Heartburn and sore throat

Acid reflux can move upwards from the stomach and irritate the oesophagus or throat. A person may notice burning, a sour taste, throat clearing, hoarseness, cough, or soreness that is worse after meals or on waking. Reflux-related discomfort does not usually explain every sore throat.

A sore throat can also occur with a common cold, influenza, COVID-19, tonsillitis, strep throat, glandular fever, or allergic rhinitis. Fever, blocked or runny nose, cough, swollen neck glands, marked fatigue, or sudden throat pain may point towards another cause. The symptom pattern helps a clinician decide whether testing or examination is needed.

For possible reflux, avoid lying down soon after eating, reduce foods that clearly trigger burning, and keep your upper body raised when resting. For throat discomfort, drink fluids, choose soothing foods, and avoid smoke or other irritants. Do not start antibiotics without medical advice; they do not treat every sore throat.

Arrange a clinical review if soreness keeps returning, lasts longer than expected, or occurs with frequent reflux, swallowing difficulty, or voice change. A pharmacist can advise on symptom relief, while a doctor can assess whether reflux, allergy, or infection is more likely.

Seek urgent help if you cannot swallow saliva, are drooling, have noisy or difficult breathing, rapidly worsening throat swelling, severe dehydration, or confusion. Get prompt medical advice for a high fever, severe one-sided throat pain, a muffled voice, a stiff neck, or a rash. These features should not be attributed to heartburn without assessment.

Tell the clinician whether soreness follows meals, is worse on waking, or comes with fever, cough, nasal symptoms, swollen glands, or hoarseness. Ask whether you need a throat examination or test and whether reflux treatment could be contributing to improvement.
