Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study compared the effects of pharmacological treatment, bariatric surgery, and a very-low-calorie diet on insulin resistance in patients with type 2 diabetes and hypertension, finding significant improvements in insulin resistance and weight loss with surgery and diet.
The findings highlight the potential of bariatric surgery and very-low-calorie diets as effective interventions for managing insulin resistance and weight in patients with type 2 diabetes and hypertension. This could inform treatment strategies and improve patient outcomes, emphasizing the need for tailored approaches in managing these chronic conditions.
The study's cohort design may limit causal inferences. Sample size and demographic diversity were not specified. Long-term effects of interventions were not assessed.

Bariatric surgery reduced insulin resistance by 88.7% (p < 0.0001).
Very-low-calorie diet led to a significant weight loss of 17.4% (p < 0.0001).
Pharmacological treatment showed an insignificant weight loss of 6.5% (p = 0.06).
