10 Critical Warning Signs That Your Arteries Are Clogged—and What to Do

Introduction

Clogged arteries, also known as atherosclerosis, occur when plaque (fat, cholesterol, calcium, and other substances) builds up in your blood vessels, restricting blood flow. Left untreated, this condition can lead to heart attack, stroke, or other serious health issues. Recognizing the warning signs early—and taking steps to improve your cardiovascular health—can be life-saving.

Here are 10 critical warning signs that your arteries may be clogged and what you can do about them.

1. Chest Pain or Pressure (Angina)

A classic symptom, chest pain often occurs when blood flow to the heart is restricted. It may feel like heaviness, tightness, or burning.

What to do: If chest pain is frequent or severe, seek medical attention immediately.

2. Shortness of Breath

When arteries are narrowed, your heart struggles to pump enough blood and oxygen, leading to breathlessness even with mild exertion.

What to do: Don’t ignore ongoing shortness of breath. See a healthcare professional for evaluation.

3. Fatigue and Weakness
