Dr Christian Jessen and Dr Dawn Harper are live on Channel 4 for the last time to discuss medical concerns with viewers at home. This time the doctors are joined by a bariatric specialist to discuss weight and obesity issues. Alongside the live cases there are reviews and consumer tests on over-the-counter medicines and insight into popular procedures. And Dr Pixie visits city centres across the UK and drops in on people's homes to offer advice. Live web chats with medical specialists are also hosted over on Channel 4.com/clinic.
