When I met Sonia Carrasco, 14 years ago, she was suffering from diabetes ketoacidosis – extremely high glucose levels, a sign of poorly controlled diabetes. Although she had been living with the condition for about 6 years, her diabetes knowledge was minimal, reflecting a general lack of health awareness. When I asked Sonia to describe her feelings the day she was given a diagnosis of type 1 diabetes, 20 years before, she recalls an experience made all the more terrifying by an acute fear of the unknown. She had understood that she had leukaemia.
