Inflammatory Bowel Disease IV: Pharmacological Management
127
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
331
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...

Irritable Bowel Syndrome I: Introduction
272
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:
