Irritable Bowel Syndrome (IBS) involves abnormal gut motility, gas, and pain sensitivity. Immune system dysfunction and altered enteric nervous system signaling are key factors in IBS pathogenesis.
Area of Science:
- Gastroenterology
- Neurogastroenterology
- Immunology
Background:
- Irritable Bowel Syndrome (IBS) is a complex functional gastrointestinal disorder.
- Symptoms include chronic abdominal discomfort and altered bowel habits without identifiable organic causes.
- Recent research highlights novel insights into IBS pathogenesis.
Purpose of the Study:
- To review recent findings on the pathogenesis of Irritable Bowel Syndrome (IBS).
- To explore the roles of abnormal intestinal motility, gas production, and visceral hypersensitivity.
- To examine the involvement of the enteric nervous system (ENS) and immune system in IBS.
Main Methods:
- Literature review of recent scientific findings.
- Analysis of studies investigating the enteric nervous system (ENS) in IBS.
- Examination of research on immune system alterations and inflammation in IBS patients.
Main Results:
- Dysfunction of the enteric nervous system (ENS) is implicated, with altered expression of receptors like TRPV1, ASIC3, P2X3r, TTRX2, and PPARs.
- The immune system shows altered cellular composition and activation in IBS subjects.
- Inflammation and immune dysregulation impact nerve fiber sensitivity.
Conclusions:
- Abnormal intestinal motility, gas production, and enhanced nociception are key mechanisms in IBS.
- Enteric nervous system (ENS) dysfunction, evidenced by altered receptor expression, plays a significant role.
- Immune system impairment and inflammation are critical factors influencing IBS symptoms and warrant further therapeutic development.

Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:
Irritable Bowel Syndrome I: Introduction
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Drugs for Treatment of Diarrhea-Predominant IBS
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
