It is worth cutting back on tomato based foods like chilli, pasta and pizza sauces with tomatoes in it as tomatoes are known to cause an increase in stomach acids, which in turn can trigger heartburn and GERD symptoms.
If your acid reflux and heartburn is worse at night, try raising the head of the bed. That way your esophagus is higher up than your stomach and less acid would trickle back up the wrong way. But before you start chopping off two legs of the bed, or put bricks under two others, adding another pillow or two could do the trick too.
Keep a food diary to track everything you eat and drink if you suffer from acid reflux as diet plays a part in generating stomach acid, and if the acid levels are managed and kept low then you are less likely to experience the reflux.
