What is the difference between heartburn & indigestion?
Although people often use the terms interchangeably, there is a difference between heartburn and indigestion.
Indigestion causes heartburn - the burning feeling or heat that begins in your chest or throat and occurs in waves. Most often this happens when acid from the stomach rises into the oesophagus and upwards to cause pain and discomfort.
Indigestion is literally an ‘inefficient digestion’ and is a general term used for a collection of symptoms that include heartburn, but covers any pain or discomfort felt in the stomach region after meals. It is often triggered by eating or drinking things that make the stomach produce large amounts of acid, such as spicy foods or alcohol.
