NHS warns persistent heartburn may signal oesophageal cancer in the UK

The NHS has issued a warning that persistent heartburn may indicate oesophageal cancer, which claims about 8,000 lives annually in the UK. This symptom, often mistaken for holiday overindulgence, should be monitored closely. Heartburn is caused by stomach acid rising into the throat and can be triggered by rich foods and alcohol. The NHS advises seeing a doctor if heartburn occurs most days for three weeks or more, as it may signal a serious condition. Other symptoms to watch for include difficulty swallowing, unexplained weight loss, and persistent cough. While these symptoms can have various causes, the NHS emphasizes the importance of consulting a GP if they worsen or change.
