A GP has "prescribed" an 11-year-old boy a two-week ban from computer games such as Fortnite and Minecraft.
Dr Amir Khan, from Leeds, said he issued the advice as he was concerned about the impact gaming was having on the boy's life.
The GP, who stars in the Channel 5 show GPs Behind Closed Doors, shared the prescription on Twitter.
Cam Adair, founder of Game Quitters, said the tweet highlighted the seriousness of gaming addiction.
Dr Khan's tweet came as it was revealed the UK gaming market is now worth a record £5.7bn, while it is estimated there are 32.4 million gamers in the country.
His message has been retweeted more than 350 times and liked by more than 3,000 people, with many commenting that they would like a similar prescription for their child.
The best prescription I gave today was to an 11yr old lad— Dr Amir Khan GP (@DrAmirKhanGP) March 28, 2019

Addictive computer games impacting his life
I even wrote it on a prescription pad and signed it! Good luck to the pharmacist who gets that!😂#ThursdayThoughts
Los Angeles-based Mr Adair set up Game Quitters after battling an addiction to gaming that saw him playing up to 16 hours a day.
He said gaming addiction "can be devastating" and that while Dr Khan's tweet may be "light-hearted", advice to take a break was invaluable.
"I've no doubt that it will have a positive effect, even if it just helps him start to discover other activities in his free time," he said.
Mr Adair added: "People are gaming at such a young age, and gaming is so effective at fulfilling people in so many ways, that they don't really know what else to do with their time.
"By taking a break whether its three days, two weeks or 90 days it gives them an opportunity to create a contrast in their life between life with gaming and life without it. It helps people mitigate against gaming and make it not the only thing they know."
The Royal College of Paediatrics and Child Health (RCPCH) recommends that families should negotiate screen time limits based on need, use and impact on physical activity and suggest that screens are avoided for an hour before the planned bedtime.
However, they say the "evidence base for a direct 'toxic' effect of screen time is contested, and the evidence of harm is often overstated".
Dr Max Davie, officer for health improvement for the RCPCH, said: "Computer games are a vibrant and important aspect of young people's culture.
"However, given they are a sedentary activity, they must be balanced alongside more active pursuits, and used mindfully, making sure that any snacking is carefully controlled."
