Condition

Acid reflux (GERD)

Stomach acid flowing back into the oesophagus, causing heartburn and regurgitation.

See a clinician

Some causes of acid reflux (gerd) need medical care, not self-treatment. Seek help for any of these:

  • Difficulty or pain swallowing, unintentional weight loss, or vomiting blood / black stools
  • New reflux after age 60, or chest pain (always exclude a heart cause first)

What may help

Remedies studied for acid reflux (gerd), ranked by strength of evidence.

  • B
    Alginate chemical

    Effective for relieving reflux symptoms — it forms a floating gel raft over stomach contents.

  • C
    DGL (deglycyrrhizinated licorice) herb

    May modestly reduce heartburn and reflux symptoms; evidence is limited and mostly for one branded extract.

  • Melatonin supplement

    A few small studies suggest reflux symptom benefit, but the evidence is preliminary.

Lifestyle changes and acid-suppressing medication are mainstays. Alginates (the “raft” antacids) have solid evidence for symptom relief; DGL licorice and melatonin are weaker.
