What should you know about heartburn and high blood pressure?

High blood pressure often has no obvious symptoms, whereas heartburn is a burning discomfort linked to stomach contents moving into the food pipe. Stress and pain can temporarily raise a blood pressure reading, but heartburn is not a reliable explanation for a high result. Angina and other heart problems can cause pressure, burning or indigestion-like discomfort, particularly with exertion. Obesity, sleep apnoea and kidney disease can affect cardiovascular risk, so the full symptom and health history matters.

If you have a home monitor, sit quietly and measure blood pressure using the technique provided with it; record the reading and your symptoms rather than repeatedly checking in panic. Take prescribed blood-pressure medicines as directed and do not replace them with heartburn remedies. Reduce known reflux triggers, remain upright after meals, and ask a pharmacist to check any antacid against your medicines. Arrange review if burning is new, recurrent, or linked with activity.

Call emergency services for chest pressure or burning that is severe, lasts, returns with exertion, or spreads to the arm, back, neck or jaw, especially with sweating, nausea, breathlessness or faintness. Seek urgent help for sudden weakness, facial drooping, speech trouble, confusion or a severe new headache. Do not wait for a heartburn medicine to work when these signs are present.

Ask how to interpret your readings, whether your chest symptoms need heart testing, and whether any blood-pressure medicine could be contributing to indigestion or reflux.
