Chronic constipation: no more idiopathic, but a true neuropathological entity

Area of Science:

• Gastroenterology
• Neuroscience
• Cell Biology

Background:

• Chronic constipation is often classified as a functional or idiopathic disorder.
• Emerging evidence suggests underlying pathophysiological mechanisms.
• These mechanisms may involve complex abnormalities within the enteric nervous system.

Purpose of the Study:

• To review the evidence linking enteric nervous system abnormalities to chronic constipation.
• To explore the role of enteric glial cells in the pathophysiology of constipation.
• To propose a reclassification of certain constipation forms as neuro-gliopathies.

Main Methods:

• Literature review of recent studies on chronic constipation and the enteric nervous system.
• Analysis of research focusing on enteric glial cell function in constipated individuals.
• Synthesis of findings to support the neuro-gliopathy hypothesis.

Main Results:

• Abnormalities in the enteric nervous system are increasingly recognized as a cause of chronic constipation.
• Enteric glial cells show consistent involvement in patients with constipation.
• These findings challenge the traditional view of constipation as purely functional.

Conclusions:

• Chronic constipation may be rooted in neuro-glial dysfunction.
• Certain forms of constipation should be considered neuro-gliopathies.
• Further research into the enteric nervous system is crucial for understanding and treating constipation.
