Suicide Methods - Dehydration

Dehydration

Death from dehydration can take from several days to a few weeks. This means that unlike many other suicide methods, it cannot be accomplished impulsively. Those who die by terminal dehydration typically lapse into unconsciousness before death, and may also experience delirium and deranged serum sodium. Discontinuation of hydration does not produce true thirst, although a sensation of dryness of the mouth often is reported as "thirst." The evidence this is not true thirst is extensive and shows the ill feeling is not relieved by giving fluids intravenously, but is relieved by wetting the tongue and lips and proper care of the mouth. Patients with edema tend to take longer to die of dehydration because of the excess fluid in their bodies.

Terminal dehydration has been described as having substantial advantages over physician-assisted suicide with respect to self-determination, access, professional integrity, and social implications. Specifically, a patient has a right to refuse treatment and it would be a personal assault for someone to force water on a patient, but such is not the case if a doctor merely refuses to provide lethal medication. But it also has distinctive drawbacks as a humane means of voluntary death. One survey of hospice nurses found that nearly twice as many had cared for patients who chose voluntary refusal of food and fluids to hasten death as had cared for patients who chose physician-assisted suicide. They also rated fasting and dehydration as causing less suffering and pain and being more peaceful than physician-assisted suicide. Other sources, however, have noted very painful side effects of dehydration, including seizures, skin cracking and bleeding, blindness, nausea, vomiting, cramping and severe headaches. There can be a fine line between terminal sedation that results in death by dehydration and euthanasia.
