Tube feeding in children

Nasogastric (NG) tubes go through the nose into the stomach. They're usually short-term - weeks to a few months - and are often the first step. They can be replaced at home if they come out, and they don't require surgery. The downsides: they're visible, can be uncomfortable, and need replacing regularly.

Gastrostomy tubes (PEG or button) are placed directly through the abdominal wall into the stomach, usually under general anaesthetic. They're the standard for long-term tube feeding. Once the initial tract has healed (six to eight weeks), the tube can often be changed to a low-profile 'button' device that sits flat against the skin and is easier to manage day-to-day.

Jejunostomy tubes deliver feed further down, into the small intestine. They're used when the stomach doesn't tolerate feeds well - typically in children with severe reflux, gastroparesis, or specific surgical histories. Jejunal feeds need to be given more slowly and continuously, which affects the daily routine.

Blended diets - real food blended to a smooth consistency and given through the tube - have become increasingly popular and increasingly accepted clinically, with organisations such as the BDA now providing guidance on their safe use. The evidence base is growing, and evidence suggests blended diets may improve tolerance, and some studies indicate potential benefits for reflux and stool consistency, and a sense of normalcy that comes from their child eating 'family food'.

Done with proper nutritional planning and food safety, blended diets can work very well. The important caveats: the blender needs to produce a genuinely smooth consistency (commercial high-speed blenders are worth the investment), hygiene matters because the food is bypassing the mouth's defences, and nutritional adequacy needs monitoring - it's easy to assume a 'normal diet blended up' is nutritionally complete when it may not be.

I help families transition to blended diets safely. We plan the recipes to meet the child's specific nutritional needs, establish food safety protocols, and monitor growth and tolerance through the transition. Some families move to fully blended diets; others use a combination of commercial feeds and blended food. Both approaches are valid.

Many tube-fed children also take some food by mouth. The tube supplements rather than replaces oral intake, and as the NHS explains, maintaining oral feeding skills where safe to do so is usually an important goal. Some children are working toward tube weaning - reducing tube dependency and increasing oral intake over time.

The balance between tube feeds and oral intake needs careful management. Too much tube feed and the child isn't hungry enough to eat. Too little and nutrition suffers. I adjust feed volumes, timing and delivery speed to create favourable conditions for oral feeding while maintaining adequate overall nutrition.

Tube weaning - the process of reducing and eventually stopping tube feeds - is possible for some children but needs to be carefully planned and monitored. Weight, growth, hydration and overall wellbeing all need tracking throughout. It's a process that takes weeks to months and shouldn't be rushed.
