Clogged arteries, also known as atherosclerosis, happen when fatty deposits build up inside the blood vessels. This condition can reduce blood flow, strain the heart, and increase the risk of heart attack or stroke. The scary part? You may not notice the warning signs until it’s too late.

Here are 8 silent signs your arteries might be clogged—and what you can do to protect your heart.
1. Frequent Fatigue
If you constantly feel tired even after resting, it could mean your heart isn’t pumping enough oxygen-rich blood through narrowed arteries.

2. Shortness of Breath
Clogged arteries limit oxygen delivery, making even simple activities—like walking up stairs—feel exhausting.

3. Chest Discomfort or Pressure
Not always a sharp pain—sometimes it feels like tightness, heaviness, or burning. This may be an early sign of restricted blood flow.

4. Numbness or Weakness in Limb

Poor circulation can cause tingling, numbness, or weakness in your arms and legs, especially during activity.
