10 facts
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.
Lying down immediately after a meal slows gastric emptying and removes the gravitational support that helps food move downward, significantly increasing the risk of acid reflux and indigestion.
Helicobacter pylori infects about half the world's population and is the leading cause of chronic peptic ulcers. Discovered in 1982, the finding earned Barry Marshall and Robin Warren the 2005 Nobel Prize in Medicine.
The gut-brain axis directly links emotions to digestion. Stress and anxiety can slow or disrupt the digestive process, making indigestion one of the most common physical symptoms of mental stress.
Eating too quickly is one of the leading triggers of indigestion. The brain takes about 20 minutes to receive satiety signals from the stomach, so fast eating leads to overfilling and digestive distress.
The stomach secretes 1.5 to 2 liters of hydrochloric acid daily to digest food. The stomach lining constantly renews itself to prevent being dissolved by its own acid.
Dyspepsia affects an estimated 40% of people worldwide at some point in their lives, making it one of the most common gastrointestinal complaints globally.
