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.
