Quick answer

What is Acid reflux & GORD?

Acid reflux happens when stomach contents, including acid, flow back up into the oesophagus (the gullet). The valve-like muscle at the top of the stomach normally keeps this from happening, but if it relaxes too easily, acid escapes upwards and irritates the sensitive lining.

  • How it is treated: Treatment follows a step-up, step-down principle: start with the simplest measures and add stronger acid suppression only as needed, then reduce to the lowest treatment that keeps symptoms away.
  • Self-care: Losing weight if overweight, eating smaller meals, not eating within a few hours of lying down, raising the head of the bed, cutting down on alcohol, caffeine, fatty or spicy foods and other personal triggers, stopping smoking and avoiding tight clothing around the waist can all reduce reflux — sometimes enough to avoid or minimise medication.
  • When to seek help: See your GP urgently if you have difficulty or pain swallowing, food sticking, unintentional weight loss, persistent vomiting, vomiting blood or passing black tarry stools, or if heartburn symptoms persist despite treatment — these need prompt assessment, sometimes with a camera test (endoscopy).

What it is

Acid reflux happens when stomach contents, including acid, flow back up into the oesophagus (the gullet). The valve-like muscle at the top of the stomach normally keeps this from happening, but if it relaxes too easily, acid escapes upwards and irritates the sensitive lining. Occasional reflux is very common and harmless; when it is frequent or troublesome it is called gastro-oesophageal reflux disease, or GORD. Typical symptoms are heartburn (a burning feeling behind the breastbone), an unpleasant sour or acid taste, regurgitation, and sometimes a cough, hoarseness or disturbed sleep. It is often linked to being overweight, eating large or late meals, certain foods, alcohol, smoking, pregnancy or some medicines. While usually a quality-of-life problem rather than a dangerous one, certain symptoms can point to something more serious and need prompt assessment.

How it is treated

Treatment follows a step-up, step-down principle: start with the simplest measures and add stronger acid suppression only as needed, then reduce to the lowest treatment that keeps symptoms away. Lifestyle changes come first and continue throughout. For mild or occasional symptoms, antacids and alginates give quick, on-demand relief. If symptoms are more persistent, acid-reducing medicines are used — proton pump inhibitors (PPIs) are the mainstay because they suppress acid most effectively, with H2-receptor antagonists offering milder suppression or a step-down option. The aim is to use the lowest effective treatment for the shortest time that controls symptoms, reviewing regularly rather than continuing strong acid suppression indefinitely without reason. Because reflux-type symptoms can occasionally mask other conditions, a careful check for warning features is part of every assessment.

Each links to a full, dose-free guide — what it is, how it works, who can and cannot use it, side effects, interactions and FAQs.

Antacids and alginates Gastrointestinal Provide fast, on-demand relief by neutralising acid and forming a protective raft on top of the stomach contents; useful for mild or occasional symptoms. H2-receptor antagonists Gastrointestinal Reduce acid production more gently than PPIs; an option for milder symptoms or as a step-down from a PPI. Proton pump inhibitors Gastrointestinal The mainstay for persistent or troublesome reflux; the most effective acid suppression, used at the lowest level that controls symptoms. Domperidone Gastrointestinal Used in selected people to help the stomach empty more promptly, where reflux is linked to slow gastric emptying.

Beyond medication

Lifestyle and self-care

Losing weight if overweight, eating smaller meals, not eating within a few hours of lying down, raising the head of the bed, cutting down on alcohol, caffeine, fatty or spicy foods and other personal triggers, stopping smoking and avoiding tight clothing around the waist can all reduce reflux — sometimes enough to avoid or minimise medication.

Chest pain that could be from the heart — especially with breathlessness, sweating or pain spreading to the arm or jaw — is an emergency; call 999.

Answers

Acid reflux & GORD: frequently asked questions

What medicines are used for acid reflux and GORD?

Antacids and alginates give quick relief for mild or occasional symptoms. For more persistent reflux, acid-reducing medicines are used — proton pump inhibitors (PPIs) are the mainstay, with H2-receptor antagonists as a gentler or step-down option. Domperidone is used in selected cases to help the stomach empty. Treatment is matched to how troublesome the symptoms are.

What does step-up, step-down treatment mean?

It means starting with the simplest, lowest treatment that might work — such as lifestyle change and antacids — and stepping up to stronger acid suppression only if needed. Once symptoms are controlled, treatment is stepped back down to the lowest level that keeps them away, rather than staying on strong medicines indefinitely without review.

Which symptoms of reflux are warning signs?

Difficulty or pain when swallowing, food sticking, unintentional weight loss, persistent vomiting, vomiting blood, or black tarry stools are red-flag symptoms that need urgent assessment, often with an endoscopy. Heartburn that does not settle with treatment should also be reviewed.

Can I just keep taking antacids?

Antacids are fine for occasional heartburn, but if you need them regularly it is a sign your reflux should be reviewed. Frequent symptoms are usually better managed with lifestyle changes and, where appropriate, acid-reducing medicines, and persistent or worsening symptoms should always be assessed.
