Correct answer: E — Screen for dysglycaemia, dyslipidaemia and fatty liver disease

Severe adolescent obesity with acanthosis, hypertension and family history warrants screening for metabolic complications. Endocrine causes of obesity are uncommon when linear growth is not impaired. Random insulin is not a useful diagnostic endpoint; focus is on complications that change management.
