Key facts

Oesophageal spasms at a glance.

The essentials, in plain English. What the disorder is, how it is classified and how it is investigated and treated in the UK today.

  • What it is

    An oesophageal motility disorder in which the muscle of the oesophagus contracts abnormally, causing chest pain, dysphagia or regurgitation.

  • How it is classified

    Chicago Classification 4.0 (2021) groups spastic and disordered peristalsis into distal oesophageal spasm, hypercontractile oesophagus, achalasia, EGJOO and ineffective motility.

  • Why it matters

    Chest pain from oesophageal spasm closely mimics cardiac pain, so a cardiac cause must always be excluded first.

  • Gold-standard test

    High-resolution oesophageal manometry (HRM) interpreted with Chicago 4.0 is the definitive test.

  • Common overlap

    Gastro-oesophageal reflux disease coexists in many patients and can drive or worsen spasm.

  • Treatment idea

    Stepped care: treat reflux, then smooth-muscle relaxants, neuromodulators, endoscopic therapy and, in selected cases, POEM.

Why this guide matters

Chest pain first, then the oesophagus.

Oesophageal spasm is a diagnosis of exclusion. These three principles shape everything else on the page.

  • Cardiac disease is excluded first

    Symptoms overlap closely with angina. ECG, troponin and, where appropriate, coronary angiography come before any oesophageal workup.

  • Chicago 4.0 organises the diagnosis

    High-resolution manometry categorises distal spasm, hypercontractile oesophagus, achalasia, EGJOO and ineffective motility - each has its own treatment path.

  • Coexisting reflux is common

    Gastro-oesophageal reflux disease often drives or amplifies spasm and is frequently the first thing to treat.

The classification

Chicago Classification 4.0 - five families of motility disorder.

A manometry-led framework, updated in 2021, that groups oesophageal motility problems into distinct clinical patterns.

  • Distal oesophageal spasm (DES)

    Premature, high-amplitude contractions with normal relaxation of the lower oesophageal sphincter. Often presents with chest pain.

  • Hypercontractile (jackhammer) oesophagus

    Repetitive, very high-amplitude peristaltic contractions. Presents with chest pain, dysphagia and sometimes reflux.

  • Achalasia

    Failure of lower oesophageal sphincter relaxation with three manometric variants (types I, II and III). See our achalasia guide.

  • Oesophagogastric junction outflow obstruction (EGJOO)

    Impaired relaxation at the gastro-oesophageal junction without meeting the criteria for achalasia. Requires structural exclusion.

  • Ineffective oesophageal motility

    Weak or absent peristalsis in a large proportion of swallows. Often reflux-related and typically presents with dysphagia.

  • Secondary drivers

    Reflux disease, systemic sclerosis, diabetic autonomic neuropathy and Chagas disease can mimic or coexist with primary motility disorders.

How the diagnosis is made

From chest pain to a Chicago 4.0 label.

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

  1. 01

    Assessing

    Rule out cardiac chest pain

    ECG, troponin and, where the picture is suspicious, stress testing or coronary angiography before labelling pain as oesophageal.

  2. 02

    Assessing

    Careful symptom history

    Character, triggers (hot, cold, stress, alcohol, caffeine), pattern of dysphagia to solids and liquids, and reflux overlap.

  3. 03

    Assessing

    Upper GI endoscopy (OGD)

    Gastroscopy excludes strictures, oesophagitis, eosinophilic oesophagitis and malignancy before motility testing.

  4. 04

    Confirming

    High-resolution manometry

    The gold-standard test. HRM with Chicago 4.0 confirms distal oesophageal spasm, hypercontractile oesophagus, achalasia or EGJOO.

  5. 05

    Confirming

    Barium swallow if needed

    A classic corkscrew or rosary-bead appearance supports distal oesophageal spasm and shows structural anatomy.

  6. 06

    Confirming

    24-hour pH-impedance

    Reserved for reflux screening and unexplained symptoms, usually alongside HRM in a specialist motility service.

  7. 07

    Planning

    Referral to upper-GI motility

    A specialist motility MDT assembles the tests, agrees the Chicago 4.0 diagnosis and shapes a personalised plan.

Typical pathway: cardiac clearance, gastroscopy and manometry within weeks in a specialist service.

Symptoms

What oesophageal spasm feels like.

A characteristic pattern of chest pain, intermittent dysphagia and reflux overlap. And the features that mean urgent review is needed.

  • Chest pain

    Squeezing or gripping retrosternal pain that closely mimics cardiac pain and must never be assumed non-cardiac without workup.

  • Intermittent dysphagia

    Difficulty swallowing that comes and goes, often affecting both solids and liquids in the same episode.

  • Regurgitation

    Undigested food or saliva returning to the mouth, sometimes minutes after eating and unrelated to nausea.

  • Heartburn overlap

    Reflux symptoms are common because GORD often coexists with spastic motility disorders.

  • Trigger-driven episodes

    Very hot or very cold food and drinks, alcohol, caffeine and stress commonly precipitate an episode.

  • Sensation of food sticking

    A feeling that food is trapped behind the breastbone, sometimes relieved by drinking water.

  • Weight loss (uncommon)

    Significant weight loss is unusual and raises concern for achalasia or an alternative diagnosis such as malignancy.

  • Red flag - progressive dysphagia

    Steadily worsening swallowing, especially for solids, needs urgent gastroscopy to exclude structural disease.

Treatment

How oesophageal spasms are treated.

A stepped approach - treat reflux first, then smooth-muscle relaxants and neuromodulators, then endoscopic therapy or POEM for refractory disease.

  • Treat coexisting reflux

    A trial of a proton pump inhibitor to treat gastro-oesophageal reflux disease is often the first practical step and can improve spasm.

  • Calcium channel blockers

    Nifedipine or diltiazem, taken orally or sublingually before meals, relaxes oesophageal smooth muscle in distal oesophageal spasm.

  • Nitrates

    Sublingual isosorbide dinitrate can abort an acute episode by relaxing smooth muscle, useful as a rescue therapy.

  • PDE5 inhibitors

    Sildenafil has some evidence in spastic motility disorders and is used off-label in specialist practice.

  • Tricyclic neuromodulator

    Low-dose amitriptyline or imipramine reduces visceral hypersensitivity and functional oesophageal chest pain.

  • Gabapentinoid or duloxetine

    Selected patients benefit from gabapentinoids or duloxetine as neuromodulators when TCAs are unsuitable.

  • Botulinum toxin injection

    Endoscopic botulinum toxin to the lower oesophageal sphincter helps hypercontractile oesophagus, distal spasm and achalasia type III.

  • Peroral endoscopic myotomy (POEM)

    A specialist-commissioned endoscopic myotomy for spastic disorders and achalasia type III, offered in tertiary UK centres.

Adjunctive care

Psychological therapy, dilatation and trigger management.

Cognitive behavioural therapy and gut-directed hypnotherapy (the Manchester model) have strong evidence in functional oesophageal chest pain. Pneumatic dilatation is a specialist option for selected patients with achalasia or EGJOO, and identifying and avoiding personal triggers (very hot, very cold, alcohol, caffeine, stress and specific foods) is a durable low-risk intervention. Complex cases are best managed within a gastroenterology and upper-GI motility MDT.

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 chest pain is severe, new or worsening, seek urgent medical care.

Red flags

When oesophageal symptoms need urgent attention.

Most oesophageal chest pain and dysphagia is manageable, but these features are not - and mean a specialist opinion, sometimes urgently.

  • Cardiac chest pain first

    Never assume chest pain is oesophageal. Sudden, severe, exertional or radiating pain needs urgent cardiac assessment.

  • Progressive dysphagia

    Worsening difficulty swallowing solids, or food sticking, needs urgent gastroscopy to exclude cancer or a stricture.

  • Unintentional weight loss

    Weight loss with swallowing symptoms is a red flag for oesophageal or gastric cancer and warrants a two-week wait referral.

  • Anaemia or GI bleeding

    Iron deficiency, melaena or haematemesis alongside swallowing symptoms needs urgent investigation.

  • Aspiration or nocturnal choking

    Coughing on food, recurrent chest infections or waking choking may signal severe achalasia or reflux and needs specialist review.

  • Age over 55 and new symptoms

    New dyspepsia or dysphagia in this group triggers urgent endoscopy under NICE guidance.

  • Autoimmune features

    Raynaud phenomenon, skin thickening or joint symptoms may suggest systemic sclerosis driving oesophageal dysmotility.

  • Travel history

    Prolonged travel or residence in Latin America raises the possibility of Chagas disease as a secondary cause.

Living with it

A treatable condition, with a clear ladder.

Four practical priorities day to day - trigger awareness, gut-brain therapy, timely manometry and staying within an MDT for anything complex.

A quiet reminder

If pain is severe, new or worsening, call 999.

Because cardiac and oesophageal chest pain overlap so closely, no one should self-diagnose an acute episode.

  1. 01 Diet

    Learn your triggers

    Very hot and very cold drinks, alcohol, caffeine and rapid eating often provoke episodes. Small, warm meals eaten slowly help.

  2. 02 Stress

    Manage the gut-brain axis

    Cognitive behavioural therapy and gut-directed hypnotherapy (the Manchester model) have real evidence in functional oesophageal disorders.

  3. 03 Escalate

    Ask for HRM if unclear

    If symptoms persist despite reflux treatment, request high-resolution manometry through your GP or gastroenterology team.

  4. 04 Follow up

    Stay within an MDT

    Complex spastic disorders benefit from a specialist motility MDT that can offer botulinum toxin, dilatation or POEM.

Frequently asked

Common questions about oesophageal spasms.

Quick answers on cardiac exclusion, manometry, medication, botulinum toxin and POEM.

  • What are oesophageal spasms?

    Oesophageal spasms are abnormal contractions of the muscle of the oesophagus that cause chest pain, difficulty swallowing or regurgitation. Under the Chicago Classification 4.0 they fall within a family of oesophageal motility disorders, including distal oesophageal spasm, hypercontractile (jackhammer) oesophagus, achalasia, oesophagogastric junction outflow obstruction (EGJOO) and ineffective motility.

  • How is it different from a heart attack?

    Symptoms overlap closely, so cardiac disease must always be excluded first with an ECG, troponin and, where suspicion is high, stress testing or coronary angiography. Only when a cardiac cause has been ruled out is it safe to investigate an oesophageal source.

  • What is the gold-standard test?

    High-resolution oesophageal manometry (HRM), interpreted with the Chicago Classification 4.0, is the gold-standard test. It is usually preceded by gastroscopy to rule out structural disease and may be paired with 24-hour pH-impedance testing.

  • Do proton pump inhibitors help?

    Yes, when reflux coexists. Gastro-oesophageal reflux disease is a common driver or amplifier of spasm, so a proton pump inhibitor trial is a reasonable early step and can settle symptoms without further intervention.

  • When is botulinum toxin or POEM used?

    Endoscopic botulinum toxin injection to the lower oesophageal sphincter is used for hypercontractile oesophagus, distal oesophageal spasm and achalasia type III. Peroral endoscopic myotomy (POEM) is a specialist procedure offered in tertiary UK centres for spastic disorders and achalasia type III when medical therapy fails.

  • Can stress cause oesophageal spasm?

    Stress does not cause the underlying disorder, but it is a well-recognised trigger and amplifier of symptoms. Gut-directed hypnotherapy and cognitive behavioural therapy have good evidence for functional oesophageal chest pain and visceral hypersensitivity.
