If a hospitalized person cannot eat refuses a feeding tube how long can he live?

If a hospitalized person cannot eat and refuses a feeding tube, their survival time can vary significantly based on several factors, including their overall health, hydration, and underlying medical conditions. Generally, a person can survive without food for about 1 to 2 months, depending on body fat and muscle reserves, but survival without water is typically only a few days to a week. It's essential to provide supportive care, including hydration, to extend life and comfort. Ultimately, individual circumstances will greatly influence any specific timeline.
