Are feeding tubes permanent?

Surgical tubes are more long lasting than nasal tubes, but no. The tube itself must be replaced periodically, and both surgical tubes and nasal tubes can be removed at any point. With a surgical tube, once the tube itself is removed, the stoma will close.

If a feeding tube goes past your stomach, do you still absorb nutrition?

Yes. Tubes that bypass the stomach (ND, NJ, J tubes) often go into the small intestine, which still absorbs. There are certain medications that must be taken into the stomach, but even the majority of medications can be absorbed in the small intestine.

Can you still eat with a feeding tube?

This is a commonly asked questions A feeding tube does not prevent an individual from eating. However, the disorder they may be receiving the feeding tube for might.

What is TPN and PPN?

These are different forms of intravenous nutrition, for individuals who for whatever reason cannot tolerate enteral (into the digestive tract) feeds. TPN stands for total parenteral nutrition, and is done through a central line, such as a port, PICC line, or Hickman. PPN is peripheral parenteral nutrition, which can be done through a peripheral vein. Individuals can rely on TPN completely, versus PPN cannot cover all the nutrition. Parenteral nutrition includes electrolytes, minerals, glucose, and fats. PPN is not preferred for long periods of time, and both mixtures are caustic on the veins. TPN contains higher concentrations of nutrients. You can read more about the difference here.

The risks of TPN can include liver damage, complications related to central lines (like infections or clots), glucose abnormalities, gallbladder complications, and others. Because of this, TPN is often considered a last resort.

What is the difference between TPN and enteral feeds?

TPN goes directly to the bloodstream, bypassing the digestive tract entirely. Enteral feeds go into the digestive tract. Sometimes patients will be on a mixture of TPN and enteral feeds.
