Dying from dehydration is generally not uncomfortable once the initial feelings of thirst subside. 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.

Without any fluids (either as sips, ice chips or intravenously) people with a complete bowel obstruction most often survive a week or two. Sometimes it's only a few days, sometimes as long as three weeks. With fluids, survival time may be extended by a few weeks or even a month or two.

Eliminating food and water intake for a significant period of time is also known as starvation. Your body can be subject to starvation after a day or two without food or water. At that time, the body starts functioning differently to reduce the amount of energy it burns. Eventually, starvation leads to death.

We can't live on air and sunshine alone. The human body needs food and water to survive. A human can go for more than three weeks without food — Mahatma Gandhi survived 21 days of complete starvation — but water is a different story.

Most comas don't last more than two to 4 weeks. Recovery is usually gradual, with patients becoming more and more aware over time. They may be awake and alert for only a few minutes the first day, but gradually stay awake for longer and longer periods.

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.
