10 Indicators of Blocked Arteries You Shouldn’t Ignore
Blocked arteries are often caused by atherosclerosis, a buildup of plaque (cholesterol, fat, and other substances) inside blood vessels. They may develop slowly and sometimes cause no symptoms until blood flow becomes significantly reduced.
Here are 10 warning signs that should not be ignored:
1. Chest pressure or discomfort
- A feeling of tightness, squeezing, heaviness, or burning in the chest—especially during activity—may indicate reduced blood flow to the heart.
2. Shortness of breath
- Feeling unusually breathless during normal activities can occur when the heart is not receiving enough oxygen.
3. Pain spreading to other areas
- Discomfort that travels to the left or right arm, shoulder, neck, jaw, or back can be associated with heart artery problems.
4. Unexplained fatigue
- Extreme tiredness, reduced stamina, or difficulty doing usual activities may sometimes be linked to poor circulation.
5. Leg pain during walking
- Cramping or aching in the calves, thighs, or hips that improves with rest can be a sign of reduced blood flow in the leg arteries.
6. Cold, numb, or tingling feet and legs
- Poor circulation can affect temperature and sensation in the lower limbs.
7. Slow-healing wounds
- Cuts or sores—especially on the feet—may take longer to heal when blood supply is reduced.
8. Dizziness or fainting
- Reduced blood flow or heart-related circulation problems can sometimes contribute to these symptoms.
9. Erectile difficulties
- In some men, circulation problems affecting blood vessels may appear as erectile dysfunction before other cardiovascular symptoms.
10. Stroke warning signs
Sudden symptoms may indicate a blocked artery supplying the brain:
- Face drooping
- Arm weakness or numbness
- Trouble speaking
- Sudden vision problems
- Loss of balance or severe confusion
