Cholesterol is a liquid molecule found in the bloodstream. Your body requires cholesterol to form healthy cells, but high cholesterol levels can raise your risk of heart disease. High cholesterol might cause fatty deposits in your blood vessels. These deposits eventually accumulate, obstructing the flow of blood through your arteries. Sometimes, such deposits break unexpectedly and form a clot, resulting in a heart attack or stroke. High cholesterol can be inherited, but it is frequently the result of poor lifestyle choices, making it both avoidable and treatable. High cholesterol can be reduced with a good diet, frequent exercise, and, in some cases, medication.

Symptoms

High cholesterol usually does not cause apparent symptoms. However, if not treated, it might cause major health problems. Here are the main points about its effects:

• No Direct Symptoms: Most persons with high cholesterol do not have any immediate symptoms.

• Fatty Deposits: High cholesterol levels can develop fatty deposits (plaque) in the arteries, resulting in chest pain or angina.

• Heart Disease: Plaque buildup can lead to coronary artery disease, which can produce symptoms such as shortness of breath, exhaustion, and irregular heartbeats.

• Stroke Risk: A blockage in the arteries leading to the brain can result in stroke symptoms such as sudden numbness or weakness in the face, arms, or legs.

• Peripheral Artery Disease: High cholesterol can cause impaired circulation in the legs, resulting in soreness or cramps when walking.

• Xanthomas: Xanthomas are yellowish fatty deposits that grow under the skin, notably around the eyes, and indicate elevated cholesterol levels.

Causes

Cholesterol is transported through the bloodstream and bound to proteins. This mixture of proteins and cholesterol is known as lipoprotein. There are several forms of cholesterol, depending on what the lipoprotein contains. They are:

• Low-density lipoproteins (LDL). LDL, or "bad" cholesterol, carries cholesterol particles throughout the body. LDL cholesterol accumulates in your arteries, hardening and narrowing them.

• High-density lipoproteins (HDL). HDL, or "good" cholesterol, picks up excess cholesterol and transports it back to the liver.

Diagnosis

A lipid panel or lipid profile is a blood test that checks cholesterol levels and typically reports total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. In general, you must fast for nine to twelve hours before the test, ingesting no food or liquids other than water. Some cholesterol tests do not require fasting, so follow your doctor's directions.

Treatment

The first line of defence against high cholesterol is to improve your lifestyle by exercising and eating a healthier diet. However, if you've made these significant lifestyle changes and your cholesterol readings remain high, your doctor may recommend medication. Your age, health, potential drug side effects, and personal risk factors are all factors that influence the medication combination you choose. Medications include statins, PCSK9 inhibitors, bempedoic acid, bile acid-binding resins, and cholesterol absorption inhibitors.

Prevention

The same heart-healthy lifestyle choices can lower cholesterol and help you avoid getting high cholesterol in the first place. To help avoid high cholesterol, you can:

• Eat a low-salt diet that focuses on fruits, vegetables, and whole grains.
• Limit your intake of animal fats and use good fats in moderation.
• Lose excess weight and maintain a healthy weight
• Quit smoking
• Exercise at least 30 minutes every day of the week.
• Manage your stress.

Conclusion

Although high cholesterol is a major risk factor for cardiovascular disease, it can be effectively treated with a combination of medication and lifestyle changes. LDL (bad cholesterol) levels can be significantly reduced. In contrast, HDL levels can be increased by eating a heart-healthy diet, exercising regularly, maintaining a healthy weight, and avoiding tobacco and excessive alcohol. Statins and other cholesterol-lowering medications can help reduce cardiovascular risk for people who cannot achieve optimal control with lifestyle changes alone. Regular monitoring and consultation with doctors are essential for keeping cholesterol levels within normal ranges and improving cardiovascular health. People who take preventative measures can significantly lower their risk of developing heart disease and improve their overall health.
