Irritable Bowel Syndrome I: Introduction

1.4K
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

895
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...

Drugs for Treatment of Diarrhea-Predominant IBS

854
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...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.4K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Area of Science:

  • Gastroenterology
  • Functional Bowel Disorders
  • Human Physiology

Background:

  • Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disease with varying symptom severity.
  • Key risk factors include female sex, younger age, and prior gastrointestinal infections.
  • Diagnosis relies on symptom presentation and exclusion of organic diseases, with treatment focusing on symptom management, diet, and psychotherapy.

Purpose of the Study:

  • To summarize recent progress in understanding functional bowel disorders, specifically IBS.
  • To provide an overview of the current knowledge regarding IBS pathogenesis and management.

Main Methods:

  • Review of current scientific literature and research findings on IBS.
  • Synthesis of information on etiological factors, diagnosis, and therapeutic approaches.

Main Results:

  • IBS pathogenesis involves multifactorial elements including epithelial hyperpermeability, dysbiosis, inflammation, visceral hypersensitivity, genetics, and altered brain-gut interactions.
  • IBS significantly impacts patient quality of life and healthcare systems.
  • Progress has been made in understanding the underlying mechanisms of IBS.

Conclusions:

  • Despite ongoing research, the precise pathogenesis of IBS remains incompletely understood.
  • Continued research is crucial for developing more effective diagnostic tools and targeted therapies for IBS.
  • Comprehensive management strategies are essential for improving the lives of individuals with IBS.
