Gaviscon Double Action provides dual relief from heartburn and indigestion symptoms and is formulated to work in two ways. It not only creates a protective barrier over your stomach to stop refluxing acid causing discomfort, it also neutralises excess stomach acid. This effective two-pronged approach helps to relieve you from discomfort.

Stress can be a contributor - which is all the more reason to adopt healthy ways of dealing with stress. It depletes prostaglandins in our body, which protect us from stomach acid.

Try to:

  • Get a good night’s sleep. A lack of sleep can lead to higher stress levels
  • Exercise - this boosts wellbeing.
  • Eat more slowly and mindfully
  • Try to avoid unhealthy lifestyle habits

You might also try reducing your meal-sizes and watching how much spicy food you eat (a trigger).

Pregnant mothers are also much more likely to suffer from heartburn and indigestion. A growing baby bump puts pressure on your system, and makes refluxing acid a very common reality of pregnant life.

If you’re suffering from heartburn twice-weekly or more, you could consider pairing Gaviscon Double Action with Guardium.

Guardium is designed to provide long-lasting relief for recurrent sufferers. Please have a look at our Guardium page to find out more.
