bbc.co.uk/health includes links to health-related websites outside the BBC. These links are provided to offer users further relevant information, which they may wish to explore.

The BBC is not responsible for the content of external websites. The inclusion of a link to a third party website from the BBC Health pages should not be understood as an endorsement.

How we choose our links

BBC Health has sought to include links to relevant organisations that our readers may find useful in exploring the breadth of treatment and care options available.

External sites that BBC Health links to should carry transparent information about their funding sources and commercial interests including sponsorship arrangements and we recommend that users familiarise themselves with this information when they visit external sites (often via the 'about us' or similar section), and discuss their own treatment options with their GP.

We do not normally link to sites which are not free to access.

We do not link to external sites in return for cash, services or any other consideration in kind.

The external links on the BBC Health site are reviewed and varied on an ongoing basis, according to editorial relevance.

If you wish to submit a link for consideration, please use our Feedback page.
