When firefighter Tim Hoy developed Type 1 diabetes he was immediately placed on 'light duties' pending a medical dismissal. Tim successfully appealed against the decision, but the assumption that the need for self-treatment with insulin, with its associated risk of hypoglycaemia (low blood sugar levels), poses a safety risk in the workplace is a recurrent problem. The Edinburgh-based study, funded by Diabetes UK, gathered data from over 243 people with diabetes. The main message of the study is that it is inappropriate to restrict people from certain occupations or other aspects of life simply on the basis that they treat their diabetes with insulin.
