This week: how quickly weight returns after stopping semaglutide or tirzepatide, why a borderline normal haemoglobin may deserve a closer look, twelve month results for automated insulin delivery in type 1 diabetes, why the testosterone dose matters for heart rhythm, and what two million people can and cannot tell us about drinks and mood.

In this episode.

Weight regain after stopping a GLP-1, from a pooled analysis of six randomised trials in Endocrinology, Diabetes and Metabolism.

Borderline low haemoglobin and mortality, from half a million adults in the UK Biobank, published in Annals of Internal Medicine.

Automated insulin delivery at twelve months in adults with type 1 diabetes.

Testosterone and atrial fibrillation, and why the target level matters, from the Journal of the Endocrine Society.

Drinks, depression and anxiety, from fifty-nine studies covering more than two million people.

Every story carries its caveat in the episode. Correlation is not causation, and preliminary findings are flagged as preliminary.
