GORD in children
Exam Tips
- Differentiate GOR vs GORD: regurgitation alone in a thriving infant is usually physiological; troublesome symptoms or complications suggest disease.
- In OSCE history, always ask timing of onset: new vomiting after 6 months or persistence after 1 year should trigger search for alternative diagnoses.
- Red flags to state explicitly: bilious vomiting, GI bleeding, forceful/projectile vomiting, dehydration, fever/systemic illness, severe faltering growth, or neurological signs.
- Management marks are gained by sequencing: feeding/lifestyle optimisation first, short medication trial only if indicated, then reassess and deprescribe if ineffective.
- Name safety cautions: avoid routine prokinetics (adverse effects), use PPIs for clear indications with review, and consider aspiration risk in neurodisabled children.
- For revision diagrams, see the standard paediatric GI figures illustrating transient LOS relaxation and infant anatomical predisposition to reflux.
Definition
Gastro-oesophageal reflux (GOR) in children is the retrograde passage of gastric contents into the oesophagus, which is often physiological in infants when it is not causing distress or harm. Gastro-oesophageal reflux disease (GORD) is diagnosed when reflux leads to troublesome symptoms (such as pain, feeding difficulty, or marked irritability) and/or complications including oesophagitis, aspiration events, or faltering growth.
Pathophysiology
Paediatric reflux is primarily driven by transient lower oesophageal sphincter (LOS) relaxations, allowing gastric contents to move proximally. Infants are predisposed because of a short oesophagus, relatively short/less effective LOS, frequent liquid high-volume feeds, delayed gastric emptying, and prolonged recumbency. Repeated acid (and sometimes non-acid) exposure can inflame the oesophageal mucosa, causing pain, feed aversion, and oesophagitis; extra-oesophageal symptoms (cough, wheeze, hoarseness) may occur via microaspiration or vagally mediated reflex pathways. With maturation (longer oesophagus, improved LOS tone, weaning to solids, upright posture), physiological reflux usually improves.
Risk Factors
- Preterm birth
- Parental history of reflux/heartburn
- Obesity
- Hiatus hernia
- Repaired congenital diaphragmatic hernia
- Repaired oesophageal atresia
- Neurodisability (for example cerebral palsy) or genetic syndromes (for example Down syndrome)
- Chronic respiratory disease (for example asthma, cystic fibrosis)
Clinical Features
Symptoms
- Visible regurgitation/posseting (often effortless in infants)
- Irritability or distress, especially during/after feeds
- Excessive crying, feed refusal, gagging, or choking
- Back arching/posturing; episodic torticollis may suggest Sandifer syndrome
- Chronic cough or hoarseness
- Recurrent vomiting with poor weight gain/faltering growth
- In older children: heartburn, retrosternal pain, epigastric pain
Signs
- Often normal examination in uncomplicated reflux
- Faltering weight centiles or poor growth trajectory
- Signs of dehydration if significant vomiting
- Dental enamel erosion (especially in severe/chronic disease)
- Respiratory signs (wheeze, crackles, chronic cough) in possible extra-oesophageal disease
- Abdominal distension/tenderness or palpable mass suggests alternative diagnosis
Investigations
Management
Lifestyle Modifications
- Reassure if thriving and symptoms are mild; explain natural history (usually self-limiting in infancy)
- Detailed feeding review: avoid overfeeding, optimise feed volume/frequency, check formula preparation
- Trial thickened feeds in bottle-fed infants with troublesome regurgitation
- Continue breastfeeding where possible; involve feeding support/health visitor
- Keep infants smoke-free; avoid seated devices that increase intra-abdominal pressure after feeds
- Urgent referral if red flags (bilious vomiting, haematemesis, severe dehydration, systemic illness, neurological signs)
Pharmacological Treatment
Alginate (infants with persistent troublesome reflux despite feeding optimisation)
- Gaviscon Infant: under 4.5 kg, 1 sachet per feed; 4.5 kg and above, 2 sachets per feed (maximum 6 times daily)
Mix exactly as product instructions; review response after a short trial. Do not combine routinely with feed thickeners unless specialist advice. Watch for constipation and sodium load in prolonged use.
Proton pump inhibitor (suspected reflux-related oesophagitis or persistent pain-related symptoms)
- Omeprazole oral: 1 month-11 years typically 700 micrograms/kg once daily initially (dose adjusted by age/weight and response; usual maximum up to 20-40 mg/day depending on age/size)
- Lansoprazole oral: 1-11 years typically 15 mg once daily if under 30 kg, 30 mg once daily if 30 kg or above; 12-17 years 15-30 mg once daily
Use a time-limited trial (commonly 4 weeks) and step down/stop if no clear benefit. Safety: increased risk of GI and respiratory infections, possible hypomagnesaemia with prolonged use, and rebound acid hypersecretion on abrupt long-term cessation.
H2-receptor antagonist (alternative when PPI not suitable or tolerated)
- Famotidine (specialist/BNFc weight-based dosing, commonly divided twice daily)
Less potent acid suppression than PPIs and tachyphylaxis can occur. Adjust in renal impairment; check for drug interactions and sedation/headache effects.
Surgical / Interventional
- Fundoplication may be considered in severe, confirmed, treatment-refractory GORD or recurrent aspiration, usually after multidisciplinary specialist assessment
- Address contributory anatomical pathology where present (for example large hiatus hernia repair)
Complications
- Reflux oesophagitis
- Oesophageal stricture
- Recurrent aspiration pneumonia
- Recurrent otitis media
- Dental erosion
- Iron deficiency anaemia
- Faltering growth
- Rarely apnoea or apparent life-threatening events
- Family stress and impaired parent-infant feeding interaction
Prognosis
Prognosis is generally good in infancy: symptoms usually start before 8 weeks and resolve by 12 months in most infants (around 90%). Persistence beyond infancy, onset after 6 months, significant comorbidity (for example neurodisability), or early need for acid suppression is associated with greater risk of ongoing symptoms and complications, so closer follow-up is needed.
