Edd Langmead, a 44-year-old father of two from Oldham, has warned others about the dangers of weight loss jabs after a severe gallbladder infection nearly killed him. Langmead began using Mounjaro in May 2025 after being told by his GP that the NHS waiting list for weight loss medication was over 12 months. He lost 5 stone 13 pounds in under a year, dropping from 20 stone 7 pounds to 14 stone 5 pounds.
On March 9, 2025, Langmead experienced pain he thought was trapped wind. Three days later, he was found doubled over in pain and was rushed to hospital by ambulance. Doctors diagnosed gangrenous cholecystitis, a life-threatening condition where gallbladder tissue dies, which they linked to his rapid weight loss. The infection also spread to his stomach and lungs.
Langmead underwent emergency gallbladder removal surgery on March 13. He spent four days in hospital and required a further 10 days of intravenous antibiotics at home. Surgeons told him he was lucky to be alive. Langmead said: 'All I could think of was leaving my kids without a dad.'
He has since stopped using the jabs and urges others to obtain them through their GP for proper monitoring. 'The online companies don't show you those risks,' he said. 'Make sure you go get regular blood tests. It's not worth the risk.'
Lilly, the manufacturer of Mounjaro, stated: 'Patient safety is Lilly’s top priority... The Mounjaro Patient Information Leaflet warns that cholecystitis is an uncommon side effect (may affect up to 1 in 100 people).'
