What are normal cholesterol level numbers?
Cholesterol levels can be a reliable predictor of a person’s risk for heart disease. High levels of cholesterol in the blood have been found to increase the risk of developing heart disease, the leading cause of death in the United States. Therefore, it is crucial for individuals to understand their cholesterol numbers and what they represent.
What is cholesterol?
Cholesterol is a type of fat that is produced by the liver and is necessary for the body to function correctly. The body needs cholesterol to help build cells and produce hormones. However, high levels of cholesterol can be harmful and increase the risk of developing heart disease.
How is cholesterol measured?
Cholesterol is measured by a blood test, which takes a small sample of blood from the arm. The test measures the total amount of cholesterol in the blood, including low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides.
What are the normal ranges for cholesterol levels?
The normal ranges for cholesterol levels are:
- Total cholesterol: less than 200 milligrams per deciliter (mg/dL)
- HDL cholesterol: 60 mg/dL or higher
- LDL cholesterol: less than 100 mg/dL
- Triglycerides: less than 150 mg/dL
If your total cholesterol level is between 200 and 239 mg/dL, it is considered borderline high. A total cholesterol level of 240 mg/dL or higher is considered high.
What are LDL and HDL cholesterol?
LDL cholesterol is often referred to as “bad” cholesterol because it can build up on the walls of the arteries, leading to the formation of plaque. High levels of LDL cholesterol increase the risk of developing heart disease.
HDL cholesterol, on the other hand, is often referred to as “good” cholesterol because it helps remove LDL cholesterol from the arteries and carries it to the liver, where it can be processed and eliminated from the body. High levels of HDL cholesterol can help lower the risk of developing heart disease.
How can I improve my cholesterol levels?
There are several things you can do to help improve your cholesterol levels:
- Eat a healthy diet: Choose foods that are low in saturated fat and cholesterol and high in fiber.
- Exercise regularly: Regular physical activity can help raise HDL cholesterol levels and lower LDL cholesterol levels.
- Quit smoking: Smoking can raise LDL cholesterol levels and lower HDL cholesterol levels.
- Take medication: In some cases, medication may be necessary to help lower cholesterol levels.
What are the risk factors for high cholesterol?
Several factors can increase the risk of developing high cholesterol, including:
- A family history of high cholesterol or heart disease
- A diet that is high in saturated and trans fats
- Lack of physical activity
- Being overweight or obese
- Smoking
- Age (Cholesterol levels tend to increase with age)
What are the symptoms of high cholesterol?
High cholesterol does not typically cause any symptoms. Therefore, it is essential to have your cholesterol levels checked regularly by your healthcare provider. High cholesterol can only be detected through a blood test.
What are the complications of high cholesterol?
High cholesterol can lead to the formation of plaque on the walls of the arteries, which can increase the risk of developing heart disease. Over time, the buildup of plaque can cause the arteries to become narrow and decrease blood flow to the heart. If a blood clot forms and blocks an artery, it can cause a heart attack or stroke.
Conclusion
Knowing your cholesterol levels and working to maintain a healthy cholesterol level is crucial to keeping your heart healthy. A healthy diet, regular exercise, not smoking, and taking medication if necessary can all help improve your cholesterol levels and lower your risk of developing heart disease.
