Weight-loss jabs linked to multiple deaths as hundreds report problems
The Medicines and Healthcare products Regulatory Agency (MHRA) data reveals that since the licensing of these drugs, there have been hundreds of acute and chronic pancreatitis cases among those taking GLP-1 medicines.
This includes:
181 reported cases of acute and chronic pancreatitis linked to tirzepatide – the active ingredient for Mounjaro. Five people died.
116 reported reactions of this kind linked to liraglutide, one of which was fatal.
113 cases of acute and chronic pancreatitis linked to semaglutide – the active ingredient for Ozempic (licensed to treat type 2 diabetes) and Wegovy. One person died.
101 reported reactions of this kind linked to exenatide, three people died.
52 reported reactions of this sort linked to dulaglutide and 11 reported reactions lixisenatide. No fatalities were linked to either drug.
These incidents are not definitively attributed to the medication, but the person who reported them, suspected a possible link. However, the Yellow Card Biobank project, a collaboration between the MHRA and Genomics England, will investigate whether pancreatitis cases linked to GLP-1 drugs could be influenced by genetic factors.
The MHRA is urging individuals taking GLP-1 medicine who have been hospitalised due to acute pancreatitis to submit a report to its Yellow Card scheme. Upon receipt of a Yellow Card report, the MHRA will reach out to patients to inquire if they would be willing to participate in the study.
Patients are being invited to provide additional details and a saliva sample for examination, which will determine if genetic factors may increase their risk of acute pancreatitis when taking certain medicines. GLP-1 agonists, commonly used to reduce blood sugar levels in people with type 2 diabetes, are also prescribed to aid weight loss for some individuals, reports Wales Online.
Recent estimates suggest that about 1.5 million people in the UK are taking weight loss jabs. Health officials have suggested that they can help to turn the tide on obesity, but have stressed they are not a silver bullet and do come with side effects.
Most side effects linked to the jabs are gastrointestinal including nausea, constipation and diarrhoea. And the medical regulator recently warned that Mounjaro may make the oral contraceptive pill less effective in some patients.
Dr Alison Cave, MHRA's chief safety officer, said: "Evidence shows that almost a third of side effects to medicines could be prevented with the introduction of genetic testing, it is predicted that adverse drug reactions could cost the NHS more than £2.2 billion a year in hospital stays alone.
"Information from the Yellow Card Biobank will help us to better predict those most at risk of adverse reactions – enabling patients across the UK to receive the safest medicine for them, based on their genetic makeup. To help us help you, we're asking anyone who has been hospitalised with acute pancreatitis while taking a GLP-1 medicine to report this to us via our Yellow Card scheme.
"Even if you don't meet the criteria for this phase of the Biobank study, information about your reaction to a medication is always extremely valuable in helping to improve patient safety."
Professor Matt Brown, chief scientific officer of Genomics England, said: "GLP-1 medicines like Ozempic and Wegovy have been making headlines, but like all medicines there can be a risk of serious side effects. We believe there is real potential to minimise these with many adverse reactions having a genetic cause.
"This next step in our partnership with the MHRA will generate data and evidence for safer and more effective treatment through more personalised approaches to prescription, supporting a shift towards an increasingly prevention-focused healthcare system."

Sir Keir Starmer vows to fix ‘broken NHS' by dragging it ‘from bricks to clicks' in a technological revolution
Meanwhile, Wes Streeting revealed the shock amount of Government MPs that are using fat jabs NHS TECH BOOST Sir Keir Starmer vows to fix 'broken NHS' by dragging it 'from bricks to clicks' in a technological revolution SIR Keir Starmer has vowed to fix the 'broken NHS' by dragging it 'from bricks to clicks' in a technological revolution. The Prime Minister and his Health Secretary Wes Streeting said an NHS app and local medical centres will transform healthcare. 3 Sir Keir Starmer has vowed to fix the 'broken NHS' by dragging it through a technological revolution Credit: Getty Launching a ten-year health plan yesterday, they said it was 'change or bust'. Focus will be pulled out of expensive hospitals and into community health clinics, at-home care and online booking and chat systems. Experts hailed their ambitions but warned the changes will take time and money, and that similar plans had failed. Sir Keir said: 'We need to make the NHS fit for the future with technology that is available to us now.' The 168-page plan said the NHS must stop being a 'technological laggard' and 'make the move from bricks to clicks'. Sir Keir added: 'Entire industries have reorganised around apps — retail, transport, finance, weather — why not the NHS? 'It will be like having a doctor in your pocket, providing you with 24-hour advice, seven days a week.' Health Secretary Mr Streeting said: 'People will feel the change over the course of this Parliament and of course this is also a plan for the decade. 'We know the change in our plan is possible because it's already happened. 'We toured the length and breadth of the country and scouted the world for the best examples of reform. 'We will take the best of the NHS to the rest of the NHS.' Keir will ABOLISH NHS England to bring health service 'into heart of Government' 3 Labour launched a ten-year health plan yesterday Wes: Half of our MPs on fat jabs By Sam Blanchard HALF of Government MPs are using fat jabs and boast about it at work, Wes Streeting claimed yesterday. The Health Secretary said injections such as Wegovy and Mounjaro are 'the talk of Commons tea rooms'. He vowed to make them available from the NHS online, in pharmacies or in shopping centres as part of his ten-year health plan. Mr Streeting said: 'Weight-loss jabs are the talk of the House of Commons. Half my colleagues are on them and are judging the rest of us saying, 'You lot should be on them'. 'I'm bringing to weight loss jabs the principle of fairness. They should be available based on need and not the ability to pay.' They cost up to £200 a month, bought at chemists. Boris Johnson and Nadine Dorries admit using them.

Scientists just found a sugar switch that 'protects your brain from Alzheimer's'
The lead author of a new study believes "our brain's hidden sugar code could unlock powerful tools for combating dementia" Brits with a sweet-tooth might actively try to curb temptation when they feel they have been raiding the cupboards or sweetie drawer too much. However, did you know sugar could actually hold a major brain benefit? Scientists have uncovered a surprising sugar-related mechanism inside brain cells that could transform how we fight Alzheimer's and other dementias. In Scotland, an estimated 90,000 people are living with dementia, and approximately 66 per cent of those have Alzheimer's disease, according to Alzheimer's Research UK. Now, a new study from scientists at the Buck Institute for Research on Aging has revealed a surprising player in the battle against Alzheimer's disease and other forms of dementia - brain sugar metabolism. Published in Nature Metabolism, the research uncovers how breaking down glycogen - a stored form of glucose - in neurons may protect the brain from toxic protein build-up and degeneration. Glycogen is typically thought of as a reserve energy source stored in the liver and muscles. While small amounts also exist in the brain, its role in neurons has long been dismissed. "This new study challenges that view, and it does so with striking implications," says Professor Pankaj Kapahi, PhD, senior scientist on the study. "Stored glycogen doesn't just sit there in the brain; it is involved in pathology." The researchers discovered that in both fly and human models of tauopathy (a group of neurodegenerative diseases including Alzheimer's), neurons accumulate excessive glycogen. More importantly, this build-up appears to contribute to disease progression. But tau, the protein that clumps into tangles in Alzheimer's patients, appears to physically bind to glycogen, trapping it and preventing its breakdown. When glycogen can't be broken down, the neurons lose an essential mechanism for managing oxidative stress, a key feature in aging and neurodegeneration. By restoring the activity of an enzyme called glycogen phosphorylase (GlyP), researchers found they could reduce tau-related damage in fruit flies and human stem cell-derived neurons. "By increasing GlyP activity, the brain cells could better detoxify harmful reactive oxygen species, thereby reducing damage and even extending the lifespan of tauopathy model flies," said postdoc Sudipta Bar. Even more promising, the team demonstrated that restricting one's diet naturally enhanced GlyP activity and improved tau-related outcomes in flies. They further mimicked these effects and showed that the benefits of DR might be reproduced through drug-based activation of this sugar-clearing system. "This work could explain why GLP-1 drugs, now widely used for weight loss, show promise against dementia, potentially by mimicking dietary restriction," said Kapahi. "Work in this simple animal allowed us to move into human neurons in a much more targeted way." Kapahi says this study not only highlights glycogen metabolism as an unexpected hero in the brain but also opens up a new direction in the search for treatments against Alzheimer's and related diseases. "As we continue to age as a society, findings like these offer hope that better understanding - and perhaps rebalancing - our brain's hidden sugar code could unlock powerful tools for combating dementia," he added.
