Neonatal gastro-oesophageal reflux and aspiration
Also known as Neonatal gastro-oesophageal reflux · Neonatal GOR/GORD · Infant reflux and posseting · Reflux-associated aspiration in the newborn · Neonatal reflux oesophagitis
Fellowship guide to neonatal gastro-oesophageal reflux and aspiration — how to tell physiologic posseting from disease, the immature lower-oesophageal-sphincter pathophysiology, the conservative-first stepwise management that protects infants from unnecessary acid suppression, and the red flags that turn a happy spitter into a sick child.

Red flags
- Bilious (green) vomiting is never reflux — it is malrotation or intestinal obstruction until proven otherwise and demands urgent imaging
- Forceful projectile vomiting in a neonate is pyloric stenosis or obstruction, not GORD; palpate for a pyloric tumour and check the chloride
- Reflux with failure to thrive, haematemesis, or recurrent aspiration is disease, not physiologic reflux, and warrants investigation and treatment
- Acid suppression in preterm infants without proven oesophagitis is not benign — it is linked to infection, NEC, and fracture risk and does not improve apnoea
- Thickened feeds carry a small risk of necrotising enterocolitis in preterm infants and must not be prescribed reflexively for every posset
- A 'reflux' diagnosis that delays a septic or surgical work-up in a vomiting neonate is the dangerous error — exclude the mimics first

Overview & Definition
Sit with any neonatal nurse for a shift and you will hear the word 'reflux' a dozen times — each posset, each desaturation, each irritable feed attracts the label, and most of time label is wrong. The discipline this topic teaches is restraint: the ability to tell the common, harmless, self-limiting reflux of the thriving newborn from the disease that harms, and to refuse the reflex of reaching for an acid-suppressing drug that the evidence does not support. [1]
Gastro-oesophageal reflux, or GOR, is the effortless retrograde movement of gastric contents into the oesophagus, with or without regurgitation into the mouth. In infants it is the norm, not the exception — a developmental phenomenon of an immature anti-reflux barrier that resolves spontaneously as solid food and sitting take over. The term GORD, gastro-oesophageal reflux disease, is reserved for reflux that produces complications, and the distinction between the two is the single most important judgement you will make at the cot-side. [1]
The definitions examiners expect are precise. Regurgitation is the visible return of food into the mouth. Posseting is the small, effortless bringing up of milk. Vomiting, by contrast, is forceful and involves muscular effort — and a forceful or projectile vomit in a neonate is not reflux but a surgical symptom until proven otherwise. Aspiration is the entry of refluxed material into the airway, and it is the complication you most fear because it converts a benign condition into a threat to the lung. [4]
