They are crucial to survival but how much do you know about your kidneys?

Hull and East Yorkshire Hospitals NHS Trust will mark World Kidney Day tomorrow (Thursday, March 8).

Taking place on the same day as International Women’s Day, this year’s event will focus on the link between kidney disease and women’s health.

To mark the global event, we’re showing what it’s like to live with kidney disease, need-to-knows about your kidneys and how to keep them healthy throughout the week.
