Functional dyspepsia (dis-PEP-see-uh) is a term for recurring signs and symptoms of indigestion that have no obvious cause. Functional dyspepsia is also called nonulcer stomach pain or nonulcer dyspepsia.
Functional dyspepsia is common and can be long lasting. The condition can cause signs and symptoms that resemble those of an ulcer, such as pain or discomfort in your upper abdomen, often accompanied by bloating, belching and nausea.
Signs and symptoms of functional dyspepsia may include:
- A burning sensation or discomfort in your upper abdomen or lower chest, sometimes relieved by food or antacids
- An early feeling of fullness when eating
When to see a doctor
Make an appointment with your doctor if you experience persistent signs and symptoms that worry you.
Seek immediate medical attention if you experience:
- Bloody vomit
- Dark, tarry stools
- Shortness of breath
- Pain that radiates to your jaw, neck or arm
- Unexplained weight loss
It's not clear what causes functional dyspepsia. Doctors consider it a functional disorder, which means it's not found to be caused by a specific disease or diagnosable disorder.
Factors that can increase the risk of functional dyspepsia include:
- Female sex
- Older age
- Use of certain over-the-counter pain relievers, such as aspirin and ibuprofen (Advil, Motrin IB, others), which can cause stomach problems
- Anxiety or depression
- History of childhood physical or sexual abuse
