Indigestion is a vague feeling of abdominal discomfort -- possibly including belching, a feeling of fullness, bloating, and nausea.

Indigestion is usually not a serious health problem, unless it comes with other symptoms.

Indigestion is a common problem. It may be triggered by eating particular foods, or drinking wine or carbonated drinks. It may also be caused by eating too fast or by overeating. Some people may find that spicy foods, high-fiber foods, fatty foods, or too much caffeine can all make this problem worse. Symptoms may be worsened by anxiety and depression.

Rarely, the discomfort of a heart attack is mistaken for indigestion.

Indigestion can be a symptom of a bowel disease like nonulcer dyspepsia.
