Acid reflux occurs when stomach acid flows back into the oesophagus, causing heartburn, regurgitation and sometimes chronic cough or throat irritation. Our pharmacists help you recognise common triggers—such as fatty meals, caffeine, alcohol and late-night eating—and suggest practical, evidence-based changes. We explain medication options, from quick-relief antacids to longer-term proton pump inhibitors, and consider interactions with your current medicines. For recurring or severe symptoms we can advise when tests or specialist referral are appropriate, offering a clear plan to reduce discomfort and protect your digestive health.
