Diabetes and heart disease are intricately connected medical conditions, forming a complex interplay that affects multiple systems in the body, from the heart and blood vessels to the extremities. Adults with diabetes face a significantly higher risk of developing cardiovascular disease than those without the condition, a fact well-documented by the American Heart Association (AHA). The American Diabetes Association (ADA) reinforces this concern, noting that cardiovascular complications are the leading cause of death among individuals living with diabetes. This relationship is not coincidental; chronic hyperglycemia, or elevated blood glucose over prolonged periods, contributes to both microvascular and macrovascular damage.

Microvascular complications affect the smallest blood vessels, leading to neuropathy and kidney disease, while macrovascular issues target larger arteries, resulting in coronary artery disease, peripheral artery disease (PAD), and an elevated risk of stroke. Together, these conditions accelerate atherosclerosis, the progressive buildup of plaque in the arteries, which stiffens blood vessels and reduces blood flow, particularly to the lower extremities. The feet, being the most distal parts of the body, become early and visible indicators of underlying vascular issues.
