Information Living with thyroid disorders Transition from paediatric to adult care Transition is the process of getting ready to be looked after by adult doctors (endocrinologists and GPs) when you’ve previously been looked after by specialist children’s doctors (paediatricians). It is a time when you, rather than your parents or carers, begin to take control of managing your thyroid condition. If you have hypothyroidism it will probably mean you no longer need to go to hospital appointments and your care will be managed by your GP. This change should happen when you are well, and at a time which fits in with you. You may want to plan a time which is, for example, not too close to exams, leaving school or college, going to university and starting a new job. Transition will usually happen between 16 and 19 years of age. If you have any questions or are worried about how the change in your care will happen you should ask one of the doctors or nurses to explain how the process will work and what will mean for you.
