Eating Too Fast Is One of the Top Causes of Indigestion

Functional dyspepsia — indigestion with no detectable organic cause — accounts for roughly 70% of all indigestion cases. Its true cause remains poorly understood and is often linked to increased nerve sensitivity in the stomach.

Heartburn, a symptom of indigestion, can produce chest pain that radiates to the arm — identical to a cardiac event. This similarity causes thousands of unnecessary emergency room visits every year.

Fizzy drinks release carbon dioxide gas inside the stomach, expanding it and causing bloating, belching, and indigestion — especially when consumed quickly or on an empty stomach.

Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the enzymes that protect the stomach lining, making them one of the leading pharmaceutical causes of indigestion, gastritis, and peptic ulcers worldwide.
