A meta-analysis published in Endocrinology, Diabetes & Metabolism in September 2026 puts a number on something patients ask about far more often than they are answered: what happens after you stop. Pooling six studies and 1,776 participants, it estimates weight comes back at 1.04 kg per month, that half of everything lost is back within … Read more
An updated systematic review published in Annals of Internal Medicine on 1 September 2026 pooled 38 randomised trials covering 25,816 adults who had overweight or obesity but not diabetes. It is the cleanest single answer yet to the question most readers arrive with: how much weight does each of these drugs actually take off, above … Read more
A new cohort study adds to a now-consistent finding: people taking semaglutide or tirzepatide are diagnosed with non-scarring hair loss more often than matched non-users. This is not a fringe signal — hair loss is printed on the Wegovy label, among the adverse reactions occurring in at least 2% of treated patients and more often … Read more
A case report published on 26 August describes a man in his mid-30s with long-standing type 1 diabetes who was admitted to hospital with severe vomiting, diarrhoea, high blood sugar, ketones and acute kidney injury, shortly after self-administering a product he had bought online marketed as retatrutide. His partner took the same preparation and also … Read more
Eli Lilly reported on 23 July 2026 that retatrutide, an investigational triple hormone receptor agonist, met its primary endpoint in two further Phase 3 trials. Participants with obesity and type 2 diabetes lost up to an average of 20.8% of body weight over 80 weeks; those with severe obesity and established cardiovascular disease lost up … Read more
The FDA has approved a new indication for Mounjaro (tirzepatide): lowering the risk of major adverse cardiovascular events — cardiovascular death, non-fatal heart attack, or non-fatal stroke — in adults with type 2 diabetes who are at high risk for them. Eli Lilly announced the approval on 28 August 2026. It is the first cardiovascular … Read more
A large propensity-matched cohort study published in Diabetes, Obesity and Metabolism on 27 August 2026 found that people who started a GLP-1 receptor agonist were modestly more likely to be diagnosed with diabetic retinopathy, and more likely to undergo a retinopathy procedure, than matched people who started a DPP-4 inhibitor instead. The same study found … Read more
Trial results describe what happens under close supervision with motivated volunteers. A study published in August in The Lancet Diabetes & Endocrinology asked a harder question: among 45,093 real patients with obesity and type 2 diabetes, how many actually hit a meaningful combined target a year after starting treatment? The answer for semaglutide was 3.0%. … Read more
