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.

• Does it begin or get worse after eating particular foods?
• Does it begin or get worse after drinking alcoholic or carbonated drinks?
• Do you eat fast?
• Have you been overeating?
• Have you changed your diet? Have you had any spicy foods, high-fiber foods, or fatty foods? Have you had a lot of caffeine?
• What medications are you taking?
• Have you changed medications recently?
• What other symptoms do you have?
• Do you have stomach pain?
• Are you vomiting?

The following tests may be performed:

• Blood tests (depending on the suspected cause)
• Endoscopy (EGD)
• Upper GI and small bowel series (with barium)
