Can medicines that lower appetite help prevent type 2 diabetes?

These medicines were linked to a 31% lower risk of type 2 diabetes than Metformin in adults with prediabetes and obesity. The study compared GLP-1 Medications, which lower appetite and steady blood sugar, with Metformin, a common blood sugar medicine. Researchers reviewed health records for 256,492 adults with prediabetes and obesity. Prediabetes means blood sugar is high, but below the diabetes range. Their average age was 52, and 76% were women. Records came from 104 institutions and covered 2010 through 2023. People in the study were followed for roughly three years. Most earlier research had focused on people already living with type 2 diabetes. Those taking GLP-1 Medications had 1.5 times the chance of returning to normal blood sugar. They also had a 41% lower risk of death from any cause. Heart findings pointed in the same direction: 15% fewer heart attacks and 20% fewer strokes. There were also 25% fewer cases of heart failure. These are links, not proof that the medicines caused the differences. Researchers reviewed existing records rather than assigning medicines by chance. The 31% figure compares the two groups; it is not everyone's personal risk reduction. The excerpt does not give the actual number who developed diabetes. For BioSocial members, this offers a reason to compare bloodwork over time. Tracking Fasting Blood Glucose alongside medicine start dates can make community discussions more useful. Sharing starting numbers and time between tests adds context that a single result cannot. What changes have you seen in your blood sugar numbers since starting either medicine?
