters/hour. Patients with a skin barrier interrupted by burns or other skin lesions also can experience large fluid losses that lead to hypovolemic shock. Third-spacing
Sequestration of fluid into a third space also can lead to volume loss and hypovolemic shock. Third-spacing of fluid can occur in intestinal obstruction, pancreatitis, obstruction of a major venous system, vascular endothelium or any other pathological condition that results in a massive inflammatory response. Pathophysiology
Blood loss
Hemorrhagic shock is due to the depletion of intravascular volume through blood loss to the point of being unable to match the tissues demand for oxygen. As a result, mitochondria are no longer able to sustain aerobic metabolism for the production of oxygen and switch to the less efficient anaerobic metabolism to meet the cellular demand for adenosine triphosphate.
Sex therapy has also influenced the emergence of sexual medicine and exploring integrative approaches to sex therapy, in addition to reducing or eliminating sexual problems and increasing sexual satisfaction for individuals of all stages of life. Health therapists, educators, and counselors are conducting research and administering surveys to fully understand normative sexual function – what most people do and experience as they grow older and live longer. Aging and sexuality
Both physical and emotional transformation throughout various stages of life can affect the body and sexuality. The subsequent decline in hormone levels and changes in neurological and circulatory functioning may lead to sexual problems such as erectile dysfunction or vaginal pain. These physical changes often affect the intensity of youthful sex and may give way to more subdued responses during middle and later life. Issues with low libido and sexual dysfunction are usually considered to be a byproduct of old age. The emotional byproducts of maturity, however — increased confidence, better communication skills, and lessened inhibitions — can help create a richer, more nuanced, and ultimately satisfying sexual experience. During AARPs last surveys in 1999, 2004, and 2009 statistics show well-being among older adults has increased; however, overall sexual satisfaction has decreased. Nevertheless, older adults believed that an active sexual life offers great pleasure and contributes materially to overall emotional and physical health. Older adults
Over the years, little attention has been paid to older adults and sexuality.
