While organs deteriorate over a lifetime along with the rest of your body, disease or genetics may ultimately destroy one specific organ while the rest of your body remains relatively healthy. Depending on which organ is wearing down, there are many life-sustaining measures short of transplantation that can be taken to improve your health. For instance, dialysis helps a person with damaged kidneys. However, the rest of the body is negatively affected by these measures. A person on dialysis has a higher risk of cardiovascular disease because the process can reduce the amount of antioxidants that normally fight toxins within the body.
