Indigestion defined

INDIGESTION is a general term used to describe pain or discomfort in the upper abdomen or chest that can develop after a meal. Sometimes a burning feeling is felt in the chest, and this is known as heartburn. Most people have suffered from indigestion after a large meal at some time, and up to 20% of people suffer from heartburn at least once a week. 

Pain felt in the upper abdomen may come and go. For some people it can be relieved by food, especially if it feels like a hunger pain, although for others it can occur after eating. It can occur by day or at night, when it may be relieved by a snack or a drink of milk. Alternatively, it can occur without any relation to food at all.
