A quarter of Britons suffer from heartburn, a digestive issue that leaves victims with a bitter taste. Caused by stomach acid leaking into the oesophagus, it can be debilitating. In severe cases, GPs prescribe proton pump inhibitors like omeprazole, but many experience sporadic attacks. Causes include medications, ulcers, pregnancy, smoking, obesity, diet, alcohol, and stress.
Pharmacist's Verdict on Popular Remedies
Thorrun Govind, former chair of the Royal Pharmaceutical Society, shares her insights on over-the-counter treatments, stressing that lifestyle changes are crucial.
Milk: 1/5
Milk contains calcium and magnesium that may temporarily neutralise acid, but it can stimulate more acid production. Not suitable for those with dairy intolerance or vegans.
Pepto-Bismol: 2/5
This pink syrup forms a protective coating but contains aspirin, making it unsuitable for pregnant or breastfeeding women, diabetics, or those on certain medications.
Milk of Magnesia: 3/5
Magnesium hydroxide lowers stomach acid but acts as a laxative, causing digestive issues. Not recommended for those with kidney problems.
Rennie: 4/5
These tablets neutralise acid quickly but temporarily. Suitable for pregnant women, but less effective at preventing acid from returning.
Gaviscon: 5/5
Forms a protective foam barrier, preventing acid from moving into the oesophagus. Effective for throat irritation and bad breath.
Expert's Final Thoughts
Govind emphasises that lifestyle factors like diet, exercise, and weight management are key to long-term relief. Over-the-counter remedies should only be used short-term; persistent heartburn requires medical advice.
