Thousands to get 'King Kong' fat jab free on NHS if BMI hits certain threshold

People will be able to get the 'King Kong' of fat jabs on the NHS, it has been revealed. Mounjaro has already been rolled out to people with type 2 diabetes but will soon be given to those with severe obesity too and could help patients lose 24 per cent of the body weight.

London GP and founder of wellgoodwellbeing.com, Dr Zoe Watson, said: “Your body naturally produces an appetite regulating hormone called glucagon-like peptide-1. These jabs work by regulating your appetite, which can lead to eating fewer calories and losing weight.”

The medicine, also called tirzepatide, works in a similar way to celebrity-endorsed Ozempic and Wegovy, will be once-weekly for patients with a body mass index (BMI) of 35 or above. Sir Stephen O'Rahilly, of the Medical Research Council Metabolic Diseases Unit at the University of Cambridge, said drugs like Mounjaro "will become a central plank of how we help people living with obesity to live longer and healthier lives" in a fight against obesity.

He added: "Given the very positive recent results of large, randomised control trials with this drug and its beneficial effects on a range of outcomes, this decision is not surprising. We are clearly in a new era of obesity management where, for the first time, we can have access to medicines which are effective and, though not without some side-effects, largely safe."

Prof Sir Stephen added: "This class of injectable drug is currently expensive, providing particular challenges to a taxpayer-funded health system like the NHS." The statement from the NHS chief went on, saying: "In the longer term, these drugs significantly reduce the risks of developing distressing and expensive complications such as type 2 diabetes, heart attacks and kidney failure but their cost provides an immediate financial challenge at a time when NHS budgets are tight."
