Dyspepsia (from the Greek "δυς-" (Dys-), meaning har or difficult, and "πέψη" (Pepse), meaning digestion) or indigestion is chronic or recurrent pain in the upper abdomen, upper abdominal fullness and feeling full earlier than expected with eating. It can be accompanied by bloating, belching, nausea or heartburn. Dyspepsia is a common problem, and is frequently due to gastroesophageal reflux disease (GERD) or gastritis, but in a small minority may be the first symptom of peptic ulcer disease (ulcer of the stomach or duodenum) and occasionally cancer. Hence, unexplained newly-onset dyspepsia in people over 55 or the presence of other alarm symptoms may require further investigations.
