The Hidden Connection Between Diabetes and Peripheral Artery Disease (PAD)
When most people think about diabetes, the first thing that comes to mind is “high blood sugar.” And while that’s true, the impact of diabetes goes much deeper than sugar levels alone. Diabetes affects the entire body—your heart, kidneys, eyes, nerves, and especially your circulation. One of the most serious complications many people don’t know about is Peripheral Artery Disease (PAD). PAD is a condition where the arteries that carry blood to your legs and feet become narrowed or blocked. For someone with diabetes, the risk of developing PAD is much higher—and when the two conditions combine, they can lead to life-changing consequences if not addressed early. Let’s break it down in clear, simple language so you can understand what’s happening in the body, what signs to look out for, and what steps you can take to protect yourself or your loved ones. What Exactly Is PAD? Your arteries are like highways for your blood. They carry oxygen and nutrients to every part of your body. Over time, factors like high cholesterol, smoking, high blood pressure, or diabetes can cause plaque (a sticky mix of fat and calcium) to build up inside the artery walls. When this happens in the arteries leading to your legs and feet, blood has a harder time getting through. That’s PAD. Think of it like a garden hose that’s clogged with dirt. The water (blood) still tries to flow, but the pressure drops, and not enough gets to the flowers (your muscles, skin, and tissues). Without good circulation, your body struggles to repair itself. How Diabetes Makes PAD Worse For people living with diabetes, the risk of PAD is much higher for several reasons: 1. High blood sugar damages blood vessels. Over time, sugar acts like sandpaper inside your arteries, making the walls rough and sticky. This speeds up plaque buildup. 2. Nerve damage hides the warning signs. Diabetes often causes nerve damage (neuropathy), which means you may not feel pain from PAD as strongly. This makes it easier to miss early warning signs. 3. Poor healing increases complications. Cuts, scrapes, or blisters on the feet may heal very slowly, or not at all, because blood flow is limited.
