Indigestion (Dyspepsia) Definition and Facts. Indigestion is a general term that describes a group of gastrointestinal symptoms that occur together, including pain, a burning feeling, or discomfort in your upper abdomen; feeling full too soon while eating; and feeling uncomfortably full after eating.
WebMD reports that indigestion itself is not a condition; rather, it is a symptom of an underlying issue, whether it is poor diet or disease. Indigestion is triggered by a host of causes that can be grouped as disease-, medication- and lifestyle-induced. WebMD lists ulcers, GERD, pancreatitis, thyroid disease, irritable bowel syndrome and stomach infections as diseases that produce indigestion as a symptom.
