What is functional dyspepsia?

Functional dyspepsia is the medical term for a condition that causes an upset stomach or pain or discomfort in the upper belly. It is a common condition that can affect all age groups. It usually causes a sense of discomfort, and feeling full quickly when eating.

Cause:

It is usually not clear what causes functional dyspepsia. However, the causes may include:

Motor or nerve problems: The process of digesting food involves a series of events involving the nerves and muscles of the digestive tract. Problems in this system can cause the stomach to empty more slowly than normal, causing nausea and vomiting, feeling full quickly when eating, or bloating.
Pain sensitivity: The stomach normally stretches as we eat to hold more food. However, some people are sensitive to this stretching and feel pain. It is not clear why this happens.
Infection: Helicobacter pylori (H. pylori) is a bacterial infection of the stomach that can lead to inflammation (gastritis) or ulcers.
Psychological and social factors: People with functional dyspepsia often have mood problems, like anxiety or depression.
