Kidney failure has meant that midwife Sascha has to endure intensive dialysis at hospital just to stay alive. This intense dialysis for hours on end, five days a week, places her body under immense stress with the constant threat of life-risking blood clots. If this continues, Sascha, a mother to four children, has a life expectancy of just a few years. However, Sascha could do self-dialysis daily from her home, and the increase in frequency and the decrease in intensity would mean her life expectancy and lifestyle would improve dramatically. So that is where DIY SOS and the generous volunteers and trades of Billy's home turf, Welwyn Garden City, step up to help one of their own. In an emotionally charged episode, Sascha's family home is completely renovated and extended to include a dedicated home-dialysis room for Sascha, which offers her a lifeline and extra years with her loving family.
