A GP who taught dozens of his own patients with type 1 diabetes to build unapproved medical devices to manage their condition says a new randomised control trial has vindicated his work.

Six years ago Dr Kenny Clark, who has type 1 diabetes himself, discovered ‘looping’ — following instructions on social media to connect commercially available insulin pumps to continuous glucose monitoring systems in a feedback loop.

It means his insulin dosing is now adjusted automatically based on glucose readings, although he can still make manual adjustments on his homemade device.

Since 2018, Dr Clark says he has taught around 70 patients about the same DIY technology.
