Connecting the dots: The overlap between Chronic Venous Insufficiency and Diabetes

As healthcare professionals, we often encounter patients with multiple comorbidities. Two conditions that frequently co-occur are Chronic Venous Insufficiency (CVI) and type 2 diabetes. While these may seem like distinct entities, a closer examination reveals they share more than just a patient population they share risk factors, pathophysiological mechanisms, and even treatment considerations.

Shared risk factors and pathophysiology

CVI and type 2 diabetes are linked by several common risk factors: lack of physical activity, smoking, hypertension, obesity, and ageing. These shared risk factors contribute to the overlapping pathophysiological traits observed in both conditions. For instance, endothelial dysfunction, oxidative stress, and inflammation are key drivers in the development of both CVI and diabetes. These factors increase vascular permeability, reduce lymphatic flow, and ultimately lead to edema and skin changes.

Patients with both conditions are more susceptible to local tissue hypoxia, which can manifest as leg ulcers—a serious complication that underscores the clinical overlap between these diseases.

A vicious cycle: CVI and diabetes complications

Research indicates that type 2 diabetes can exacerbate the severity of CVI, leading to a more aggressive disease course. Conversely, patients with both CVI and diabetes experience higher rates of diabetic microvascular complications than those with only one of these conditions. The prevalence of deep venous incompetence is also significantly higher among diabetic patients, suggesting that diabetes induces hemodynamic and morphological changes in the veins. This sets up a vicious cycle where each condition amplifies the other's impact, creating a challenging scenario for management.

Implications for practice: Overlapping treatment strategies

Understanding the interplay between CVI and diabetes opens the door to potential overlapping treatment strategies. It suggests the need for a more holistic approach to patient management, where screening for both conditions becomes a routine part of care. For example, in a diabetic outpatient clinic, assessing for CVI could lead to earlier detection and management, potentially altering the disease trajectory for both conditions.

Looking ahead: A call to action

Recognizing the interconnected nature of CVI and diabetes is just the beginning. As clinicians, our next step is to refine our diagnostic processes and treatment protocols to better manage these coexisting conditions. By doing so, we can help break the cycle of worsening symptoms and improve overall patient outcomes.

As we continue to explore these connections, the opportunity to innovate in patient care is significant. Let’s stay vigilant, stay curious, and most importantly, stay committed to improving the lives of our patients.
