If this acid refluxes into your gullet, it can cause heartburn which is a burning pain behind your breastbone. This heartburn sometimes comes with a bitter liquid rising into your mouth. A burning sensation is often caused by this painful irritation in the stomach. Indigestion may also be because the lining of your digestive system is overly sensitive to acid. There are also other factors that can cause indigestion such as smoking, drinking alcohol, stomach infections, ulcers, or an unhealthy and stressful life. (“Indigestion – Causes – NHS Choices,” n.d.)
