    Study Notes

    Gastrointestinal (GI) Disorders

    • Diarrhea: Increased frequency of bowel movements with increased fluid content.
    • Acute Non-inflammatory Diarrhea (Large-Volume): Bacterial toxins disrupt normal absorption, leading to excessive water loss. Examples include Vibrio cholera and Norwalk virus.
    • Chronic Diarrhea: Can be osmotic (excess fluid drawn into the lumen by poorly absorbed solutes) or secretory (excessive secretion of fluids by intestinal mucosa). Chronic issues can include tumors.
    • Gastritis: Inflammation of the stomach lining.
      • Acute Gastritis: Transient inflammation caused by irritants like NSAIDs, alcohol, and bacterial toxins.
      • Chronic Gastritis: More persistent inflammation which can be classified as Type A (immune-mediated, rare) and Type B (non-immune, common).
    • Inflammatory Bowel Disease: Chronic inflammatory disorders.
      • Crohn's Disease: Affects the entire GI tract, with inflammation beginning in the lymph tissue, potentially extending through the bowel wall. Lesions "skip" around, are surrounded by inflamed/thickened tissue, creating a cobblestone appearance. Fistulas (abnormal connections) and abscesses can form. Most common in the ileum.
      • Ulcerative Colitis: ULC, begins in the rectum and progresses through the colon. Inflammation forms in the crypts of Lieberkuhn, causing ulcerations initially in the rectum/sigmoid colon, progressing to entire colon. Inflammation characterized by hemorrhage/lesions.
    • Peptic Ulcer Disease (PUD):
      • Duodenal PUD: Pain during periods of emptiness (2-3 hrs after eating).
      • Gastric PUD: Pain during and after eating.
    • Diverticulitis: Inflammation of small pouches (diverticula) in the colon, often related to low fiber diets and/or constipation.

    Other GI Disorders

    • Gastroesophageal Reflux Disease (GERD): Backward flow of stomach contents into the esophagus due to transient lower esophageal sphincter (LES) relaxation or weakness. Leads to heartburn and reflux.
    • Liver Dysfunction: Conditions affecting liver function affecting bilirubin metabolism which potentially results in Jaundice, hepatic encephalopathy, ascites, portal hypertension, and hepatorenal syndrome.

    Additional GI/Renal Information

    • Kidney Stones: Formation due to supersaturated urine and/or lack of inhibitors. Causes pain, hematuria, obstruction.
    • Urinary Tract Infections (UTIs): Infections in the urinary system, often caused by E. coli, Proteus, or Pseudomonas. Can be complicated by infection or obstruction or simple.
    • Acute Kidney Injury (AKI): Sudden decrease in kidney function categorized into prerenal, intrarenal, and postrenal causes.
    • Chronic Kidney Disease (CKD): Gradual loss of kidney function resulting in systemic manifestations.
    • Hepatitis: Inflammation of the liver. Different types, characterized by specific stages (preicteric, icteric, posticteric).
    • Cirrhosis: Diffuse scarring and nodular regeneration of liver structure impacting many functions.

    Other Information in the Text

    • Cancer Staging: Cancer is categorized by grading (0-IV) based on tumor (T), node (N), and metastasis (M).
