Summary

Functional dyspepsia (FD) involves upper abdominal pain with unclear causes. Recent research highlights new mechanisms like gut-brain axis and infection, guiding future treatments for this common condition.

Area of Science:

  • Gastroenterology
  • Digestive Physiology

Background:

  • Functional dyspepsia (FD) presents as unexplained upper abdominal pain, a common challenge in gastroenterology.
  • Traditional theories implicate delayed gastric emptying, visceral hypersensitivity, and impaired gastric accommodation.
  • The relationship between FD and irritable bowel syndrome remains uncertain.

Purpose of the Study:

  • To review traditional and recent advances in the pathophysiology of functional dyspepsia.
  • To explore potential novel therapeutic opportunities for FD based on emerging mechanisms.

Main Methods:

  • Literature review of traditional knowledge and recent research on FD pathophysiology.
  • Analysis of studies focusing on postprandial motor disturbances and neurohormonal alterations.

Main Results:

  • Recent FD research emphasizes postprandial motor disturbances (e.g., accelerated gastric emptying, incoordination) and altered meal-induced neurohormonal responses.
  • Previous acute infection is also considered a factor in FD development.
  • Current therapeutic options for FD are limited, necessitating exploration of new mechanisms.

Conclusions:

  • Novel therapeutic strategies for FD include prokinetics, gastric accommodation modulators, visceral analgesics, and agents targeting neurohormonal responses.
  • Understanding advanced pathophysiologic mechanisms is key to developing effective FD treatments.
