Woman Hospitalized for 10 Days After Taking Weight Loss Drug Mounjaro

In late April 2025, Clare Meadowcroft, a 50-year-old publican, was hospitalized for 10 days with acute pancreatitis after taking the weight loss drug Mounjaro for just 4 weeks. Meadowcroft, who had struggled with her weight for years, turned to Mounjaro after hearing positive reviews from friends. However, the drug caused her to develop a severe and potentially life-threatening case of pancreatitis.

Doctors warned Meadowcroft to stop taking Mounjaro immediately, as the condition could be fatal. She also underwent major surgery to remove her gallbladder as a precaution, despite the doctors not believing the gallstones had caused the pancreatitis. Meadowcroft, who had never had any major health issues before, was shocked by the ordeal, saying "All this to lose some weight?"

In the months since, the Medicines and Healthcare Regulatory Agency (MHRA) has launched a study to investigate the link between GLP-1 weight loss drugs like Mounjaro and acute and chronic pancreatitis. Meadowcroft is now at peace with her weight and urges others to be cautious when considering these medications, advising them to go through their GP to ensure proper medical supervision.
