GORD, lifestyle, acid suppression - and when surgery earns its place.

One in five UK adults get troublesome reflux every week. Most is managed well with lifestyle change and a short course of a proton pump inhibitor. Some needs endoscopy, and a few benefit from an operation.

Key facts

GORD at a glance.

The essentials, in plain English. What it is, who gets it, what UK guidance recommends, and when to seek urgent review.

  • What it is

    Retrograde flow of stomach contents into the oesophagus causing troublesome symptoms or mucosal damage.

  • How common

    Around one in five UK adults experience troublesome reflux symptoms at least weekly.

  • Types

    Erosive oesophagitis, non-erosive reflux disease (NERD), Barrett oesophagus and extra-oesophageal reflux.

  • Key drivers

    Obesity, hiatus hernia, pregnancy, smoking, alcohol and certain medications including NSAIDs and calcium channel blockers.

  • Foundation therapy

    Lifestyle change plus a proton pump inhibitor at full dose for four to eight weeks, then a step-down plan.

  • When to escalate

    Dysphagia, weight loss, GI bleeding, anaemia, or new symptoms over age 55 need urgent upper GI endoscopy per NICE NG12.

Why this guide matters

A stepped plan, not a lifetime of tablets.

GORD is common and usually manageable. The three points below shape everything else on this page.

  • Lifestyle is not a footnote

    Weight loss, meal timing and raising the head of the bed measurably reduce reflux and can lower or remove the need for medication.

  • PPIs are a treatment, not a habit

    A full-dose course for four to eight weeks, then a step-down. Long-term daily use needs a clear indication and review.

  • Endoscopy answers the hard questions

    For alarm features, refractory symptoms or before surgery, upper GI endoscopy and pH-impedance testing change the plan.

How the diagnosis is made

From first symptoms to a clear plan.

The steps a UK GP or gastroenterologist will normally follow, in order, so you know what to expect and why.

  1. 01

    Assessing

    History and red-flag screen

    A careful review of heartburn, regurgitation, cough and any alarm features that would trigger a two-week wait referral.

  2. 02

    Assessing

    Empirical trial of PPI

    For typical symptoms without red flags, a full-dose PPI for four to eight weeks is both treatment and a diagnostic clue.

  3. 03

    Assessing

    Helicobacter pylori test

    Test-and-treat is considered in refractory dyspepsia and in patients requiring long-term acid suppression.

  4. 04

    Confirming

    Upper GI endoscopy (OGD)

    Indicated for red flags, refractory symptoms, Barrett surveillance or before antireflux surgery. See our gastroscopy guide.

  5. 05

    Confirming

    Ambulatory 24-hour pH-impedance

    The gold standard for confirming acid and non-acid reflux, and for correlating symptoms with reflux events.

  6. 06

    Confirming

    High-resolution manometry

    Selective use to exclude motility disorders such as achalasia before surgery or when swallowing is disordered.

  7. 07

    Planning

    Specialist MDT review

    Refractory, complicated or surgical candidates are reviewed by gastroenterology and upper GI surgery together.

Typical timeline: first visit to a settled plan in weeks, endoscopy where indicated within a few weeks more.

Symptoms

What GORD actually feels like.

Classic heartburn and regurgitation, plus the throat, chest and dental clues that reflux is behind less obvious symptoms - and the features that mean it is time to escalate.

  • Heartburn

    A burning retrosternal discomfort, worse after meals and when lying down or bending forwards.

  • Regurgitation

    Effortless return of gastric contents into the mouth or throat, often with a sour or bitter taste.

  • Water brash

    A sudden flood of saliva in response to reflux, sometimes mistaken for excess mucus.

  • Chest pain

    Non-cardiac chest pain from reflux can mimic angina. Cardiac causes must be excluded first.

  • Dysphagia

    Difficulty swallowing can signal stricture, severe oesophagitis or malignancy. See our dysphagia guide.

  • Chronic cough and hoarseness

    Extra-oesophageal reflux can cause a long-standing cough, throat clearing and a rough voice.

  • Dental erosion and halitosis

    Acidic reflux thins tooth enamel and drives unexplained bad breath, particularly on waking.

  • Red flag - dysphagia or weight loss

    New dysphagia, weight loss, bleeding, anaemia or symptoms over age 55 warrant urgent upper GI endoscopy.

Treatment

How GORD is treated in the UK.

Lifestyle first, PPI therapy as the backbone, endoscopy where indicated, and antireflux surgery for the minority who need it.

  • Lifestyle and weight

    Weight loss, raising the head of the bed, smaller evening meals and avoiding late-night eating make a measurable difference.

  • Proton pump inhibitor

    Omeprazole, lansoprazole, pantoprazole, esomeprazole or rabeprazole at full dose for four to eight weeks, then step-down.

  • H2 receptor antagonist

    Famotidine is a useful second-line or add-on option, especially for nocturnal breakthrough symptoms.

  • Alginates and antacids

    Gaviscon-style alginates form a raft on the gastric contents and give quick, on-demand relief.

  • Prokinetic (selective)

    Metoclopramide or domperidone can help in selected cases, with MHRA-guided time limits and monitoring.

  • Laparoscopic fundoplication

    Nissen or Toupet fundoplication remains the gold-standard antireflux operation for refractory or PPI-intolerant disease.

  • LINX and endoscopic options

    LINX magnetic sphincter augmentation, Stretta radiofrequency and TIF are alternatives in carefully selected patients.

  • Barrett surveillance and RFA

    Endoscopic surveillance, radiofrequency ablation, EMR or ESD for dysplastic Barrett oesophagus in a specialist unit.

A quiet reminder

This guide is for information, not medical advice.

Your GP or gastroenterologist knows your history and can tell you which parts apply to you. If in doubt, get seen.

  • NICE CG184. Gastro-oesophageal reflux disease and dyspepsia in adults: investigation and management.

  • NICE NG12. Suspected cancer: recognition and referral (upper GI cancer criteria).

Red flags

When reflux needs urgent attention.

Most GORD is manageable in primary care. These are the situations that are not, and where NICE NG12 or specialist input is needed.

  • Dysphagia

    New or progressive difficulty swallowing needs urgent upper GI endoscopy on a two-week-wait pathway.

  • Unintentional weight loss

    Weight loss with reflux symptoms is a NICE NG12 alarm feature and mandates urgent specialist review.

  • Gastrointestinal bleeding

    Haematemesis, coffee-ground vomiting or melaena is an emergency requiring same-day assessment.

  • Iron-deficiency anaemia

    Unexplained anaemia in a patient with reflux warrants both upper GI and lower GI investigation.

  • New symptoms over age 55

    Fresh dyspepsia or reflux over age 55, especially if persistent, meets criteria for urgent endoscopy.

  • Cardiac chest pain

    Reflux can mimic angina. Any cardiac features need urgent cardiology assessment first.

  • Refractory symptoms on high-dose PPI

    Ongoing symptoms despite optimised PPI therapy deserve endoscopy and ambulatory pH-impedance testing.

  • Barrett oesophagus with dysplasia

    High-grade dysplasia or early adenocarcinoma is treated in a specialist upper GI centre with RFA, EMR or surgery.

  • Aspiration and pulmonary symptoms

    Recurrent aspiration, pneumonia or worsening asthma related to reflux needs joint respiratory and GI input.

Living with it

A treatable condition, with a clear ladder.

Four things that make the biggest difference day to day: weight and posture, meal timing, knowing your personal triggers, and refusing to drift on long-term medication without a review.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits kept up for months do more than a heroic week that does not last.

  1. 01 Routine

    Weight and posture win

    Modest weight loss and raising the head of the bed by 15 to 20 centimetres reduce night-time reflux more than any diet change.

  2. 02 Timing

    Give the stomach three hours

    Finishing meals at least three hours before lying down prevents most nocturnal breakthrough symptoms.

  3. 03 Triggers

    Find your personal list

    Alcohol, coffee, chocolate, spicy food, tomatoes and citrus affect people differently. Track what actually matters for you.

  4. 04 Escalate

    Don’t drift on long-term PPIs

    If you need daily acid suppression for months, revisit the diagnosis, review medication and consider endoscopy or surgery.

Frequently asked

Everything we get asked about GORD.

Quick answers on PPIs, endoscopy, Barrett oesophagus and antireflux surgery.

  • What is gastro-oesophageal reflux disease (GORD)?

    GORD is the retrograde flow of stomach contents into the oesophagus in a way that causes troublesome symptoms or mucosal complications. It ranges from non-erosive reflux disease with a normal endoscopy through erosive oesophagitis to Barrett oesophagus and, rarely, oesophageal adenocarcinoma.

  • When should I see a doctor about heartburn?

    See a clinician if reflux is frequent, wakes you at night, needs regular over-the-counter treatment or fails to settle after a four-to-eight-week PPI trial. Seek urgent review for dysphagia, weight loss, bleeding, anaemia or new symptoms over age 55.

  • Do I need an endoscopy?

    Not everyone. Typical symptoms without red flags are usually managed empirically. Upper GI endoscopy is offered for alarm features, refractory disease, Barrett surveillance and before antireflux surgery. Our gastroscopy guide explains what to expect.

  • How long should I stay on a proton pump inhibitor?

    NICE recommends a full-dose PPI for four to eight weeks, then a step-down to the lowest effective dose or on-demand use. Long-term daily PPIs are appropriate for erosive oesophagitis, Barrett oesophagus and after complications, with periodic review.

  • Are proton pump inhibitors safe long-term?

    For most patients the balance of benefit is favourable, but long-term use has been associated with small increases in fracture risk, kidney disease, hypomagnesaemia and Clostridioides difficile infection. Regular review, the lowest effective dose and a clear indication are the pillars of safe long-term prescribing.

  • When is surgery for reflux appropriate?

    Antireflux surgery, most commonly laparoscopic Nissen or Toupet fundoplication, is considered for refractory symptoms, PPI intolerance, large hiatus hernia or a strong patient preference to avoid lifelong medication. LINX and endoscopic options such as Stretta or TIF are alternatives in selected cases.
