Scenario

Emily Dawson, a 34-year-old vegetarian female, presents with fatigue, dizziness, and hair thinning over the past 3 months.

She has noticed poor concentration, brittle nails, and occasional mouth ulcers.

She follows a vegetarian diet but is unsure if she is getting enough vitamins and iron.

She has regular but heavy periods and has been training intensely for a marathon.

She denies weight loss, gastrointestinal symptoms, or neurological complaints.

On examination:

  • General appearance: Alert but slightly pale
  • Blood pressure: 110/70 mmHg
  • Heart rate: 84 bpm
  • Conjunctiva: Mild pallor
  • Nails: Brittle with mild koilonychia
  • Oral cavity: Small aphthous ulcer on lower lip
  • Neurological exam: No sensory or motor deficits

Likely Diagnosis: Iron Deficiency Anaemia, Possibly B12 Deficiency

Examiner Only Information

THE COMPETENT CANDIDATE

The competent candidate should be able to:

Q1: What key aspects of Emily’s history and examination suggest a vitamin or nutritional deficiency?

The competent candidate should:

  • Symptoms suggestive of iron or B12 deficiency:
    • Fatigue, dizziness, poor concentration – common in both deficiencies.
    • Hair thinning, brittle nails, and mouth ulcers – features of iron and B12 deficiency.
  • Risk factors:
    • Vegetarian diet for 5 years, increasing the risk of iron, B12, and zinc deficiency.
    • Heavy menstrual periods, contributing to iron loss.
    • High-intensity endurance training, increasing iron demand.
  • Examination findings supporting deficiency:
    • Mild conjunctival pallor – suggestive of iron deficiency anaemia.
    • Brittle nails with mild koilonychia – seen in iron deficiency.
    • Aphthous ulcer in oral cavity – could indicate B12 deficiency.

Q2: What investigations would you order to confirm the suspected deficiencies?

The competent candidate should:

  • Essential blood tests:
    • Full blood count (FBC) – to assess for microcytic anaemia (iron deficiency) or macrocytic anaemia (B12/folate deficiency).
    • Iron studies – ferritin, serum iron, transferrin saturation (low ferritin suggests iron deficiency).
    • Vitamin B12 and folate levels – to rule out B12/folate deficiency.
  • Additional tests if clinically indicated:
    • Thyroid function tests (TFTs) – if fatigue persists despite correction of deficiencies.
    • Coeliac serology – if malabsorption is suspected (family history of iron deficiency anaemia).

Q3: What is the appropriate management plan for Emily’s nutritional deficiency?

The competent candidate should:

  • Iron deficiency management:
    • Oral iron supplementation (ferrous sulfate 325 mg every second day).
    • Take with vitamin C for better absorption; avoid tea/coffee around the time of ingestion.
  • B12 deficiency (if present):
    • Oral cyanocobalamin or intramuscular B12 injections (if severe deficiency).
  • Monitoring and follow-up:
    • Repeat FBC and iron studies in 6-8 weeks to assess response.
    • Monitor for gastrointestinal side effects from iron supplements.

Q4: How would you educate Emily about optimising her vegetarian diet to prevent future deficiencies?

The competent candidate should:

  • Iron sources for vegetarians:
    • Legumes, tofu, dark leafy greens, fortified cereals, nuts, and seeds.
    • Pair iron-rich foods with vitamin C (citrus, tomatoes) to improve absorption.
  • B12 sources:
    • Eggs, dairy, fortified cereals, and nutritional yeast.
    • Consider B12 supplementation if dietary intake is insufficient.
  • General dietary balance:
    • Ensure adequate protein intake (legumes, dairy, eggs).
    • Monitor calcium and vitamin D levels due to potential low intake.

Q5: When would you consider specialist referral in this case?

The competent candidate should:

  • Referral to a gastroenterologist if:
    • Iron or B12 deficiency does not improve despite supplementation.
    • Coeliac disease or inflammatory bowel disease is suspected.
  • Referral to a dietitian if:
    • Emily needs guidance on balancing her vegetarian diet.
    • Persistent symptoms despite optimising nutritional intake.

SUMMARY OF A COMPETENT ANSWER

  • Recognises symptoms and risk factors for iron and B12 deficiency.
  • Orders appropriate investigations, including FBC, iron studies, B12, and folate.
  • Provides evidence-based supplementation and follow-up.
  • Educates the patient on optimising vegetarian nutrition.
  • Identifies when referral to a specialist is necessary.

PITFALLS

  • Failing to consider B12 deficiency in a vegetarian patient.
  • Overlooking the impact of heavy menstrual bleeding on iron levels.
  • Not addressing dietary modifications alongside supplementation.
  • Missing an underlying cause such as coeliac disease.
