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.
If you have indigestion, you may have:
Early fullness during a meal. You haven't eaten much of your meal, but you already feel full and may not be able to finish eating.
Uncomfortable fullness after a meal. The feeling of fullness lasts longer than it should.
Discomfort in the upper abdomen. You feel a mild to severe pain in the area between the bottom of your breastbone and your bellybutton.
Burning in the upper abdomen. You feel an uncomfortable heat or burning sensation between the bottom of your breastbone and your bellybutton.
Bloating in the upper abdomen. You feel an uncomfortable sensation of tightness in your upper abdomen.
Nausea. You feel as if you want to vomit.
