Heartburn and Indigestion
The feeling of heartburn can be described as a burning pain or discomfort, usually rising from the stomach or upper abdomen and moving upwards towards the neck or throat. People with heartburn may also experience a sensation of food or acid coming back into their throat, which may be accompanied by a bitter or acid taste.
Heartburn symptoms may occur if your stomach produces too much acid in the digestion process. When this happens, stomach acid can move up into the oesophagus (the tube that connects your throat to your stomach), causing discomfort or pain.
Indigestion is a feeling of pain or discomfort, often localised in the upper abdomen and is commonly associated with eating or drinking.
