Acid reflux refers to the movement of acid from your stomach – where it should be – up into your oesophagus (food pipe) – where it shouldn’t be. This can cause a burning feeling in your chest and throat, also known as heartburn. That’s because the lining of your oesophagus is much more sensitive to acid than your stomach and contact with it can cause irritation to its lining.
WHAT CAUSES ACID REFLUX?
There are many reasons as to why the valve at the top of your stomach, the lower oesophageal sphincter, might not work as it should to keep stomach acid in the stomach. Pregnancy, being overweight, and even stress can be factors, but a very common cause is diet-related. The foods that trigger acid reflux may be different between people but, if you suffer from acid reflux and heartburn, there are some common culprits which you may want to avoid.
