Feeding tubes are placed in different ways depending on the type, but the two most common approaches are threading a thin tube through the nose down to the stomach (done at the bedside in minutes) or creating a small opening through the skin of the abdomen directly into the stomach (done as a short procedure with sedation). The method your medical team chooses depends on how long you’ll need the tube and your overall health.
Types of Feeding Tubes
There are four main types, and the placement method flows directly from where the tube needs to go. Nasogastric (NG) tubes run from the nose to the stomach. Nasojejunal (NJ) tubes also enter through the nose but extend further, reaching the second part of the small intestine. Both are considered temporary, typically used for days to weeks.
For longer-term feeding, tubes go directly through the abdominal wall. A gastrostomy tube (G-tube) enters the stomach, and a jejunostomy tube (J-tube) enters the small intestine. These are placed through a minor procedure and can stay in for months or years.
How a Nasal Feeding Tube Is Placed
Nasal tubes are inserted at the bedside without sedation. You sit upright with the bed raised to at least 30 degrees and your head in a neutral position. A nurse or clinician measures the tube against your body to estimate how far it needs to go, then lubricates the first two to three inches of the tip with a water-soluble gel.
The tube slides into one nostril and advances toward the back of the throat. This is the part most people find uncomfortable. Once the tube reaches the back of your throat, you’ll be asked to tuck your chin down toward your chest and swallow. Swallowing helps guide the tube into the esophagus instead of the airway. Some clinicians offer sips of water through a straw to make swallowing easier. The tube is then advanced the remaining distance into the stomach (or small intestine for an NJ tube).
The whole process takes only a few minutes, though it can feel longer. You may gag or tear up, which is normal. Once in place, the tube is taped to the side of your nose to keep it from shifting.
Confirming the Tube Is in the Right Place
Before any feeding starts, the team needs to verify the tube landed in the stomach and not in the lungs. The gold standard is an X-ray. A secondary bedside method involves drawing a small amount of fluid from the tube and testing its acidity: a pH of 5 or lower reliably indicates stomach contents. If either test is unclear, an X-ray is repeated before feeding begins.
How a PEG Tube Is Placed
The most common long-term feeding tube is a PEG tube, short for percutaneous endoscopic gastrostomy. “Percutaneous” means through the skin, and “endoscopic” means a small camera guides the process. The procedure typically takes 15 to 30 minutes.
You’ll receive sedation, ranging from conscious sedation (relaxed but not fully asleep) to deeper sedation, along with a local anesthetic injected into the skin of your abdomen. In some centers, particularly for patients with neuromuscular conditions, the procedure can be done with local anesthesia alone, no sedation at all.
The clinician passes a thin, flexible camera called an endoscope through your mouth, down the esophagus, and into the stomach. The camera serves two purposes: it lights up the stomach wall so the team can see exactly where to place the tube from the outside, and it lets them watch the tube enter the stomach in real time. A small skin incision, roughly a centimeter wide, is made on the abdomen. A needle passes through the incision into the stomach, and then a guidewire follows.
The most commonly used method, called the Ponsky or “pull” technique, works like this: a thin thread is passed through the needle into the stomach, grabbed by a small snare fed through the endoscope, and pulled back up through the mouth. The feeding tube is attached to this thread and pulled in reverse, traveling from the mouth down through the esophagus, into the stomach, and out through the abdominal wall. The tube has an internal bumper that sits against the inside of the stomach wall, holding it in place. The camera is reinserted briefly to confirm the tube is positioned correctly.
Laparoscopic and Surgical Placement
PEG placement requires the ability to pass a camera through the esophagus, which isn’t always possible. Patients with head, neck, or esophageal cancers, or those with prior abdominal surgeries that distort the anatomy, may need a different approach. In these cases, surgeons can place a G-tube laparoscopically under general anesthesia.
This involves one or two small incisions. A tiny camera is inserted near the belly button, and carbon dioxide gas inflates the abdomen to create a working space. The surgeon identifies the best spot on the stomach, pulls a small portion of the stomach wall up to the abdominal surface through the second incision, stitches it in place, and inserts the feeding tube through a small opening. The procedure is more involved than a PEG but still minimally invasive, and it gives the surgeon direct visualization of the surrounding organs.
How to Prepare Before Placement
For any procedure involving sedation or anesthesia, you’ll need to fast beforehand. Standard guidelines call for no solid food for at least 6 hours, no non-clear liquids for 4 hours, and only small amounts of clear liquids (water, apple juice, black coffee) up to 2 hours before the procedure. If you’ve eaten a heavy meal, the wait may extend to 10 hours. Your care team will give you specific instructions about which medications to take or skip on the morning of the procedure.
Nasal tubes placed at the bedside generally don’t require fasting, since no sedation is involved.
What Recovery Looks Like
After a nasal tube, there’s essentially no recovery period. You may have a sore throat and mild nasal irritation for a day or two. Feeding can start as soon as placement is confirmed by X-ray or pH testing.
After a PEG or surgical G-tube, the abdominal site typically heals within 5 to 7 days. You may feel soreness around the incision for the first few days. Research involving over 400 patients has shown that feeding can safely begin within 4 hours of PEG placement, though some physicians still prefer to wait up to 24 hours. During that waiting period, fluids are given intravenously.
You’ll receive instructions on how to clean the skin around the tube, how to flush the tube with water to prevent clogging, and how to recognize signs that something isn’t right at the site.
Risks and Complications
Nasal tubes carry the risk of irritation to the nasal passages and throat, sinus infections, and aspiration, which happens when stomach contents or formula enter the lungs. Aspiration risk is present with all types of feeding tubes and is one reason head elevation during and after feeding matters.
For PEG and surgical tubes, the most common complication is infection at the skin site where the tube enters the abdomen, occurring in roughly 4% to 30% of procedures. Most of these are minor and resolve with wound care or antibiotics. Serious complications requiring additional intervention, such as leakage into the abdominal cavity or injury to nearby organs, occur in 0.4% to 4.4% of cases.
The risk profile is generally low, which is why PEG placement remains one of the most frequently performed procedures for patients who need long-term nutritional support.
