How to manage and prevent heartburn
Most people can successfully manage mild heartburn at home by making the following adjustments:
Monitor your diet: Avoid rich, spicy, or fatty foods, as these are common triggers for acid reflux.
Reduce caffeine: Minimise your intake of coffee, tea, and caffeinated soft drinks, which can relax the valve at the entrance to your stomach and allow acid to escape.
Timing of meals: Do not eat too close to bedtime. Aim to finish your last meal at least two to three hours before lying down.
Over-the-counter relief: Consider using heartburn medication, such as antacids or alginates, which can be purchased from a pharmacy to neutralise stomach acid.
