Is it worth it?
This page does not answer that. Here is what the NHS does for free, and what those who set screening policy say.
- NHS Health Check
- “a free check-up of the health of your heart and blood vessels”
- Who can have it
- People “aged 40 to 74 who do not have” certain conditions, such as heart disease or diabetes, or who already take medicines like statins
- How often
- Every 5 years, by invitation from your GP or local council
- What it checks
- Height, weight, waist, blood pressure, cholesterol and possibly blood sugar, in about 20 to 30 minutes
