Weight-loss jabs linked to reduced risk of 42 conditions including dementia

People with diabetes taking medications found in weight-loss jabs have a reduced risk of 42 conditions, research has found, paving the way for such drugs being used to treat a host of health problems.The most comprehensive study of its kind showed that psychotic disorders, infections and dementia were among conditions found to be less likely to occur when using GLP-1RAs, which are found in the medications Saxenda, Wegovy and Mounjaro.The researchers compared health outcomes for people with diabetes who received usual care with those also given drugs such as liraglutide, semaglutide and tirzepatide.While the team revealed the risk of many conditions was lower for the latter group, the risk of other conditions, including arthritic disorders, was increased.And the scientists say that the benefits are not just restricted to people with diabetes, suggesting they could also be found in other people using the jabs, such as those who take them to fight obesity.

“We only studied people with diabetes but there is no biologic or clinical reason to think that the beneficial and risk profiles would be very different in people without diabetes,” said Dr Ziyad Al-Aly, a co-author of the research from Washington University in St Louis.However, Aly said it was unlikely people without obesity would experience a similar range of potential benefits.He added that some of the positive associations might be linked to weight loss, while it was also important to consider the risks.Writing in the journal Nature Medicine, the team report how they analysed records from the US Department of Veterans Affairs databases to explore associations between GLP-1RAs and 175 health outcomes.The data included 215,970 individuals with diabetes who received these drugs in addition to usual care in the form of other blood-sugar lowering medications, as well as 1,203,097 individuals with diabetes who only received usual care.

Participants were tracked for a median of about 3.5 years with the average body mass index above the threshold for obesity.“We wanted, literally, to map the landscape of benefits and risks,” said Aly.The results reveal that, compared with usual care, GLP-1RAs were associated with a lower risk of 42 health outcomes, from clotting disorders to chronic kidney disease.More specifically, the risk was reduced by 13% for opioid-use disorders; 19% for bulimia; 18% for schizophrenia and other psychotic disorders; 10% for suicidal ideation, attempt or intentional self-harm; 12% for Alzheimer’s disease; and 12% for bacterial infections.

However the team found GLP-1RAs were associated with a greater risk of 19 conditions compared with usual care, including abdominal pain, nausea and vomiting, low blood pressure and kidney stones.While some associations were expected, Aly noted others – such as the lower risk of infection – were more puzzling.And while Aly noted weight loss could lead to less arthritis because there was less stress on weight-bearing joints, the new study found that people taking GLP-1RAs had an increased risk of arthritis.“This is likely related to decreased muscle mass and some deconditioning that happens in people who rapidly lose weight,” Aly said, although he noted this required further research.The health associations linked to GLP-1RAs were also compared with those for hundreds of thousands of individuals receiving other types of anti-diabetic medication.

Again, the team found the GLP-1RA drugs were associated with a reduced risk of many conditions, but an increased risk of others.“This type of analysis can teach us about mechanisms of diseases that we have not considered previously – and could open pathways to new treatments for these conditions,” said Aly.It is not the first time GLP-1RAs have been linked to a host of potential health benefits: researchers are already exploring whether they could prove helpful in areas ranging from dementia to cancer.Prof Naveed Sattar of the University of Glasgow, who was not involved in the study, said randomised trials were needed to explore new associations suggested by the study, but noted trials had already proved many of the potential benefits, such as a reduced risk of heart attacks.“As more larger trials report, we will learn more about these classes of medicines, especially those that also give big weight loss, allowing us to better understand their net benefits and safety and potential widening their indications,” he said.

Prisons minister aims to close one women’s jail in England and Wales

A women’s jail in England or Wales should be closed by diverting offenders to alternative forms of punishment and rehabilitation, the prisons minister, James Timpson has said.In an interview with the Guardian, the former head of the shoe repair chain said the government planned to reverse the rise in the number of women being sent to jail, around half of whom are mothers.Instead, hundreds of female offenders could be tagged and sent to addiction and rehabilitation centres, allowing ministers to close at least one of 12 women’s prisons, Lord Timpson said.“We would like to get to a stage where we can close a women’s prison.“There are a number of women that need to be there

Rachel Reeves’s duty is to the people, not the markets | Letters

Your editorial (14 January) rightly critiques Rachel Reeves’s adherence to Treasury orthodoxy. But the persistence of this framework goes deeper than institutional inertia. It reflects a failure to recognise a choice at all – and an inability to imagine and craft better alternatives.Treasury orthodoxy is rooted in the Thatcher-Reagan era. It is not just outdated, but has become invisible to those who wield it

Work on some of Boris Johnson’s ‘40 new hospitals’ will not start until 2039

Work on some of the 40 new hospitals Boris Johnson promised to build by 2030 will not begin until 2039, after a Labour rethink on a pledge it called “a work of fiction” by the Conservatives.The cost of completing the urgently needed new facilities has rocketed from £20bn to close to £50bn after years of limited progress since Johnson first promised them in 2019.The delay to many of the projects has prompted warnings from the bosses of some of the hospitals affected that their decrepit buildings will not survive until the date they are now due to be replaced – as far away as the 2040s in some cases – and will either fall down or face “catastrophic failure” before then.The health secretary, Wes Streeting, told MPs on Monday that construction on 16 of the 40 projects in England would begin between 2025 and 2030. But there would be no spades in the ground at another nine sites until 2030-35 and at a further nine not until 2035-39, he said

Can Labour cut welfare spending and still be seen as a party of social justice?

One of the most important takeaways from last week’s high court ruling declaring the government consultation on reform of incapacity benefits to be unlawful was the clarity with which it highlighted the failure of Conservative ministers to be honest about why they wanted the changes, and who will lose out as a result.The ruling effectively pointed out that the previous administration’s presentation of cuts to incapacity benefit as a positive development for low-income claimants was misleading because it unaccountably neglected to mention 420,000 of them would also be £416 a month out of pocket, and many of them thrust into abject poverty.While the consultation had emphasised the transformative job opportunities that would potentially become available to sick and disabled claimants once freed from the grip of benefit dependency, it failed to explain that the “primary rationale” of the whole exercise was Treasury spending cuts.Labour is to rerun that consultation in the form of a green paper expected in the next few weeks, and there is likely to be intense scrutiny of the clarity – and honesty – with which it presents tough policy choices made even tougher by what some would say are the unnecessarily rigid economic rules it has imposed on public spending.Few object to the need to reform the notoriously poorly designed incapacity benefit system, or to help disabled and chronically ill people get a job if they are able
