Recent insights into digestive motility in functional dyspepsia

Area of Science:

• Gastroenterology
• Neurogastroenterology
• Digestive Physiology

Background:

• Functional dyspepsia (FD) is a common gastrointestinal disorder characterized by upper abdominal pain of unknown origin.
• Pathophysiology remains unclear, but altered gastric motility and visceral sensation are key areas of interest.
• Potential contributing factors include neurohormonal dysfunction, autonomic issues, hypersensitivity, infections, and psychosocial elements.

Purpose of the Study:

• To review recent research on the pathophysiology of functional dyspepsia.
• To discuss emerging and established treatment options for FD, focusing on digestive dysmotility.

Main Methods:

• Literature review of recent studies on FD pathophysiology and treatment.
• Analysis of evidence for various therapeutic agents and modalities.

Main Results:

• Growing interest in impaired gastric accommodation and emptying in FD.
• Prokinetic agents like itopride and mosapride show therapeutic efficacy in controlled studies.
• New treatments include sensorimotor receptor modulators, nitrergic pathway activation, kampo medicine, acupuncture, and gastric electrical stimulation.

Conclusions:

• Digestive dysmotility is a significant factor in functional dyspepsia.
• While established treatments exist, novel therapeutic approaches are emerging for FD management.
