Other Disorders of Digestive System

1.7K
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...

Inflammatory Bowel Disease II: Crohn's Disease

1.5K
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...

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

1.0K
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...

Gastritis-II: Pathophysiology

1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

896
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 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...

    Summary

    Celiac disease affects about 1% of the population, often remaining undiagnosed. Early diagnosis and a strict gluten-free diet are crucial for managing this autoimmune disorder and preventing serious complications.

    Area of Science:

    • Gastroenterology
    • Immunology
    • Genetics

    Background:

    • Celiac disease prevalence is ~1% globally, with many cases undiagnosed.
    • Clinical symptoms range from malabsorption to silent or extra-intestinal manifestations.

    Purpose of the Study:

    • To outline diagnostic approaches for celiac disease.
    • To detail current treatment strategies and long-term monitoring protocols.
    • To discuss potential future therapeutic developments.

    Main Methods:

    • Serological testing with high sensitivity and specificity.
    • Confirmation via biopsy in adults.
    • HLA typing and gluten challenge for those on a gluten-free diet.

    Main Results:

    • Diagnosis relies on serology and biopsy, with specific protocols for individuals already adhering to a gluten-free diet.
    • Gluten-free diet is the primary treatment, requiring nutritionist supervision.
    • Monitoring involves regular serology and periodic histology.

    Conclusions:

    • Effective management of celiac disease hinges on accurate diagnosis and strict adherence to a gluten-free diet.
    • Long-term monitoring is essential to detect poor disease control and prevent complications like lymphoma.
    • Emerging pharmacologic therapies may offer future treatment options.
