Correct answer: E — Menstrual blood loss

Heavy menstrual bleeding is the most common cause of iron deficiency anaemia in adolescent females. Assessment should include menstrual history (cycle length, duration, flow), dietary iron intake, and screening for underlying gynaecological or haematological conditions. Treatment includes iron supplementation and management of heavy periods (COCP, tranexamic acid, or NSAID).
