Indigestion, also known as dyspepsia, is a term used to describe symptoms including a feeling of fullness, discomfort or a burning sensation in the abdomen after meals. It is most common in adults and can occur occasionally or every day. Often these symptoms can be managed and suppressed with the appropriate medication or dietary changes. Frequent indigestion can often be the sign of a more serious underlying condition, so it�s best to consult your doctor if the problem persists.
