Heartburn is a burning feeling in the chest caused by stomach acid travelling up towards the throat (acid reflux). If it keeps happening, it's called gastro-oesophageal reflux disease (GORD).
Speak to a pharmacist for advice if you keep getting heartburn.
They can recommend medicines called antacids that can help ease your symptoms.
It's best to take these with food or soon after eating, as this is when you're most likely to get heartburn. They may also work for longer if taken with food.
