Terminal dehydration is dehydration
Dehydration
In physiology and medicine, dehydration is defined as the excessive loss of body fluid. It is literally the removal of water from an object; however, in physiological terms, it entails a deficiency of fluid within an organism...

 to the point of death, potentially as a suicide method. Some scholars make a distinction between "terminal dehydration" and "termination by dehydration". Courts in the United States generally do not recognize prisoners as having a right to die by voluntary dehydration, since they view it as suicide. As terminally ill patients approach death, their desire to consume food and fluids tends to diminish. Although it is common practice to hydrate such patients, there is some evidence that dehydration may actually be more comfortable for these patients than hydration.

Progression

During terminal dehydration, the usual symptoms of dehydration, such as headache

 and leg cramps, can occur. Dehydration can be hard to bear, and requires patience and determination, since it takes from several days to a few weeks. This means that unlike many other suicide methods, it cannot be accomplished impulsively. However, a "point of no return" can eventually be reached at which, should it be desired to abort the terminal dehydration, rehydration cannot be accomplished through simple oral rehydration therapy

. 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.

Voluntary

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 in Oregon (where physician-assisted suicide is legal) 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. There can be a fine line between terminal sedation

.

Numerous studies have shown that for terminally ill patients who choose to die, deaths by terminal dehydration are generally peaceful, and not associated with suffering, when supplemented with adequate pain medication.
All ages may feel sudden head rushes, dizziness, and loss of appetite, as well.

Involuntary

In the Netherlands, debate has broken out about terminal dehydration, which is referred to as versterven. There have been accusations that involuntary dehydration takes place in nursing homes.
