A doctor in clinic

[Unregistered]

I am a doctor seeing a patient with diabetes in clinic. Which way of asking is correct?

How long is your diabetes?
How long do you have diabetes?
How is have you been having diabetes?

Also, which way to inform the patient about the report is correct?

The ultrasound report 'said' your kidney is affected.
The ultrasound report 'says' your kidney is affected.

Thanks!
