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

284
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
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:
Altered...

Drugs for Treatment of Diarrhea-Predominant IBS

186
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
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: Introduction01:17

Chronic Bowel Disorders: Introduction

459
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

338
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Area of Science:

  • Gastroenterology
  • Psychiatry
  • Computational Biology

Background:

  • Irritable bowel syndrome (IBS) is a complex gut-brain axis disorder.
  • Current IBS classification relies on lower GI symptoms, overlooking psychological and upper GI factors.
  • Existing subgroups may not fully capture IBS heterogeneity.

Purpose of the Study:

  • To redefine IBS subgroups using an unsupervised machine learning algorithm.
  • To incorporate upper GI symptoms and psychological burden into IBS classification.
  • To identify novel, homogeneous IBS clusters.

Main Methods:

  • Applied a mixed-type data clustering algorithm to 988 individuals meeting Rome III IBS criteria.
  • Utilized an unsupervised machine learning approach for subgroup discovery.
  • Analyzed lower GI symptoms, upper GI symptoms, and psychological burden.

Main Results:

  • Identified nine distinct IBS subgroups based on symptom profiles.
  • Discovered new homogeneous clusters beyond traditional Rome subtypes.
  • Subgroups varied in combinations of diarrhea, constipation, upper GI symptoms, and psychological burden.

Conclusions:

  • Machine learning can redefine IBS subgroups by integrating diverse symptom data.
  • New clusters offer a more nuanced understanding of IBS heterogeneity.
  • This approach may improve personalized treatment strategies for IBS patients.
