Every child with a gastrostomy tube will experience complications. Not some. All.

This isn't a reflection of how well you're managing care at home. It's the reality of tube feeding. The tube is a foreign object passing through the abdominal wall into the stomach. Complications are built into the system.

Your job isn't to prevent all complications. It's to know which ones you can handle at home, which ones need a call to the provider, and which ones require immediate emergency care.

The Most Common Complications

All individuals with intellectual disability who are tube-fed report complications. The most frequent ones are nausea and vomiting, constipation, diarrhea, stoma site infections or granulation tissue, formula leakage around the tube, tube dislodgement, and aspiration.

Some of these you can manage with adjustments to feeding protocol. Some require medical intervention. And some require you to grab your emergency kit and head to the ER.

The difference is specificity: knowing what you're looking at, what causes it, and what the appropriate response is.

Nausea and Vomiting

Nausea and vomiting during or after tube feeds are common. The usual culprits are feeding rate, formula temperature, or positioning.

If you're running bolus feeds too quickly, the stomach doesn't have time to accommodate the volume. Slowing the rate often fixes it. Some children tolerate continuous feeds better than bolus feeds because the stomach never has to handle a large volume at once.

Positioning matters. Keep your child's head elevated 30 to 45 degrees during the feed and for at least 30 minutes after. Gravity helps. Lying flat increases the chance of reflux and vomiting.

Formula temperature can trigger nausea in some kids. Room temperature is usually better tolerated than cold formula straight from the fridge.

If vomiting is persistent despite these adjustments, or if there's blood in the vomit, call your provider. Blood means something more than rate or positioning is going on.

Constipation

Constipation is very common in tube-fed patients. The reasons vary: limited or no oral intake, certain formulas, medications, or underlying conditions that affect motility.

Fiber-containing formulas can help. If your child is on a standard formula without fiber, ask the provider or dietitian whether switching makes sense. Some children benefit from added fiber supplements.

Adequate free water alongside feeds is essential. Many tube-fed children don't get enough water flushes, and that contributes to hard stools.

If constipation is severe or persistent, your provider may recommend a stool softener or other intervention. Don't wait until your child is impacted. Address it early.

Diarrhea

Diarrhea in tube-fed children often comes down to formula concentration, feeding rate changes, or antibiotic use.

If you recently increased the concentration of the formula or the volume too quickly, the gut may not be able to keep up. Slowing down the progression usually resolves it.

Antibiotics disrupt normal gut flora and frequently cause diarrhea. Some families use probiotics during antibiotic courses, though the evidence is mixed. Talk to your provider before adding anything.

Persistent diarrhea can lead to dehydration and electrolyte imbalances. If it lasts more than a day or two, or if your child shows signs of dehydration like dry mouth, decreased urine output, or lethargy, call your provider.

Stoma Site Infection

The stoma is where the tube enters the body. Redness, warmth, odor, or drainage from the site are early signs of infection.

Daily cleaning is your first line of defense. Wash the site with soap and water. Not hydrogen peroxide. Hydrogen peroxide delays healing and irritates tissue. Soap and water is what you need.

Turn the tube 360 degrees daily. This prevents the formation of granulation tissue and keeps the tube from adhering to the stoma tract.

Check the external bumper or disk. It should be snug against the skin but not too tight. If it's pressing into the skin, you'll see indentation or redness. That pressure can cause breakdown. If it's too loose, formula can leak and irritate the skin.

If you see purulent drainage, fever, or spreading redness around the stoma, call your provider. These are signs of infection that may require antibiotics.

Granulation Tissue

Granulation tissue is pink or red, beefy-looking tissue that forms around the stoma. It's the body's response to irritation or moisture. It's common, not dangerous, but it can bleed easily and cause discharge.

Keeping the site clean and dry reduces it. Turning the tube daily helps. If granulation tissue becomes problematic, your provider can treat it with silver nitrate or prescribe a steroid cream. Don't try to remove it yourself.

Formula Leakage

Leakage around the tube happens. Sometimes it's because the balloon isn't holding the correct volume of water, if your tube has one. Sometimes it's because the stoma tract has stretched.

Check the balloon water volume regularly. Your tube should have a specified volume, usually 3 to 5 mL for a pediatric G-tube. If the balloon is underinflated, the tube can migrate and formula can leak.

If leakage is persistent and the balloon volume is correct, the stoma tract may have widened. This can happen over time. Your provider may need to upsize the tube.

Leakage irritates the skin. Clean the area gently and keep it as dry as possible. A barrier cream can protect the skin from further breakdown.

Tube Dislodgement

Tubes come out. It happens to every family at some point.

If the tube comes out, stay calm and act quickly. Know your tube type, the balloon water volume, and how old the stoma is.

If the stoma is less than 6 months old, it can close within hours. This is an emergency. You need to get the tube replaced or a placeholder inserted immediately. Go to the ER if you can't reach your provider or if your provider directs you to do so.

If the stoma is well-established, older than 6 months, you have more time, but not unlimited time. Most providers recommend getting the tube replaced within 4 to 6 hours to prevent the tract from narrowing.

Your emergency kit should include a replacement tube, same size or one size smaller, and water-soluble lubricant. If you're trained to replace the tube, you can do it at home. If not, head to the ER or your provider's office.

Aspiration Risk

Aspiration is when formula or stomach contents enter the lungs instead of staying in the digestive tract. It can cause pneumonia and respiratory distress.

Elevating the head during and after feeds reduces risk. Avoid rapid feed rates. If your child has a history of reflux or aspiration, your provider may recommend checking gastric residuals before feeds, though this practice is debated.

Watch for signs of aspiration: coughing during or after feeds, increased secretions, respiratory distress, or recurrent lung infections. If you see these, call your provider immediately.

If your child has a known aspiration event, meaning you see formula come out of the mouth or nose during a feed followed by choking or coughing, go to the ER. Aspiration pneumonia is serious.

When to Call vs When to Go to the ER

Some situations are urgent. Some are emergencies. Knowing the difference keeps you from underreacting or overreacting.

Call your provider if you see fever along with stoma site infection, vomiting that persists despite adjustments, diarrhea lasting more than two days, or signs of dehydration.

Go to the ER if the tube is completely out and the stoma is less than 6 months old, if there's blood in the vomit, if your child has an aspiration event with respiratory distress, or if there are signs of severe infection: high fever, spreading redness, lethargy.

You know your child. If something feels wrong, trust that. It's better to make the call and have it be nothing than to wait and miss something serious.

You're Managing a Medical Device at Home

Tube feeding is medical care. You're managing a medical device that crosses the abdominal wall and delivers nutrition directly into the stomach. Complications aren't a sign that you're doing it wrong. They're part of the territory.

The goal is competence, not perfection. Know what normal looks like for your child. Know the prevention steps. Know when to troubleshoot at home and when to escalate. That's the skillset that keeps your child safe and reduces unnecessary ER visits.

You're not just a parent. You're a medical care provider in your own home, and the more specific your knowledge, the more capable you are.
