ROLE OF CHOLESTEROL IN ATHEROSCLEROSIS:
ATHEROSCLEROSIS:
Atherosclerosis is a medical condition in which plaque (fatty deposition) accumulates in the arteries. These deposits are composed of cholesterol, fatty compounds, cellular waste materials, calcium, and fibrin (a blood clotting material).
GOOD AND BAD CHOLESTEROL:
Controlling cholesterol levels is critical for lowering the risk of atherosclerosis and heart disease.
BAD CHOLESTEROL:
High levels of LDL cholesterol, also known as “bad” cholesterol, are linked to a raised risk of atherosclerosis.
GOOD CHOLESTEROL:
High levels of (HDL) high-density lipoprotein cholesterol, known as “good” cholesterol, on the other hand, are helpful because they assist in eliminating excess cholesterol from the arteries.
FORMATION OF ATHEROSCLEROSIS:
Atherosclerosis is a key cause of heart disease, including coronary artery disease and heart attacks. Here’s how cholesterol comes into play.
1. Plaque Formation:
Cholesterol, specifically low-density lipoprotein (LDL) cholesterol, is a form of fat that can build up in the lining of arteries. When LDL cholesterol levels are high in the blood, it might enter the artery walls and change, increasing its likelihood of retention.
2. Inflammatory Response:
LDL cholesterol in the artery walls causes an inflammatory response. White blood cells move to the site of the inflammatory site, resulting in the production of foam cells. These foam cells bind to cholesterol and other chemicals in the arteries, producing fatty deposits or plaque.
3. Plaque Buildup and Artery Narrowing:
Plaque accumulates over time, narrowing the artery walls and limiting blood flow to the heart. This can result in coronary artery disease, also known as CAD or atherosclerotic heart disease.
4. Rupture and Blood Clot Formation:
The plaque might become unstable and rupture in some circumstances. When this happens, the body reacts by creating a blood clot at the rupture site. If the blood clot grows large
enough to completely block the already restricted artery, it can cause a heart attack.
LIFESTYLE CHANGES THAT CONTROL CHOLESTEROL LEVELS:
Lifestyle changes such as eating a nutritious diet, exercising regularly, maintaining a healthy weight, and not smoking can help regulate cholesterol levels and lower the risk of atherosclerosis and heart
disease. When lifestyle changes alone are insufficient to manage cholesterol levels, medication may be suggested. It is critical to seek personalized advice and direction from a healthcare expert.
Lifestyle adjustments play an essential role in lowering cholesterol and improving overall cardiovascular health. Here’s how each of the following lifestyle habits can help with cholesterol management:
NUTRITIOUS DIET:
A healthy, balanced diet can help lower low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol. Limit your consumption of saturated and trans fats, which are present in fried and processed meals and can boost LDL cholesterol. Consume more unsaturated fats, such as those found in olive oil, avocados, and almonds. In addition, meals high in soluble fiber, such as fruits, vegetables, lentils, and whole grains, can help decrease LDL cholesterol.
EXERCISE ON REGULAR BASIS:
Physical activity has many advantages for cholesterol management. Regular cardiovascular exercises, such as brisk walking, jogging, swimming, or cycling, might raise HDL cholesterol, sometimes known as “good” cholesterol. HDL cholesterol aids in the removal of LDL cholesterol from the bloodstream, lowering the risk of artery plaque formation.
Aim for 150 minutes of aerobic activity or 75 minutes of vigorous exercise every week.
MAINTAINING A HEALTHY WEIGHT:
Excess body weight, particularly belly fat, is linked to higher LDL cholesterol and lower HDL cholesterol. You can acquire and maintain a healthy weight by eating a good diet and exercising regularly, to decrease your LDL and maintain your HDL.
SMOKING:
Smoking harms blood arteries, lowers HDL cholesterol levels, accelerates the oxidation of LDL cholesterol, making it more dangerous. Quitting smoking can raise HDL cholesterol levels and lower your risk of heart disease.
CONCLUSION:
It is crucial to note that lifestyle modifications may take some time to have an impact on cholesterol levels. Furthermore, some people may require medication in addition to lifestyle changes to adequately manage their cholesterol. As a result, seek personalized advice and help on managing your cholesterol levels from your healthcare professional.
