Dyspepsia has many possible causes- some easily diagnosed and others difficult to define. Dyspepsia is persistent or recurring abdominal pain that's centered in the upper abdomen and that lasts more than four weeks. People with dyspepsia also may experience bloating, nausea, burping and a feeling of fullness that occurs soon after eating.
Symptoms usually develop after meals.
Motility-like dyspepsia, in which the primary symptoms may be bloating, fullness and gas distention of the abdomen. Reflux-like dyspepsia, in which the primary symptom is similar to that of heartburn. Many patients may experience multiple symptoms. Dyspepsia is similar to, but not the same as, some common gastrointestinal disorders. Dyspepsia also should be distinguished from functional bowel diseases of the lower GI tract, such as irritable bowel syndrome or spastic colon.
