Home Remedies for Heartburn: What Works and What Doesn’t

Quick answer

Eat smaller, sit upright, avoid triggers; see a doctor if it is frequent

The most effective home measures are smaller meals, not lying down for 2–3 hours after eating, raising the head of the bed, losing excess weight, avoiding personal triggers (fatty or spicy food, alcohol, coffee, chocolate, mint, large meals) and quitting smoking. Chewing gum increases saliva that neutralises acid, and a little baking soda in water gives short-term relief, though it is high in sodium. Ginger may soothe, while remedies such as apple cider vinegar, milk and raw almonds lack good evidence. Heartburn more than twice a week, trouble swallowing, weight loss, vomiting or black stools need medical assessment.

Important. Chest pain with pressure or tightness, pain spreading to the arm, jaw or back, breathlessness, sweating or fainting needs emergency care, since heart attack can feel like heartburn. Vomiting blood, black stools, difficulty swallowing or unexplained weight loss need prompt assessment.

Why heartburn happens

A ring of muscle at the lower end of the oesophagus (the lower oesophageal sphincter) normally closes after food passes into the stomach. If it relaxes at the wrong time, or pressure in the stomach rises after a large meal, acid washes up into the oesophagus and causes a burning sensation, often with a sour taste or regurgitation. Occasional heartburn is common; frequent heartburn is called gastro-oesophageal reflux disease (GORD or GERD). See acidez de estómago (Spanish).

Habits that help most

Eat smaller meals and avoid large, heavy dinners.
Wait 2–3 hours between your last meal and lying down.
Raise the head of your bed by 15–20 cm with blocks or a wedge; extra pillows alone are less effective.
Sleep on your left side, which may reduce night-time reflux.
Lose excess weight, particularly around the waist.
Wear loose clothing around the stomach.
Stop smoking and limit alcohol.
Eat slowly and avoid eating just before exercise.

Foods and drinks to cut back

Fatty and fried foods, fast food and creamy sauces.
Spicy dishes, onions and garlic (in some people).
Chocolate and peppermint.
Coffee, caffeinated and fizzy drinks.
Alcohol, particularly with meals and late at night.
Citrus fruits and juices, tomato-based foods in people who find them irritating.
Keep a food diary for 2–3 weeks to find your own triggers; not everyone reacts to all of these. See foods to avoid with acid reflux.

Quick home remedies with some support

Chewing sugar-free gum for 30 minutes after meals increases saliva and swallowing, which clears acid.
Antacids (calcium carbonate, magnesium or aluminium hydroxide) neutralise acid within minutes; follow the label and ask a pharmacist if you take other medicines.
Alginates (such as Gaviscon) form a raft that floats on stomach contents and reduces reflux.
Baking soda (sodium bicarbonate) in water gives fast relief, but should be occasional because of its high sodium content and effect on stomach pH; avoid it if you have high blood pressure, kidney or heart problems, or are pregnant, unless advised.
Ginger as tea or fresh in cooking may soothe the stomach; evidence is modest.
Water: small sips can wash acid down temporarily.
Standing or sitting upright after eating rather than slouching.

Remedies with little evidence

Apple cider vinegar: no good evidence, and acid can irritate the oesophagus.
Milk: may soothe for a few minutes, but fat and protein can stimulate more acid afterwards.
Raw almonds, honey, aloe vera juice and herbal teas: anecdotal; some people feel better, others do not.
Peppermint tea: relaxes the sphincter and may worsen reflux.
Chamomile tea: calming but evidence is limited.
If a remedy helps you and does not harm, it is reasonable; do not rely on it if symptoms persist.

Over-the-counter and prescription medicines

Antacids and alginates work quickly but briefly. Histamine-2 blockers (famotidine) reduce acid for several hours. Proton pump inhibitors (omeprazole, esomeprazole, lansoprazole, pantoprazole) are the most effective for frequent heartburn; over-the-counter courses are usually 14 days. If you need them regularly, see a doctor to review the cause and the dose; long-term use needs supervision. Some common medicines (anti-inflammatories, certain blood pressure drugs, bisphosphonates) can cause or worsen heartburn.

Heartburn in pregnancy

Heartburn is very common in pregnancy because of hormonal changes and the growing uterus. Eat small meals, avoid lying down after eating, raise the head of the bed and ask your midwife or doctor about antacids and alginates that are suitable. Avoid sodium bicarbonate and products with high sodium or aspirin-containing remedies unless advised.

When it might not be heartburn

Heart attack and angina can cause burning or pressure in the chest, particularly with exertion, and may be mistaken for heartburn. Features that suggest the heart include pressure or tightness, pain spreading to the arm, jaw or back, breathlessness, sweating, nausea, faintness and a link to exertion, particularly in people over 40 or with risk factors. If in doubt, call emergency services.

When to see a doctor

Heartburn more than twice a week, or needing antacids most days.
Difficulty or pain swallowing, or food sticking.
Unintentional weight loss, persistent vomiting, black stools or anaemia.
Hoarseness, chronic cough or throat symptoms. See burning throat.
No improvement after 2–4 weeks of lifestyle changes and treatment.
Age over 55 with new symptoms.
Chest pain (call emergency services if severe).

Three common situations

Heartburn after a large evening meal with wine: eat earlier and smaller, limit alcohol and raise the head of the bed.

Night-time heartburn that wakes you: avoid late meals, elevate the bed, sleep on your left side and ask about treatment.

Heartburn that returns as soon as an antacid wears off: see a doctor to review the diagnosis and medicines.

Key points to remember

Smaller meals, an upright posture, trigger avoidance, weight control and bed elevation are the best home remedies for heartburn. Short-term antacids can help, but frequent heartburn or warning signs need medical review. Our nutrition team can help you plan reflux-friendly meals.
