Unlocking the Mystery: What’s a Peg Tube?

A percutaneous endoscopic gastrostomy, commonly known as a PEG tube, is a medical device used to deliver nutrition and hydration to patients who are unable to eat or drink orally. This procedure involves implanting a tube through the abdominal wall into the stomach, allowing for direct delivery of nutrients, medication, or fluids.

When is a PEG Tube Needed?

Patients who are unable to eat or drink by mouth may require a PEG tube to maintain proper nutrition and hydration. There are several reasons why a person may be unable to eat or drink, including:

  • Stroke
  • Cancer
  • Head or neck surgery
  • Neurological disorders
  • Severe gastrointestinal disorders

PEG tubes are often used as a temporary measure for patients who are expected to recover and regain their ability to eat and drink normally. However, in some cases, a PEG tube may be a permanent solution for patients with long-term feeding difficulties.

What is the Procedure for Inserting a PEG Tube?

The procedure for inserting a PEG tube involves:

  1. A gastroenterologist or a surgeon will administer local anesthesia to numb the area where the tube will be inserted.
  2. A small incision is made in the abdomen, and a thin, flexible tube is passed through the mouth and down the esophagus and into the stomach.
  3. The tube is then guided through the incision in the abdomen and attached to a feeding bag or pump.

The entire procedure typically takes between 30 minutes and an hour.

What is the Care and Maintenance of a PEG Tube?

Proper care and maintenance of a PEG tube are critical to avoiding complications and ensuring the tube functions correctly. Some tips for caring for a PEG tube include:

  • Cleaning the skin around the tube daily with soap and water
  • Clamping the tube when not in use to prevent leakage
  • Flushing the tube with water before and after feeding or medication administration
  • Using only liquid medications and avoiding crushing or opening capsules and tablets
  • Changing the feeding bag or pump every 24-48 hours

If you notice any signs of infection or other complications, such as redness, swelling, or discharge around the tube, contact your healthcare provider immediately.

What are the Risks and Complications of a PEG Tube?

While PEG tubes are generally safe and effective, there are some risks and complications that can occur, including:

  • Infection
  • Dislodgement or migration of the tube
  • Blockage of the tube
  • Peritonitis (infection of the lining surrounding the abdominal organs)
  • Bleeding

It is essential to monitor the tube site daily for any signs of infection or other complications and to follow proper care and maintenance guidelines.


PEG tubes are a critical tool in providing nutrition and hydration to patients who are unable to eat or drink orally. While the procedure for inserting a PEG tube is relatively straightforward, proper care and maintenance are necessary to avoid complications and ensure the tube functions correctly.

Common Questions about PEG Tubes

  • What is the difference between a PEG tube and a G tube?
  • A PEG tube is inserted through the skin and into the stomach, while a G-tube is inserted directly into the stomach through an incision in the abdomen.

  • Can a PEG tube be removed?
  • Yes, PEG tubes are often removed once a patient has recovered and can eat and drink normally.

  • Are there any restrictions on what a patient with a PEG tube can eat?
  • Patients with PEG tubes are typically put on a liquid or pureed diet to prevent clogging the tube.

  • How long can a patient have a PEG tube?
  • PEG tubes can be used as a temporary solution, but long-term use is also possible.

  • Are there any activities that patients with PEG tubes should avoid?
  • Patients with PEG tubes should avoid swimming, soaking in tubs, or engaging in activities that could dislodge the tube.
