Also Known As: Indigestion, Dyspepsia, Upset stomach
Dyspepsia (from the Greek δυσ- dys- and πέψις pepsis "digestion"), also known as upset stomach or indigestion, refers to a condition of impaired digestion. It is a medical condition characterized by chronic or recurrent pain in the upper abdomen, upper abdominal fullness and feeling full earlier than expected when eating. It can be accompanied by bloating, belching, nausea, or heartburn. Dyspepsia is a common problem, and is frequently associated with, gastroesophageal reflux disease (GERD) or gastritis. In a small minority it may be the first symptom of peptic ulcer disease (an ulcer of the stomach or duodenum) and occasionally cancer.
Dyspeptic symptoms are often caused by medication, such as calcium antagonists (used for angina or high blood pressure), nitrates (used for angina), theophylline (used for chronic lung disease), bisphosphonates, corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs, used as painkillers).
