What exactly is it?

You may develop a condition that prevents you from safely eating or drinking, or receiving the necessary nutrition to stay alive. This may be a temporary condition from an accident or condition that affects the throat or a permanent condition like brain damage or dementia. Feeding tubes are narrow tubes that carry liquid nutrition to the stomach. If they are being used for days or weeks, they can be inserted into the nose, down the throat, and into the stomach. But if feeding tubes are needed for more than two weeks, it will usually require surgery for a tube to be placed in the wall of the stomach.
