Indigestion

Definition & Facts of Indigestion

What is indigestion?

Indigestion, also called dyspepsia or upset stomach, is a general term that describes a group of gastrointestinal symptoms that occur together. These symptoms most often include

• pain, a burning feeling, or discomfort in your upper abdomen
• feeling full too soon while eating a meal
• feeling uncomfortably full after eating a meal

Indigestion may be

• occasional—happening once in a while
• chronic—happening regularly for a few weeks or months
• functional—having chronic symptoms without a specific cause
• Indigestion is not a disease. However, indigestion may be a sign of certain digestive tract diseases or conditions. Indigestion is not always related to eating.

Sometimes digestive tract diseases such as peptic ulcer disease, gastritis, and stomach cancer  cause chronic indigestion. However, most often doctors do not know what causes chronic indigestion. Chronic indigestion without a health problem or digestive tract disease that could explain symptoms is called functional dyspepsia.

Indigestion is a common condition, affecting about 1 in 4 people in the United States each year.1

Of those people with indigestion who see a doctor, almost 3 in 4 are diagnosed with functional dyspepsia.2
