Stockholm, Sweden – New findings published in The Journal of Clinical Inquiry on June 9, 2025, reveal a critical link between vascular health within pancreatic islets and glucose intolerance in obese individuals. The study, led by professor Per-Olof Berggren at the Karolinska Institute, demonstrates that vascular dysfunction in these islets can become permanent if left uncorrected, significantly impacting glucose regulation.
The Vascular-Glucose Intolerance Connection
The research highlights that obesity can induce endothelial cell desensitization to VEGF-A, a crucial factor for maintaining healthy blood vessels. This desensitization leads to impaired islet vessel function, contributing to glucose intolerance. Understanding this vascular pathology opens potential new therapeutic avenues for preserving vascular health in metabolic diseases.
Did You Know? The pancreas contains specialized regions called islets of langerhans, which are responsible for producing insulin, a hormone that regulates blood sugar levels.
Study Details and Funding
The study, titled “Diet-induced obesity promotes endothelial cell desensitization to VEGF-A and permanent islet vessel dysfunction in mice,” was conducted by Yan Xiong, Andrea Dicker, Motshi, and Erwin Ilegems, along with Per-Olof Berggren. the research was supported by grants from several organizations, including the Karolinska Institute, the Swedish Research Council, the Novo Nordic foundation, and the Knut and Alice Wallenberg Foundation.
Implications for diabetes Prevention
Professor Berggren emphasizes that addressing vascular service defects in the pancreatic islets is crucial for preventing the progression of glucose intolerance in obese individuals. Early detection and intervention could potentially prevent permanent damage and reduce the risk of developing type 2 diabetes. Lifestyle modifications, such as diet and exercise, are also important for managing blood sugar and improving vascular health [[2]].
Pro Tip: regular physical activity can improve blood sugar control and overall vascular health. Aim for at least 150 minutes of moderate-intensity exercise per week.
Global Impact of Diabetes
Diabetes mellitus affects approximately 100 million people worldwide, with type 2 diabetes accounting for 90% to 95% of cases [[3]]. The incidence of type 2 diabetes is expected to rise due to lifestyle factors contributing to obesity. Understanding the vascular complications associated with diabetes is essential for developing effective prevention and treatment strategies.

Evergreen Insights: Understanding Glucose Intolerance and Vascular Health
Glucose intolerance, a precursor to type 2 diabetes, is characterized by elevated blood sugar levels after eating. This condition often arises from insulin resistance, where the body’s cells do not respond effectively to insulin. Vascular health plays a crucial role in maintaining proper glucose metabolism. healthy blood vessels ensure efficient delivery of insulin and nutrients to the pancreas and other organs involved in glucose regulation. Impaired vascular function can disrupt these processes, leading to or exacerbating glucose intolerance. Studies have shown that lifestyle interventions, such as diet and exercise, can improve both vascular health and glucose control, highlighting the importance of a holistic approach to managing metabolic health [[2]].
Frequently Asked Questions About Glucose Intolerance and Vascular Health
- What is the link between obesity and glucose intolerance?
- Research indicates that vascular dysfunction within pancreatic islets, frequently enough associated with obesity, significantly contributes to glucose intolerance. This dysfunction can impair insulin secretion and glucose regulation.
- Why is vascular health important in metabolic diseases?
- Vascular health is crucial because blood vessels supply nutrients and oxygen to organs like the pancreas. Impaired vascular function can disrupt the normal operation of these organs, exacerbating metabolic diseases such as diabetes.
- can lifestyle changes improve vascular health?
- Yes, lifestyle modifications such as a balanced diet, regular exercise, and stress reduction techniques can significantly improve vascular health and blood sugar control [[2]].
- What are the potential long-term consequences of impaired glucose tolerance (IGT)?
- Impaired glucose tolerance can increase the risk of developing type 2 diabetes, cardiovascular disease, and even long-term mortality. Early intervention and management are crucial to mitigate these risks [[1]].
- How does diabetes affect vascular disease?
- Diabetes mellitus, particularly type 2, significantly increases the risk of vascular disease. High blood sugar levels can damage blood vessels, leading to complications such as heart disease, stroke, and peripheral artery disease [[3]].
- What new therapeutic possibilities are emerging from vascular pathology research?
- Understanding vascular pathology in pancreatic islets opens avenues for developing targeted therapies aimed at preserving vascular health in individuals with metabolic diseases. These therapies could potentially prevent or reverse glucose intolerance.
