Health passport 

The National Autistic Society has created a health passport which you can complete by printing and writing on it or typing in responses. The passport is designed to help autistic people to communicate their needs to doctors, nurses and other healthcare professionals, and can be taken with you for appointments and you can ask for it to be kept with your patient notes if you are admitted to hospital: https://www.autism.org.uk/advice-and-guidance/physical-health/my-health-passport
