10 Signs of Blocked Arteries You Shouldn’t Ignore
Blocked arteries (often caused by atherosclerosis, a buildup of plaque inside blood vessels) can reduce blood flow to the heart, brain, or other parts of the body. Symptoms may be subtle, so it’s important to pay attention to warning signs.
1. Chest discomfort or pressure
A feeling of squeezing, heaviness, tightness, or burning in the chest—especially during activity—can be a warning sign of reduced blood flow to the heart.
2. Shortness of breath
Difficulty breathing during normal activities or unexplained breathlessness may occur when the heart is not receiving enough oxygen.
3. Pain spreading to the arm, shoulder, neck, jaw, or back
Heart-related discomfort does not always stay in the chest and may appear in other areas.
4. Unusual fatigue
Feeling extremely tired without a clear reason, especially with activity, can sometimes be linked to heart problems.
5. Dizziness or lightheadedness
Reduced blood flow to the brain or heart issues can sometimes cause these symptoms.
6. Leg pain while walking
Pain, cramping, or weakness in the legs during walking that improves with rest may be a sign of peripheral artery disease.
7. Cold or numb feet and hands
Poor circulation can cause changes in temperature, sensation, or skin color in the extremities.
8. Slow-healing wounds
Cuts or sores on the feet and legs that take a long time to heal may indicate reduced circulation.
9. Irregular heartbeat or palpitations
A racing, fluttering, or irregular heartbeat should be evaluated, especially if it occurs with other symptoms.
10. Sudden neurological symptoms
Sudden weakness, numbness on one side of the body, trouble speaking, confusion, or vision changes may signal a stroke and require emergency care.
