1. What you can do right now
Quick help with difficulty swallowing
- Emergency check: shortness of breath, drooling, swelling at the neck or after swallowing a caustic substance – call 112 immediately (in the US: 911) or go to the emergency department.
- Classify the symptom: does it hurt to swallow (odynophagia) or does it get stuck (dysphagia)? Solids or liquids too?
- Take tablets correctly: bisphosphonates, doxycycline and iron preparations upright and with plenty of water, and do not lie down for at least 30 minutes afterwards.
- With a sore throat: warm tea, lozenges, drink enough. With one-sided pain and fever, see a doctor promptly.
- With chronic symptoms: difficulty swallowing over several weeks or weight loss – a gastroscopy is necessary.
EMERGENCY: get medical help immediately!
Sudden difficulty swallowing with shortness of breath, drooling, hoarseness or swelling in the neck (suspicion of epiglottitis or an airway obstruction) – call 112 immediately (in the US: 911). Also after swallowing a foreign body or a caustic substance, with vomiting of blood or black tarry stools, or with one-sided severe throat pain with a high fever and a muffled "hot potato" voice (suspicion of a peritonsillar abscess), act immediately.
2. Understanding difficulty swallowing – what happens in the body?
Difficulty swallowing covers two different phenomena: pain on swallowing (odynophagia) and difficult or obstructed swallowing (dysphagia). The two often occur together but can also occur in isolation – their significance and diagnostics differ.
Acute difficulty swallowing, for example with tonsillitis or reflux oesophagitis, is very common and mostly harmless. Persistent or progressive symptoms – especially in adults with risk factors like smoking, alcohol or ongoing reflux – should be investigated consistently. They can be a sign of a serious illness like oesophageal cancer.
A simple self-test: what gets stuck?
Solids only (bread, meat) → rather a mechanical narrowing (stricture, eosinophilic oesophagitis, tumour). Solids AND liquids → rather a motility disorder (e.g. achalasia). Difficulty initiating the swallow → rather neurological (oropharyngeal dysphagia, e.g. after a stroke). Where do you localise the sticking – high in the throat or deep behind the breastbone?
3. Common causes of difficulty swallowing
3.1 Throat and pharynx
Acute pharyngitis (sore throat): the most common cause of acute pain on swallowing – usually viral. Accompanied by a sore throat, redness, mild fever.
Tonsillitis: severe pain on swallowing, swollen tonsils with whitish coatings, a high fever. With a probably bacterial cause (streptococci), consider antibiotics.
Peritonsillar abscess: one-sided severe pain on swallowing, a pronounced feeling of illness, a muffled voice, trismus. An emergency – drainage necessary.
Glandular fever (infectious mononucleosis): severe throat pain with difficulty swallowing, swollen lymph nodes, tiredness – typical in adolescents and young adults.
Fungal infection (thrush): white coatings in the mouth and throat, pain on swallowing – especially in immunosuppressed people, with inhaled steroids, antibiotic use or diabetes.
Epiglottitis: inflammation of the epiglottis with shortness of breath, a high fever, drooling. An emergency – especially in children.
3.2 Oesophagus
Reflux oesophagitis: the most common cause of chronic difficulty swallowing in adults. Burning behind the breastbone, heartburn, pain on swallowing.
Eosinophilic oesophagitis: a chronic inflammatory disease of the oesophagus, often associated with allergies. The typical symptom: the feeling that solids (bread, meat) get stuck.
Achalasia and other motility disorders: disturbed movement of the oesophagus – dysphagia for solids and liquids, regurgitation, chest pain.
Strictures (narrowings): from chronic reflux, earlier chemical burns or tumour diseases.
Oesophageal diverticulum: outpouchings of the oesophagus, can cause dysphagia and bad breath.
Oesophageal cancer: progressive dysphagia, at first for solid foods, then for liquids too. Risk factors: chronic reflux (Barrett's oesophagus), smoking, alcohol, older age.
3.3 Thyroid and tumours
Enlarged thyroid (goitre): large nodules or goitres can exert pressure on the oesophagus and windpipe – difficulty swallowing, a globus sensation, hoarseness from pressure on the nerve to the vocal cords. More: thyroid nodules.
Thyroid cancer: rare, but important to rule out. Accompanying symptoms: one-sided swelling at the neck, hoarseness, rapidly growing nodules, enlarged lymph nodes.
Tumours of the mouth, throat, larynx: especially in smokers and people with alcohol consumption. Persistent hoarseness, one-sided throat pain, difficulty swallowing, bloody sputum, swollen lymph nodes.
Lymphomas: can affect the neck lymph nodes or tonsils – difficulty swallowing, often with B symptoms (night sweats, fever, weight loss).
3.4 Neurological causes
Stroke: a common cause of acute oropharyngeal dysphagia. An important complication: aspiration with pneumonia.
Parkinson's, multiple sclerosis, ALS: chronic neurodegenerative diseases with increasing dysphagia.
Dementia: swallowing disorders are common in the course – a risk of aspiration. Special food and swallowing training can help.
Myasthenia gravis: exertion-dependent muscle weakness, including of the swallowing muscles.
4. Odynophagia or dysphagia?
With difficulty swallowing, the most important diagnostic question is whether it hurts or whether it gets stuck – the two phenomena have different typical causes and lead to different diagnostics.
| Feature | Odynophagia (pain) | Dysphagia (sticking) |
|---|
| Main symptom | Pain on swallowing | The feeling that food does not slip through |
| Typical causes | Pharyngitis, tonsillitis, reflux oesophagitis, thrush | Achalasia, strictures, eosinophilic oesophagitis, neurological |
| Common course | Acute, often viral, subsides on its own | Chronic, often progressive |
| Most important diagnostics | Inspection, a rapid strep test if needed | Gastroscopy, manometry if needed |
Also important: the globus sensation (globus pharyngeus) – the feeling of a lump in the throat without anything actually getting stuck. Often stress- or reflux-related, usually not a sign of a serious illness. With persistence or accompanying symptoms (hoarseness, weight loss) it should nonetheless be investigated.
5. What really helps
Treatment according to cause
Viral pharyngitis: symptomatic – lozenges, sage tea, painkillers. Antibiotics are not necessary.
Bacterial tonsillitis: with a suspicion of streptococci, an antibiotic if needed.
Reflux oesophagitis: proton pump inhibitors (PPIs), lifestyle changes – small meals, eating nothing late in the evening, raising the upper body.
Eosinophilic oesophagitis: PPIs, topical steroids, an elimination diet with allergies.
Achalasia: endoscopic or surgical procedures (POEM, Heller myotomy).
Strictures: endoscopic dilation (widening).
Tumours: an individual oncological concept (surgery, chemotherapy, radiotherapy).
Neurological dysphagia: speech-therapy swallowing training, adjusting the consistency of food, PEG feeding if needed.
What you can do yourself
With an acute sore throat, warm tea, lozenges, drinking enough and resting the voice help. With reflux: small meals, eating nothing 2–3 hours before going to bed, raising the upper body. Reduce coffee, alcohol, fatty and spicy foods. Stop smoking – this is the most important step not only for reflux but also for cancer prevention.
