Join the doctors for a special episode as they revisit with Ouchers from across the last seven series to find out how they are doing now. We revisit Matthew, who had a cochlear implant enabling him to hear four years ago, as well as Ouch Patients Ruby and Bolu, to see how their leukemia and sickle cell anemia treatments are going. We find out if Declan made it back to diving competitions after breaking his leg a year ago and discover how much taller David has grown thanks to his ilizarov frame.

In this special episode, the doctors investigate food and poo to show you why it is important to know what you are eating and look after your body! They reveal how much hidden sugar is in your dinner, find out what is good and bad about fat and discover what your poo can tell you about your general health! Two teams of Ouchers take on the challenge to design a new cereal box to show the part packaging plays in what you buy, and Dr Chris plays tricks on Dr Xand to see how much more activity he can fit into his day.
