Acid Reflux Sore Throat: Immediate Relief and Long-Term Fixes

01What

How reflux makes the throat sore

The lower oesophageal sphincter normally prevents stomach contents from moving upward. When it relaxes or pressure rises, acid and pepsin can reach the oesophagus (GORD) and sometimes the throat and voice box (LPR). The lining of the throat is far more sensitive to acid than the oesophagus, so even small amounts can cause soreness, swelling and cough. See laryngopharyngeal reflux and burning throat.

02Symptoms

Symptoms that suggest reflux

• Sore, raw or burning throat, often worse in the morning or after meals.
• Hoarseness or a voice that tires easily. See hoarseness.
• Frequent throat clearing, and a feeling of mucus or a lump. See lump in throat.
• Chronic dry cough, particularly after meals or lying down. See dry cough at night.
• Bitter or sour taste, bad breath.
• Difficulty swallowing or a sensation of food sticking.
• Heartburn or regurgitation may be absent in LPR.
• Worse after large, late or fatty meals, alcohol or coffee.

03Now

Immediate relief

• Sip water or warm, non-acidic drinks (herbal tea such as chamomile or ginger).
• Take an alginate (Gaviscon or similar) after meals and at bedtime; it forms a protective raft.
• Take an antacid (calcium carbonate or magnesium hydroxide) for quick neutralisation.
• Sit upright, loosen tight clothing and avoid bending over.
• Chew sugar-free gum to increase saliva and clear acid.
• Gargle with water to rinse acid from the throat.
• Avoid lying down for 2–3 hours after eating.
• Ask a pharmacist if you are pregnant or take other medicines.

04Eat

Eating and drinking habits

• Eat smaller meals and chew slowly.
• Finish dinner at least 3 hours before bed.
• Limit trigger foods and drinks: fatty and fried foods, chocolate, coffee, mint, tomato, citrus, spicy food, carbonated drinks and alcohol.
• Favour oatmeal, bananas, melon, green vegetables, lean proteins, ginger and non-citrus fruits. See foods to avoid with acid reflux.
• Drink plenty of water between meals.
• Identify your triggers with a food diary.
• Avoid late-night snacks.

05Life

Lifestyle changes with strong evidence

• Raise the head of the bed by 15–20 cm with blocks or a wedge, not just pillows.
• Sleep on your left side if possible.
• Lose weight if overweight, particularly around the waist.
• Stop smoking and limit alcohol.
• Wear loose clothes around the waist.
• Avoid heavy lifting and bending after meals.
• Manage stress, which can worsen symptoms.
• See home remedies for heartburn.

06Medical

Medical treatment

• Proton pump inhibitors (omeprazole, esomeprazole, lansoprazole, pantoprazole), usually taken 30–60 minutes before meals for 8–12 weeks, sometimes twice daily initially; the evidence in LPR is mixed, so treatment is reviewed after a trial.
• H2 blockers (famotidine) at night.
• Alginates as add-on therapy.
• Prokinetics in selected cases.
• Laryngoscopy to look at the throat and rule out other causes.
• Endoscopy or reflux monitoring for persistent or alarm symptoms.
• Anti-reflux surgery (fundoplication) for severe, proven, treatment-resistant reflux.
• Long-term PPI use should be reviewed periodically.

07Ddx

Other causes to consider

• Postnasal drip from allergy or sinus problems. See post nasal drip sore throat.
• Viral or bacterial pharyngitis. See pharyngitis.
• Dry throat from mouth breathing. See dry throat.
• Smoking and irritants.
• Voice overuse.
• Tonsil stones.
• Rarely, tumours of the throat or oesophagus; persistent symptoms must be checked.

09Cases

Three common situations

A person who wakes with a sore throat and sour taste after late dinners: earlier, lighter dinners, raise the bed and use an alginate.

A teacher with hoarseness and throat clearing but no heartburn: silent reflux is possible; get a throat check and a trial of treatment.

A smoker with a sore throat and difficulty swallowing for six weeks: needs prompt ENT and upper GI assessment.

10Pregnancy

Reflux and sore throat in pregnancy and in children

Reflux is very common in pregnancy because of hormonal changes and a growing uterus; the same measures apply (small meals, no late dinners, head elevation) and your midwife or doctor can advise on safe antacids and alginates. In babies, reflux is common and usually resolves by 12–18 months; frequent spitting with poor weight gain, irritability or breathing symptoms needs a paediatric review. Older children with persistent throat clearing, cough or hoarseness may have reflux, but allergies and sinus drip are more common causes.

11Night

Night-time reflux: practical tips

• Eat your last meal at least 3 hours before bed.
• Raise the head of the bed with 15–20 cm blocks; a wedge pillow is an alternative.
• Sleep on your left side.
• Take an alginate at bedtime if your doctor or pharmacist agrees.
• Avoid alcohol and heavy meals in the evening.
• Keep a glass of water by the bed for sips if you wake with irritation.
• If you wake choking or coughing, mention it to your doctor, because it can signal significant reflux or sleep apnea.

12Summary

Key points to remember

Acid reflux can irritate the throat without heartburn. Use alginates or antacids for quick relief, change meal timing, triggers and bed position, and seek review for persistent or alarm symptoms. Our ENT team can examine your throat and guide treatment.
