Hospital admissions linked to suspected reactions from popular weight-loss jabs have jumped by 60 per cent, with three fatalities now on record.
NHS medics dealt with 133 cases needing emergency care during the first 11 months of 2025 alone, marking a sharp rise from the 83 incidents logged throughout the whole of 2024.
The figures, which The Sun obtained through a Freedom of Information request to the Medicines and Healthcare Regulatory Agency, paint a troubling picture of the slimming injection trend sweeping Britain.
Among those treated for suspected adverse reactions, 106 cases were classed as serious, while 24 fell into the non-serious category. The drugs involved included Ozempic, Wegovy and Mounjaro.

The trend has escalated dramatically over recent years. Back in 2023, doctors recorded just 20 suspected side-effect cases. Go back to 2022, and there were only seven.
On top of the hospital cases, thousands more incidents have been flagged directly to the MHRA through its online reporting system.
What's more, an estimated 1.5 million Britons bought weight-loss injections privately last year, raising serious questions about whether regulation is keeping pace with demand.
Some famous faces have shared their own ordeals with these medications, including model Lottie Moss, 27, who ended up in hospital after suffering seizures while using Ozempic.
Pop star Robbie Williams, 51, has pointed the finger at Mounjaro for causing problems with his eyesight.
Even former Prime Minister Boris Johnson, 61, wasn't spared, experiencing intense nausea and vomiting.

The recognised side effects of these jabs are wide-ranging, causing milder issues like digestive troubles like diarrhoea, feeling sick and being sick.
But things can get more serious, with complications such as pancreatitis, gallstones, and even bone fractures, all documented.
Chief executive of the Independent Pharmacies Association, Leyla Hannbeck, has sounded the alarm about what lies ahead.

She said: "I suspect this problem will only get worse. There has to be better regulation or more people will get ill and there will be more deaths."
How do these drugs work?
Ozempic, Wegovy and Mounjaro are all GLP-1 receptor agonists.
They copy a natural gut hormone that gets released after meals, slowing stomach emptying and making people feel fuller for longer.
The NHS keeps tight controls on who can get these medications, only prescribing them to obese patients with additional conditions like diabetes or high blood pressure.
