    Study Notes

    IBS (Irritable Bowel Syndrome)

    • Key pathophysiological feature: Visceral hypersensitivity
    • IBS subtypes:
      • IBS-D (predominantly loose, watery stools)
      • IBS-C (predominantly constipation)
      • IBS-M (mixed bowel habits)
      • IBS-U (unspecified)
    • Altered gut-brain axis: Dysregulated communication between the central nervous system (CNS) and enteric nervous system (ENS) is a primary factor.
    • Common age of diagnosis: Late teens to early 40s
    • Dietary management: Low FODMAP diet is recommended.
    • Soluble fiber role: Improves stool consistency.
    • Stress-related symptom reduction: Cognitive behavioral therapy (CBT) is an effective non-pharmacological therapy.
    • First-line pharmacotherapy for abdominal pain: Dicyclomine

    IBD (Inflammatory Bowel Disease)

    • Differentiating features:
      • Crohn's disease: Characterized by discontinuous inflammation, often with skip lesions, and can involve any part of the GI tract. A hallmark finding is fistulas.
      • Ulcerative colitis: Presents with continuous inflammation, typically confined to the colon and rectum. A hallmark finding is continuous mucosal inflammation
    • Crohn's Disease:
      • Severe Crohn's disease induction of remission: Anti-TNF agents are the cornerstone.
      • Mild-to-moderate Crohn's disease therapy: Budesonide (corticosteroid)
      • Methotrexate black box warning: Bone marrow suppression
    • Ulcerative colitis:
      • Mild-to-moderate UC first-line therapy: Sulfasalazine
    • Sulfasalazine mechanism: Splits into 5-aminosalicylic acid (5-ASA) and sulfapyridine.
    • Azathioprine adverse effects: Pancreatitis
    • IBD complication specific to Ulcerative colitis: Toxic megacolon
    • Primary therapeutic goal: Preventing relapse and maintaining remission
    • Immune cell migration blocking agents in IBD: Anti-integrin agents (e.g., vedolizumab)
    • Probiotics benefit in IBS: Reduction of abdominal pain and bloating
