The Aporia · Fat jabs like Ozempic and Mounjaro more effective than diabetes drug metformin at preventing the disease - and patients have fewer side effects, major analysis finds

A study suggests that GLP-1 receptor agonist drugs like Ozempic and Mounjaro are more effective than metformin at preventing type 2 diabetes, reducing the risk by 31% for those with prediabetes. The analysis of over 250,000 adults found these injections also lowered the risk of death from any cause by 41%, heart attacks by 15%, and strokes by 20%. Researchers at the Mayo Clinic believe these drugs could be used earlier to prevent diabetes progression due to their effectiveness in reversing prediabetes.

Story summary

A major analysis suggests that fat jabs like Ozempic and Mounjaro may be more effective at preventing type 2 diabetes compared to metformin, currently the gold standard treatment. The Mayo Clinic in Arizona's research found that patients on GLP-1 injections had a 31% lower risk of developing type 2 diabetes and were also less likely to suffer heart attacks, strokes, or heart failure. Additionally, these patients had a 41% lower risk of dying from any cause compared to those taking metformin. This could shift the use of GLP-1 medications to earlier stages for certain patients, potentially reversing prediabetes progression and reducing long-term health risks. The study highlights that one in 12 Britons are affected by prediabetes.

Why this leaning score

This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
