How to manage heartburn: 
A 2 stages guide for your symptoms

Heartburn is never pleasant and depending on the severity of your symptoms, it can prevent you from getting on with your day or doing the things you enjoy. If heartburn is hitting you now, then take a look at Rennie’s 2 stages guide to managing heartburn.


Standing up straight is another simple method to help you relive heartburn symptoms. Your posture can have a huge impact on your digestive system and giving it some space can help relieve the symptoms of heartburn.

Slouching or wearing tight clothing can put increased pressure on your stomach which can lead to heartburn. Standing upright helps to alleviate this pressure which allows the lower oesophageal valve to relax and close properly, preventing any unwanted acid from creeping out of your stomach and up your throat. Simple: but effective!


When it comes to trying to get rid of heartburn, there are plenty of lifestyle adjustments you can make to mitigate your chances of developing symptoms, but when it strikes, antacids like Rennie** are a common choice.

Antacids work by neutralising stomach acid, as opposed to other medications which limit its production. These antacids usually come in a gummy or chalky tablet that can either be chewed or dissolved, and are available over the counter or in shops.

Antacids can be used by just about anyone, although they may cause problems for those with sodium restrictions or kidney problems. They can also be taken during pregnancy, as long as they’re taken according to the pack instructions.

If symptoms are severe or prolonged, you should consult a doctor or pharmacist for advice.
