What is Atherosclerosis?

Atherosclerosis is a complex and progressive disease that affects the arteries, which are the blood vessels responsible for carrying oxygen-rich blood from the heart to the rest of the body. It is characterized by the buildup of plaque, a combination of cholesterol, fat, calcium, and other substances, on the inner walls of the arteries.

This plaque buildup gradually narrows and hardens the arteries, leading to a condition known as stenosis. As a result, the flow of blood becomes restricted, and the affected organs and tissues may not receive an adequate supply of oxygen and nutrients.

Causes and Risk Factors

Atherosclerosis is primarily caused by a combination of genetic and lifestyle factors. High levels of low-density lipoprotein (LDL) cholesterol, commonly referred to as “bad” cholesterol, can accumulate in the arterial walls and initiate the formation of plaque. Other risk factors include:

• High blood pressure
• Smoking
• Diabetes
• Obesity
• Sedentary lifestyle
• Poor diet
• Family history of cardiovascular disease

Symptoms and Complications

Atherosclerosis often develops silently over many years, and symptoms may not become apparent until a significant blockage occurs. Common symptoms include:

• Chest pain or angina
• Shortness of breath
• Fatigue
• Weakness
• Dizziness
• Numbness or coldness in the extremities

If left untreated, atherosclerosis can lead to serious complications, such as:

• Coronary artery disease
• Heart attack
• Stroke
• Peripheral artery disease
• Kidney disease

Prevention and Treatment

Preventing or managing atherosclerosis involves adopting a heart-healthy lifestyle. This includes:

• Eating a balanced diet low in saturated and trans fats
• Engaging in regular physical activity
• Quitting smoking
• Maintaining a healthy weight
• Controlling blood pressure and cholesterol levels

Treatment options for atherosclerosis depend on the severity of the condition and may include lifestyle modifications, medications to lower cholesterol and blood pressure, and surgical interventions such as angioplasty or bypass surgery.
