Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

GI / HEPATOBILIARY DISEASE

YEAR 2 | PAGE 23F - INTESTINAL, PANCREATIC, LIVER + BLEEDING SYNDROMES

LOCALIZE THE SYNDROME BEFORE NAMING THE DISEASE

Use SITE -> PATHOLOGIC PROCESS -> SYMPTOM / LAB PATTERN -> TEST -> TREATMENT. Separate luminal/mucosal disease from pancreas/biliary disease, hepatocellular injury from cholestasis, and upper from lower GI bleeding.

B. CLINICAL GI / LIVER VIDEOS - CORE + INTEGRATION — DISEASE-INTEGRATION CHECK

  • Dysphagia/abdominal pain/diarrhea/bleeding: localize by symptom timing, stool pattern, hemodynamics and red flags before selecting a test.
  • Liver: distinguish hepatocellular injury, cholestasis and synthetic dysfunction; connect bilirubin pattern to prehepatic/hepatic/posthepatic mechanisms.
  • Pancreas/biliary: use pain pattern, enzymes and imaging to separate pancreatitis, biliary obstruction and related complications.
  • Nutrition: connect disease site to expected vitamin/mineral deficiency, weight loss, steatorrhea or refeeding risk. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
