GPs: Behind Closed Doors (2014)

Season 3: Episode 20

Cameras return to Balham Park Surgery, with the GPs trying to help patients who pose a danger to themselves. Long-term patient Allan, who has a number of long-standing health conditions, arrives in Dr Sian Morris's consultation room, claiming that his weight loss is due to the stress of recently moving house. However, the doctor suspects a more sinister cause - crack cocaine - and leaves Allan in no doubt as to the risks of continuing with such a dangerous habit.
