The causes of functional indigestion are as follows:
- Psychoemotional stressful situations (acute and chronic).
- Alimentary disorders: irregular eating, changing diet, overeating, abuse of carbohydrates, coarse plant fiber, acute and irritating gastric mucosa.
- Food allergy.
- Smoking, alcohol abuse.
- Exogenous factors - high air temperature, high atmospheric pressure, vibration, ionizing radiation, burns, gastrointestinal drugs (NSAIDs, glucocorticoids, etc.).
- Diseases of other organs and systems (nervous, endocrine, cardiovascular, respiratory, genitourinary, hematopoietic), as well as diseases of the digestive system (liver, biliary tract, pancreas, intestines).
These etiological factors cause disorders of motor and secretory functions of the stomach, gastric blood flow. A certain pathogenetic role may play a violation of the function of the gastrointestinal endocrine system.
