The social worker is one of around 15,000 people in the UK with sickle cell disease and she relies on regular blood transfusions to stay alive.
Stephanie has sickle cell anaemia – the most severe form of the condition affecting the red blood cells – and is keen to raise awareness about the disease, which occurs predominantly in people of African and African-Caribbean origin.
