Blocked arteries:

Definition: When arteries become obstructed by plaque buildup, it hinders blood flow, potentially leading to severe health issues like strokes and heart attacks.

Plaque composition: Primarily composed of cholesterol, calcium, and other substances.

Causes:

Elevated cholesterol levels: Plaque, rich in cholesterol, narrows arteries, impeding blood flow.
High blood pressure: Damages artery walls, contributing to narrowing and blockage.
Smoking: Harms artery linings, escalating the risk of plaque accumulation.
Obesity, diabetes, and sedentary lifestyles: Increase susceptibility to arterial blockages.
Certain medications and conditions: Steroids, diabetes medications, chemotherapy, and family medical history play a role.
Warning signs:

Chest discomfort: Pressure or tightness, often accompanied by breathlessness, nausea, or fatigue.
Fatigue: Inadequate supply of oxygen-rich blood to the heart.
Swelling: In legs, feet, or ankles due to poor circulation.
Cold extremities: Resulting from reduced oxygen-rich blood flow.
Breathlessness: Due to insufficient blood and oxygen reaching the heart.
Irregular heartbeat: Palpitations caused by inadequate oxygen supply.
Dizziness or vertigo: Indicates insufficient oxygen-rich blood reaching the brain.
Prevention:

Management of health conditions: Monitoring and controlling high blood pressure and diabetes.
Medications and surgical interventions: Sometimes necessary for treatment.
Conclusion:

Prevention and early detection play crucial roles in managing blocked arteries. Adopting a healthy lifestyle, monitoring existing health conditions, and promptly addressing warning signs reduce the risk of complications. Regular medical check-ups and proactive cardiovascular health measures are fundamental for preventive care.
