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

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

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 colonic...

Irritable Bowel Syndrome III: Medical and Nursing Management

Irritable Bowel Syndrome III: Medical and Nursing Management

Managing Irritable Bowel Syndrome (IBS) involves a multifaceted approach, including lifestyle modifications, dietary changes, and medication.

Irritable Bowel Syndrome I: Introduction

Irritable Bowel Syndrome I: Introduction

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...

Irritable Bowel Syndrome

DefinitionIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent combinations of abdominal pain, bloating, diarrhea, or constipation.Pathophysiology of irritable bowel syndromeIts pathophysiology is multifactorial, involving disturbances in motility, sensory processing, microbial balance, barrier integrity, and gut–brain communication. These mechanisms interact to produce symptoms that vary across IBS subtypes.Altered Motility PatternsDisordered...

Drugs for Treatment of Constipation-Predominant IBS

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs for Treatment of Diarrhea-Predominant IBS

Drugs for Treatment of Diarrhea-Predominant IBS

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...

Summary

For irritable bowel syndrome (IBS) management, a balanced diet is recommended. While exclusion diets are generally not useful, probiotics and psyllium show promise for IBS symptom relief.

Area of Science:

Gastroenterology
Nutritional Science
Microbiome Research

Background:

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder.
Dietary interventions are frequently explored for IBS management.
The role of probiotics and prebiotics in IBS is an area of active research.

Purpose of the Study:

To review the evidence supporting dietary manipulations for irritable bowel syndrome (IBS).
To assess the efficacy of probiotics, prebiotics, and specific diets in IBS management.

Main Methods:

Literature review of studies on dietary interventions in IBS.
Meta-analysis of available evidence on probiotic use in IBS.
Evaluation of exclusion diets, very low carbohydrate diets (VLCD), and fiber supplementation.

Main Results:

Exclusion diets are generally not beneficial for IBS, except for specific malabsorbed sugars.
Very low carbohydrate diets (VLCD) show preliminary promise but require further safety evaluation.
Psyllium and probiotics demonstrate growing evidence of effectiveness in managing IBS symptoms.

Conclusions:

Most IBS patients benefit from a balanced diet without unnecessary restrictions.
Hydrophilic colloids like psyllium are preferred over general fiber increase.
Probiotics show increasing evidence of efficacy for IBS management.
