Annie - I'm sorry you've tipped over the line, but on the upside, at least you know the sorts of things we need to do.
Sitting in front of me is a letter entitled "First Invite Letter", which begins with:
"Dear X
NHS health checks are now being offered to people aged between 40 and 74 once every 5 years......"
So, it appears in my part of England, at least, these routine checks are being offered. As
@Avocado Sevenfold says, people can only enjoy the benefit of these checks if they take up the invitation.
Good luck with your T2 journey.
