Growth Challenges are Common for People with Cystic Fibrosis



Cystic fibrosis (CF) affects many parts of the body. As part of their disease, children with CF commonly have trouble gaining weight. Trouble gaining weight can also slow down their height gain, which may prevent them from meeting their height potential and affect their lung development.

Children with CF need to consume more calories than children without CF. This is because they require increased energy to fight lung infections, to compensate for their difficulties absorbing nutrients, and to keep their lungs and body strong to feel their best.

Checking your child’s growth at each appointment is important to make sure their trajectory over time is closer to the 50th percentile. Traditionally, being close to or above the 50th percentile has been shown to support long-term health and be associated with improved outcomes for people with CF.

If your child with CF is having a difficult time eating enough to help them grow or the effort needed to help them grow is becoming very challenging for your family,  your CF care team may bring up the option of tube feeding, including a gastrostomy tube, or G-tube for short.

How to Use This Decision Aid

Having a G-tube can be a healthy way for your child with CF to get the calories and nutrients they need to grow.

Families typically have many questions and concerns about G-tubes and the potential impact of a G-tube on their child as well as their family. Caregivers often report it is a difficult decision with many pros and cons to consider.

Decision aids are tools to help people who are considering a potential health decision that has benefits as well as risks and complications, such as a G-tube.

This decision aid was created with support from the Cystic Fibrosis Foundation and with help from caregivers of children with CF and CF specialists to to help you feel more informed about G-tubes and help you make the best decision for your child’s health and your family.

This decision aid will have 3 modules. At the end of each module, you will be able to download your responses and questions to help guide conversations with your care team about the best decision for your child and family.

Under Construction

Children >11 years will be important decision-makers when considering a G-tube. Currently, this tool only focuses on caregivers of young children with CF.

We know it will be important to have a section for older kids and teenagers to learn about G-tubes, to provide guidance on how to have discussions about G-tubes with older kids, as well as information for older kids and teenagers about caring for their G-tube and concerns about body image.

Stay tuned for more age-appropriate information about G-tube decision-making soon!

If you are interested in learning more generally about G-tubes in CF care, this tool will still have useful information to consider and discuss with your care team.

Tube Feeding Basics

Tube feeding is when a soft tube is used to provide nutrition directly into the stomach. 

Typically, the same supplements/formulas that your CF care team has recommended your child drink to increase their caloric intake can go through the tube. Families can also give certain blended foods, fluids, and most medications through the tube.​ 

Tube feeding typically does not replace eating by mouth. Children can eat as much as they want and also receive extra nutrition to help them grow, develop, and thrive.

Tube feeding, such as a G-tube, can be temporary. G-tubes may be used for months to years and can be easily removed when weight challenges resolve.

Why are tube feedings used in CF​ care?

Children with CF have calorie needs that are 1.5 to 2 times higher than those of people without CF. It can be hard for a child to eat that amount of food each day and can also be stressful for families.

Despite caregivers' best efforts and trying every option recommended by their CF care team, CF can make it hard for some children to grow. Tube feedings are recommended by the Cystic Fibrosis Foundation (CFF) because they are a tool that can help children grow and feel their best.

According to the CFF Patient Registry, nearly 1 in 5 children with CF will use a form of tube feeding by age 10​. This means many families consider this decision for their child with CF.​

What are the options for tube feeding in CF?

GASTROSTOMY TUBE (G-Tube)
- A soft flexible tube with a plastic button at the skin that enters the stomach from an incision in the abdomen
- Requires a procedure with anesthesia to place​
- Less visible because usually hidden by shirt
- Typically a longer term option, but can easily be removed when no longer needed
- There will be a scar when it is removed

Field is required!
Field is required!

NASOGASTRIC TUBE (NG)
- A long, thin, flexible tube that goes in the nose and down the throat so the tip is in the stomach.
- The end of the tube is taped to the cheek to hold it in place, though young children (toddler/preschoolers) can still pull the tube out (and commonly do).
- Less invasive because surgery is not required
- NG tube placement may be uncomfortable at first but gets easier with practice. Caregivers and older children/adults can be taught how to insert the NG tube at home themselves and to confirm proper placement
- It can be inserted at night and removed during the day for school. Visible on the face only while it is in place
- NG feeding can be trialed for a period of time a child gets a G-tube ​

How do tube feedings fit into your child's day?

There are two common methods of tube feeding – continuous infusion overnight and bolus feeds throughout the day. Talk with your CF dietitian to determine which schedule would work best for your family. This will include picking the right nutrition option for your child, including choosing between commercial formulas or blenderized diets.

Continuous feeding: These feedings are typically given over a longer period of time, such as overnight while your child is asleep. These feeds are given by a feeding pump. This option is most common for children and adults who eat well during the day. Getting extra calories during the night will likely delay your child’s appetite for breakfast by several hours.

Bolus feeding: These feedings are typically given over 5-40 minutes, by gravity or on a feeding pump, about 3 times per day, depending on how much your child eats or drinks at mealtimes. Bolus feeds can be given as part of a meal after your child eats what they want. Children who eat small amounts by mouth will benefit from getting a bolus feeding at mealtimes to provide good nutrition while they are awake.
