Anatomy of the Intestines01:23

Anatomy of the Intestines

89.4K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

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

998
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...

Other Disorders of Digestive System

1.6K
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

871
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...

Irritable Bowel Syndrome I: Introduction

1.3K
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...

Inflammatory Bowel Disease II: Crohn's Disease

1.4K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Summary

Altered gut microbiota (dysbiosis) may trigger celiac disease (CD) by increasing inflammation. Probiotic use in CD shows promise for reducing inflammation and improving symptoms, though more research is needed.

Area of Science:

  • Gastroenterology
  • Immunology
  • Microbiome Research

Background:

  • Celiac disease (CD) is an autoimmune enteropathy caused by gliadin in genetically susceptible individuals.
  • The role of human intestinal microbiota in CD pathogenesis and clinical course is increasingly recognized.
  • Dysbiosis, an imbalance in gut bacteria, is a potential contributing factor to CD.

Purpose of the Study:

  • To review microbiota alterations in CD.
  • To analyze the influence of these alterations on CD pathogenesis.
  • To explore potential applications of microbiota modulation in managing CD.

Main Methods:

  • Review of current literature on celiac disease and intestinal microbiota.
  • Analysis of studies detailing microbial composition changes in CD patients.
  • Examination of research on the immunomodulatory effects of microbiota and probiotics.

Main Results:

  • Dysbiosis in CD is characterized by increased gram-negative/Bacteroidetes and decreased Bifidobacteria/Lactobacilli.
  • An unfavorable microbiota may exacerbate the immune response to gliadin.
  • Probiotic administration may reduce pro-inflammatory cytokines and mucosal inflammation in CD.

Conclusions:

  • Dysbiosis is a potential trigger for celiac disease, alongside genetic and environmental factors.
  • Probiotic administration shows potential for improving CD symptoms and reducing inflammation.
  • Further research is needed to establish a strong pathophysiological basis for probiotic use in CD.
