Gastro: 25 Practice MCQs (MRCP Part 1)

TL;DR

Gastroenterology is a high-yield area in MRCP Part 1, with frequent questions on liver function tests, IBD, GI bleeding, and pancreatitis. This guide to Gastro: 25 Practice MCQs (MRCP Part 1) outlines the most tested topics, key exam traps, and a practical approach to solving MCQs. Focus on pattern recognition, guideline-based management, and consistent practice using question banks and mocks.


Why this matters

Gastroenterology forms a core component of the MRCP Part 1 exam, typically accounting for 10–15% of questions. The exam emphasises clinical reasoning—interpreting biochemical patterns, recognising disease presentations, and selecting the most appropriate next step.

Success in this section depends less on memorising facts and more on identifying patterns quickly and accurately.

To build a structured approach, start with the official MRCP(UK) exam overview:👉 https://www.mrcpuk.org/mrcpuk-examinations/part-1


Core high-yield gastro topics

1. Liver function tests (LFTs)

  • Hepatocellular pattern: ↑ALT, ↑AST

  • Cholestatic pattern: ↑ALP, ↑GGT

  • Isolated bilirubin: consider Gilbert syndrome

2. Inflammatory bowel disease (IBD)

  • Ulcerative colitis: continuous inflammation, rectal involvement

  • Crohn’s disease: skip lesions, fistulae

3. Upper gastrointestinal bleeding

  • Haematemesis vs melaena

  • Initial management: ABC → IV access → resuscitation

  • Use of scoring systems (e.g. Glasgow-Blatchford)

4. Chronic liver disease

  • Ascites, varices, encephalopathy

  • Child-Pugh classification

  • Portal hypertension complications

5. Pancreatitis

  • Causes: gallstones, alcohol

  • Diagnosis: amylase/lipase ≥3× normal

  • Management: aggressive IV fluids

High-yield facts for rapid recall

  1. AST:ALT ratio >2 → alcoholic liver disease

  2. ALT > AST → viral hepatitis

  3. Raised ALP + GGT → cholestasis

  4. Anti-mitochondrial antibodies → primary biliary cholangitis

  5. Anti-smooth muscle antibodies → autoimmune hepatitis

  6. SAAG ≥11 g/L → portal hypertension

  7. Bloody diarrhoea → ulcerative colitis

  8. Perianal disease → Crohn’s

  9. Lipase more specific than amylase

  10. Terlipressin reduces mortality in variceal bleeding

How MRCP frames gastro MCQs

Most questions test decision-making, not just diagnosis.

Common stems include:

  • “What is the most appropriate next investigation?”

  • “What is the initial management?”

  • “What is the most likely diagnosis?”

Practising under timed conditions is essential. Use a reliable Qbank such as:👉 https://passmedicine.com/mrcp/


Practical example (Mini-MCQ)

A 52-year-old man presents with jaundice. Blood tests show:

  • AST: significantly elevated

  • ALT: mildly elevated

  • AST:ALT ratio = 2:1

  • GGT elevated

What is the most likely diagnosis?

A. Viral hepatitisB. Alcoholic liver diseaseC. Autoimmune hepatitisD. Primary biliary cholangitis

Answer: B. Alcoholic liver disease

Explanation: An AST:ALT ratio greater than 2 is highly suggestive of alcohol-related liver disease. Elevated GGT further supports this diagnosis.

Practical study checklist

  • Revise LFT interpretation daily

  • Memorise key antibody associations

  • Practise 20–30 MCQs daily

  • Focus on “next best step” questions

  • Review explanations thoroughly

  • Use spaced repetition techniques

  • Attempt weekly timed mocks

  • Integrate topics (e.g. liver + haematology)

Common pitfalls

  • Confusing Crohn’s disease with ulcerative colitis

  • Ignoring AST:ALT ratio in liver questions

  • Missing GGT as a clue to alcohol use

  • Jumping to diagnosis without answering the actual question

  • Misinterpreting isolated ALP elevation


FAQs

1. How many gastro questions come in MRCP Part 1?

Around 10–15% of questions are gastroenterology-based, with hepatology forming a significant proportion.

2. What are the most important gastro topics?

LFT interpretation, IBD, GI bleeding, chronic liver disease, and pancreatitis are the highest yield.

3. Are NICE guidelines important for MRCP Part 1?

Yes, especially for management decisions in GI bleeding and liver disease. Familiarity with guideline-based care is essential.

4. How can I improve accuracy in MCQs?

Practise regularly, analyse mistakes, and focus on understanding patterns rather than memorising isolated facts.

5. Is hepatology more important than general gastro?

Yes. Liver-related questions are more frequently tested and often require interpretation-based reasoning.
