Diabetes and heart disease are closely linked conditions that often develop together over time. High blood sugar levels can gradually damage blood vessels, increasing inflammation and contributing to plaque buildup in the arteries. This process, known as atherosclerosis, reduces blood flow and places extra strain on the heart.

As circulation becomes restricted, the risk of serious complications such as heart attack and stroke increases. Because these changes develop slowly, early warning signs are often subtle and easy to overlook until the condition has progressed.

One of the earliest areas where problems may appear is the feet. Since they are farthest from the heart, they are especially sensitive to reduced circulation. Symptoms like cold feet, swelling, discoloration, or pain while walking can signal underlying vascular issues.

In people with diabetes, nerve damage known as neuropathy can further complicate the situation by reducing sensation. This makes it harder to notice injuries, while slower healing due to poor blood flow increases the risk of infection or worsening wounds.
