Ms Adebayo, a 26-year-old patient, presents with a complaint of feeling constantly tired. She believes this has been happening gradually over the past few months and has no other specific physical symptoms. She is currently taking the combined oral contraceptive pill, a non-smoker, and reports drinking a bottle of wine per week. Ms Adebayo has a family history of thyroid disease and wonders if she is developing a thyroid problem. She also mentions that she has been a vegan for a couple of years and asks if this could be related.

After conducting various blood tests, an abnormal full blood count was discovered:

Hb 91 g/L Male: (135-180) Female: (115 – 160)
Platelets 220 * 109/L (150 – 400)
WBC 6.7 * 109/L (4.0 – 11.0)
MCV 109 fL (80-100)

What is the likely underlying cause of Ms Adebayo’s fatigue?
