Dyspepsia is a Greek word meaning “duis” (bad or difficult) and “peptin” (to digest), which is described by patients as indigestion; both these words are a poor expression, as dyspepsia has no relation to digestion of food. Dyspepsia refers to upper abdominal symptoms usually following intake of food, which appear to arise from an abnormality in the upper gastrointestinal tract. Dyspepsia is a symptom and not a diagnosis. Symptoms may last for decades (even lifetime) and remissions and relapses are common. It is one of the commonest gastrointestinal malady affecting at least 25% of the population during a year. Its prevalence varies in different countries, depending upon the prevalence of Helicobacter pylori (H. pylori) infection, obesity, drug - alcohol - tobacco intake and spices in diet; furthermore, a significant and varying number of subjects do not seek medical treatment.1
