Blocked arteries can cause pain that radiates to:
- The neck
- The jaw
- The shoulder
- The left arm
- Sometimes both arms
Many people never connect these symptoms to heart disease.
In some cases, jaw pain may be the only warning sign before a cardiac event.
5. Dizziness or Lightheadedness
The brain depends on a constant supply of oxygen-rich blood.
If circulation becomes compromised, you may experience:
- Dizziness
- Feeling faint
- Loss of balance
- Sudden weakness
These symptoms can occur for many reasons, but they should never be ignored—especially if they appear suddenly.
6. Leg Pain While Walking
Peripheral artery disease (PAD) occurs when plaque builds up in arteries supplying the legs.
One hallmark symptom is called claudication.
This refers to:
- Leg cramps
- Calf pain
- Thigh discomfort
- Pain that appears during walking and improves with rest
The American Heart Association estimates that millions of adults suffer from PAD, many without realizing it.
7. Cold Feet or Cold Hands
Poor circulation can reduce blood flow to the extremities.
You may notice:
- Cold feet
- Cold hands
- Slow-healing wounds
- Changes in skin color
While these symptoms can have multiple causes, reduced circulation should always be considered.
8. Erectile Dysfunction
Many people are surprised to learn that erectile dysfunction can sometimes be an early warning sign of cardiovascular disease.
The arteries supplying the reproductive organs are much smaller than coronary arteries.
Because of this, circulation problems may become noticeable there years before symptoms appear in the heart.
Several studies have found a strong association between erectile dysfunction and future cardiovascular events.
9. Temporary Vision Problems
When arteries supplying the brain or eyes become narrowed, some individuals experience:
- Blurred vision
- Partial vision loss
- Temporary blindness in one eye
These symptoms may represent a transient ischemic attack (TIA), sometimes called a “mini-stroke.”
Immediate medical evaluation is essential.
10. Sudden Weakness or Numbness
A blocked artery affecting blood flow to the brain can trigger symptoms such as:
- Facial drooping
- Arm weakness
- Numbness
- Difficulty speaking
- Confusion
These can be signs of a stroke.
Every minute matters.
Emergency medical care should be sought immediately.
What Causes Arteries to Become Clogged?
Several factors increase the risk of atherosclerosis:
- High LDL cholesterol
- High blood pressure
- Diabetes
- Smoking
- Obesity
- Physical inactivity
- Chronic inflammation
- Family history
- Aging
After age 65, the risk rises significantly.
What Do Studies Show?
Large studies such as the Framingham Heart Study have followed participants for decades and identified several major risk factors that dramatically increase the likelihood of cardiovascular disease.
Research consistently shows that controlling blood pressure, reducing cholesterol, quitting smoking, exercising regularly, and maintaining a healthy weight can significantly lower risk.
According to the Centers for Disease Control and Prevention (CDC), many heart attacks and strokes are preventable through lifestyle changes and proper medical management.
How Doctors Detect Clogged Arteries
Depending on symptoms and risk factors, physicians may recommend:
- Cholesterol testing
- Blood pressure monitoring
- Stress tests
- Coronary calcium scans
- CT angiography
- Ultrasound examinations
- Cardiac catheterization
Early detection often allows treatment before a major event occurs.
The Bottom Line
Clogged arteries rarely happen overnight.
They usually develop slowly over many years.
That’s why recognizing warning signs matters.
Chest discomfort, shortness of breath, unexplained fatigue, leg pain, dizziness, or sudden weakness should never be dismissed as “just getting older.”
Your body often sends signals before a serious problem occurs.
Paying attention to those signals could make all the difference.
If you experience concerning symptoms, consult a healthcare professional promptly.
Sometimes the most dangerous conditions are the ones you cannot see.
