Blood sugar in Portsmouth.

Diabetes recorded by GPs in Portsmouth, alongside a separate estimate of diagnosed and undiagnosed type 2 diabetes.

Plain-English context

7.6% of patients aged 17 and over registered at GP practices in Portsmouth had diagnosed diabetes in 2024/25. This includes both type 1 and type 2 diabetes. A separate model estimates that 7.1% of residents aged 16 and over had type 2 diabetes, diagnosed or undiagnosed, in 2021. These figures use different years, ages, populations and diabetes types. Their difference is not a measure of undiagnosed diabetes. GP-register prevalence is not age-adjusted and depends on case-finding.
