What are the signs of plaque buildup?

Recognizing the Warning Signs of Plaque Buildup

Plaque buildup in the arteries, also known as atherosclerosis, doesn’t always announce itself loudly—but when it does, the signs can be serious. It’s often silent until it starts restricting blood flow, and by then, the consequences may already be underway.

When plaque clogs the arteries supplying blood to your heart, you might feel chest pain or pressure—commonly referred to as angina. This discomfort can spread to your shoulders, arms, neck, or jaw, especially during physical activity or stress. It’s your body’s way of signaling that your heart isn’t getting enough oxygen.

But the danger isn’t limited to the heart. If plaque builds up in the arteries leading to your brain, the warning signs can come on suddenly. You might experience numbness or weakness—especially on one side of the body—difficulty speaking, slurred speech, or even sudden vision loss in one eye. A drooping face, confusion, or dizziness can also be red flags. These symptoms could signal a transient ischemic attack (TIA) or even a full-blown stroke, both linked to blocked arteries.

What many don’t realize is that these signs often develop gradually. Early detection is key. High cholesterol, high blood pressure, smoking, and a sedentary lifestyle all feed into plaque formation over time. The good news? Lifestyle changes like eating better, staying active, and managing stress can slow or even reverse the process.

Don’t wait for a crisis. If you notice any of these symptoms—even if they come and go—take them seriously. Early medical attention can make a crucial difference. Your arteries may not scream for help, but they do send signals. Learning to recognize them could save your life.
