Good to know

Heartburn, reflux or indigestion?

Heartburn is a symptom: a burning pain or discomfort in the chest, often after a meal or when you lie down or bend over, that can feel as if it is rising towards your neck or throat. It happens when stomach acid moves up into the oesophagus. If it happens 2 times a week or more, see your doctor, because it could be gastro-oesophageal reflux disease (GORD), the ongoing condition covered on our acid reflux page. Discomfort centred in the upper tummy, with feeling full too soon, burping or bloating, is closer to indigestion.

Getting the most from occasional relief

Wait about 3 hours after eating before lying down, and avoid vigorous exercise soon after a meal. Loose clothing, stopping smoking and losing weight if you are overweight can also help. Antacids neutralise stomach acid, while low-dose proton pump inhibitors (PPIs) from a pharmacy work best taken 30 to 60 minutes before a meal. Ask a pharmacist before using either if you are pregnant or take other medicines, and see your doctor if over-the-counter medicines don't help or you find yourself relying on them.

Not sure it's heartburn? If you have chest pain and can't tell whether it is heartburn or a heart attack, call Triple Zero (000), and see our chest pain page.
