One study in Archiv Fur Kriminologie concluded that you can’t survive more than 8 to 21 days without food and water. People on their deathbed who are using very little energy may live only a few days or a few weeks without food and water. Water is much more essential to your body than food.
If a person stops eating or drinking because of their reduced appetite, this may be hard to accept, but it is a normal part of the dying process. If they stop drinking, their mouth may look dry, but this does not always mean they are dehydrated. It is normal for all dying people eventually to stop eating and drinking.
If you stop eating and drinking, death can occur as early as a few days, though for most people, approximately ten days is the average. In rare instances, the process can take as long as several weeks.
While the pre-active stage lasts for about three weeks, the active stage of dying lasts roughly three days. By definition, actively dying patients are very close to death, and exhibit many signs and symptoms of near-death.
Pulse and heartbeat are irregular or hard to feel or hear. Body temperature drops. Skin on their knees, feet, and hands turns a mottled bluish-purple (often in the last 24 hours) Breathing is interrupted by gasping and slows until it stops entirely.
Signs that the body is actively shutting down are:
Five Physical Signs that Death is Nearing
How long can a 90 year old live without food? One study in Archiv Fur Kriminologie concluded that you can ‘t survive more than 8 to 21 days without food and water. People on their deathbed who are using very little energy may live only a few days or a few weeks without food and water.
When a person is just hours from death, you will notice changes in their breathing:
After three to five days of not drinking water, your organs begin to shut down, especially the brain, which could have lethal consequences including fainting, strokes and in extreme cases, even death.
The brain is the first organ to begin to break down, and other organs follow suit. Living bacteria in the body, particularly in the bowels, play a major role in this decomposition process, or putrefaction.
What happens when someone dies? In time, the heart stops and they stop breathing. Within a few minutes, their brain stops functioning entirely and their skin starts to cool. At this point, they have died.
One study in Archiv Fur Kriminologie concluded that you can’t survive more than 8 to 21 days without food and water. People on their deathbed who are using very little energy may live only a few days or a few weeks without food and water.
This difficult time may be complicated by a phenomenon known as the surge before death, or terminal lucidity, which can happen days, hours, or even minutes before a person’s passing. Often occurring abruptly, this period of increased energy and alertness may give families false hope that their loved ones will recover.
In the last hours before dying a person may become very alert or active. This may be followed by a time of being unresponsive. You may see blotchiness and feel cooling of the arms and legs. Their eyes will often be open and not blinking.
The end-of-life period—when body systems shut down and death is imminent—typically lasts from a matter of days to a couple of weeks. Some patients die gently and tranquilly, while others seem to fight the inevitable. Reassuring your loved one it is okay to die can help both of you through this process.
