A few topics that might be helpful/relevant:
- How do deal with diabetes in various social situations (i.e., hanging out with friends, parties, alcohol, etc). I think there are lots of situations that diabetes can be a pretty big deal but for which parents and endos don't really prepare kids.
- How to deal with diabetes on the job. The teenage years are when many kids start their first job. They will need to know their rights as well as how to handle diabetes in a way that minimizes the impact on whatever they chose to do.
- How to take an active role in your own health care. The teen years are a weird time for diabetes. Many kids are starting to really transition into caring for their diabetes "full time." But some don't yet have the knowledge about how to do things like schedule doctors' appointments, deal with insurance, or refill prescriptions.
These are just some practical/functional topics that teens might find helpful. But I agree with others that having the teens suggest topics would also be good.
