how long can you live without food and water in a coma?
62711
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.

As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this. Factors that may change how much water a person needs include: age.

If untreated, life-threatening coma or respiratory failure could occur within 7 to 10 days and most will die within several months. Upon any lapse of treatment, classic MSUD can cause brain damage. People with the disease are particularly prone to crisis during illness, infection, fasting, or after surgery.

A coma is not like sleeping. It takes months or years to recuperate after a coma and the patient may require more sleep than before because it takes a lot of energy to make this recuperative journey.

(If the individual is dehydrated or over-hydrated, the time may range from approximately one to three weeks.) In situations of voluntary refusal of food and hydration, death typically ensues on a similar time frame, although the early use of ice chips or sips of water to reduce thirst may delay this slightly.

In the short term, a person in a coma will normally be looked after in an intensive care unit (ICU). Treatment involves ensuring their condition is stable and body functions, such as breathing and blood pressure, are supported while the underlying cause is treated.

Experts believe it is possible for the human body to survive without food for up to two months.

Time Frame for Oxygen Deprivation In general, a person can survive without oxygen to the brain for 5 to 10 minutes, here is a breakdown: After 1 minute of oxygen deprivation, cells in the brain begin to die, but survival and recovery are possible, especially if appropriate treatment methods are taken.

An article in Archiv Fur Kriminologie states the body can survive for 8 to 21 days without food and water and up to two months if there's access to an adequate water intake. Modern-day hunger strikes have provided insight into starvation.

In most cases, a coma is induced for a few days up to two weeks; induced comas longer than a month are extremely rare.

If you stop eating and drinking, death can occur as early as a few days, though for most people, approximately ten days is the norm. In rare instances, the process can take as long as several weeks. It depends on your age, illness, and nutritional status.

There are no precise answers. In general terms, the human body can go two to three days without water and, it is often said in survival guides, 30 to 40 days without food of any kind. (Many of these guides also discourage people from scavenging for wild plants or shrubs because of the adverse effects these can have.)

In a 1997 editorial in the British Medical Journal, Peel briefly reviewed the available literature regarding human starvation. Generally, it appears as though humans can survive without any food for 30-40 days, as long as they are properly hydrated.

Generally, it appears as though humans can survive without any food for 30-40 days, as long as they are properly hydrated. Severe symptoms of starvation begin around 35-40 days, and as highlighted by the hunger strikers of the Maze Prison in Belfast in the 1980s, death can occur at around 45 to 61 days.

How long can a person go without food? Two weeks or more.

When someone is no longer taking in any fluid, and if he or she is bedridden (and so needs little fluid) then this person may live as little as a few days or as long as a couple of weeks. In the normal dying process people lose their sense of hunger or thirst.

Most people who remain in a vegetative state die within 6 months of the original brain damage. Most of the others live about 2 to 5 years.
