Reflux in babies
Gastroesophageal reflux (GOR), also known as regurgitation or posseting, is the passage of gastric contents into the oesophagus. It occurs widely in healthy newborns and infants and is considered normal.15 Incidence of reflux peaks at around 3 months of age. In most cases it resolves without intervention by 6–12 months, coinciding with the maturation of the oesophageal sphincter and the ability to sit upright.16 As long as there are no other symptoms and baby is growing well and seems happy, parents should be reassured that reflux isn’t a major concern.
When could reflux be a sign of something more serious?
Babies with gastroesophageal reflux disease (GORD) experience more troublesome, severe, or long lasting symptoms in addition to reflux, such as poor weight gain and distressed behaviour.17
Advice to parents for managing reflux18
To help with reflux, parents can be advised to try the following:
- Feed in an upright position and hold the baby upright for 20–30 minutes after a feed
- Give smaller, more frequent feeds
- Formula-fed babies should be winded every 2 to 3 minutes during feeding; it should also be ensured the hole in the teat isn’t too big or too small. Parents could consider a trial of an anti-reflux formula.
Parents should be reassured that it is common for babies to bring up milk. However, they should be advised to see their GP or health visitor or return to the surgery if the baby has frequent reflux, is irritable during or after feeds (e.g. arching their back and crying), regularly vomits large amounts up to 2 hours after feeding and starts to fuss or refuse feeds, but accepts a dummy.

Recommendations for the management of GOR
The following are appropriate for babies whose symptoms do not indicate the need for early referral:17
- Reassure parents that symptoms are likely to improve over time
- In clearly overfed babies, advise restriction of feed volume
- In bottle-fed infants with frequent regurgitation which causes distress, use the following stepped-care approach:19
1. Review the feeding history
2. Reduce the feed volumes only if excessive for the infant's weight
3. Suggest smaller, more frequent feeds (while maintaining an appropriate total daily amount of formula)
4. Offer a trial of thickened formula, as advised by NICE
5. If unsuccessful, stop thickened formula and offer alginate* therapy for a trial period of 12 weeks. If the alginate therapy is successful continue with it, but try stopping it at intervals to see if the infant has recovered
- If symptoms remain troublesome, refer the child to a paediatrician
* Do not use in children at risk of dehydration or intestinal obstruction, in those already consuming thickened feeds, in preterm infants, or those with renal impairment or congestive cardiac failure
Guideline recommendations regarding formulas
The European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the National Institute for Health and Care Excellence (NICE) recommend parental reassurance and education when trying to help resolve reflux.17,19
They also recommend trialling a thickened formula for uncomplicated GOR in formula-fed infants.19
Children under 6 months of age can digest starch, a carbohydrate that is used as a thickening agent in certain infant formulas.
SMA PRO Anti-Reflux is thickened with potato starch to offer optimal viscosity in conjunction with high digestibility. This viscosity contributes to the non-reflux of the bolus into the oesophagus. Starch thickened formulas have proven efficacy in reducing the number of daily regurgitation episodes.20-22
SMA® PRO Anti-Reflux is designed for the dietary management of babies with significant reflux. SMA PRO Anti-Reflux contains a unique combination of easily digestible starch and partially hydrolysed, 100% whey protein.
