Print Overview Digestive system Enlarge image Close Digestive system Digestive system The major organs in your digestive system are the liver, stomach, gallbladder, colon and small intestine. Indigestion — also called dyspepsia or an upset stomach — is discomfort in your upper abdomen. Indigestion describes certain symptoms, such as belly pain and a feeling of fullness soon after you start eating, rather than a specific disease. Indigestion can also be a symptom of other digestive disorders. Although indigestion is common, each person may experience indigestion in a slightly different way. Symptoms of indigestion may be felt occasionally or as often as daily. Indigestion may often be relieved with lifestyle changes and medicines.Products & ServicesA Book: Mayo Clinic on Digestive Health SymptomsIf you have indigestion, you may have: Early fullness during a meal.
