A diabetic teenager from Hampshire has become the first in the world to be fitted with an implant designed to improve the resistance to insulin and aid weight loss.
Victoria Parr, 17, from Lymington, had the small plastic sleeve placed in her upper intestine.
The non-surgical device, called EndoBarrier, helps patients to lose weight by ensuring food bypasses a part of the upper intestine, which means there is less time for it to be absorbed and digested.
Doctors said this could reduce the need for medication in people with type 2 diabetes and help tackle the growing obesity crisis.
The EndoBarrier was fitted by a team of doctors at Southampton General Hospital led by Dr Nikki Davis, a consultant paediatric endocrinologist, and James Byrne, a consultant surgeon.
Dr Davis said: “This is potentially a major addition to the treatments currently available for severe type 2 diabetes and obesity in teenagers, and could help to address the progression of the condition and the early development of complications in an increasing number of cases among children and adolescents.”
