The need for clinical studies assessing whether weight loss improves functional outcome after stroke in diabetes

Type 2 diabetes worsens functional outcome after stroke, severely affecting the rehabilitation processes, with no therapy available for this medical problem.

Weight loss is an effective strategy for managing type 2 diabetes, with some studies also showing that it can reduce cardiovascular and stroke risk in this population. Recent animal studies suggest that weight loss induced by a diet change or pharmacologically (via the activation of the glucagon-like peptide 1 receptor) also improves functional outcome after stroke. Today, however, no clinical study has yet addressed this question. This issue is important to address since type 2 diabetes is one of the strongest risk factors for stroke and the growing prevalence of diabetes is leading to an increasing number of stroke patients with type 2 diabetes who will require effective therapies. Here, we discuss recent findings showing the positive effects of weight loss in type 2 diabetes and its cardiovascular complications, underlining the need to perform new clinical studies specifically focused on understanding the potential therapeutic role of weight loss to improve functional outcomes after stroke.

In summary, this debate underscores a critical clinical gap in current post-stroke care strategies and highlights the potential for weight loss as a novel treatment paradigm to improve functional stroke outcomes in type 2 diabetes. If validated in clinical studies, this approach will significantly improve the quality of life of many stroke patients with type 2 diabetes.
