What is Cholesterol?
Cholesterol is a waxy, fat-like substance that is found in all of the cells in your body. It is essential for the proper function of the body, as it is used to make cell membranes, hormones, and vitamin D. However, high levels of cholesterol can increase the risk of heart disease, stroke, and other health problems.
There are two types of cholesterol:
- Low-density lipoprotein (LDL) is also known as "bad" cholesterol. LDL cholesterol can build up in the walls of the arteries and form plaque. This plaque can narrow the arteries and make it harder for blood to flow. Over time, plaque can build up to the point where it blocks an artery completely, which can lead to a heart attack or stroke.
- High-density lipoprotein (HDL) is also known as "good" cholesterol. HDL cholesterol helps to remove excess cholesterol from the body and can actually lower the risk of heart disease.
What are the Causes of High Cholesterol?
There are several factors that can contribute to high cholesterol, including:
- Diet: A diet high in saturated and trans fats can raise LDL cholesterol levels. Saturated fats are found in animal products, such as meat, poultry, and dairy products. Trans fats are found in some processed foods, such as cookies, crackers, and fried foods.
- Physical activity: Lack of physical activity can raise LDL cholesterol levels and lower HDL cholesterol levels.
- Obesity: Being overweight or obese can increase LDL cholesterol levels and lower HDL cholesterol levels.
- Smoking: Smoking can raise LDL cholesterol levels and lower HDL cholesterol levels.
- Family history: If you have a family history of high cholesterol, you are more likely to have high cholesterol yourself.
How is Cholesterol Checked?
Cholesterol levels can be checked with a simple blood test. Your doctor will likely recommend that you have your cholesterol checked every 4-6 years starting at age 20. If you have risk factors for high cholesterol, you may need to have your cholesterol checked more often.
How Can I Lower My Cholesterol?
There are several things you can do to lower your cholesterol, including:
- Eat a healthy diet: This includes eating a variety of fruits, vegetables, and whole grains. You should also limit your intake of saturated and trans fats.
- Get regular physical activity: Aim for at least 30 minutes of moderate-intensity physical activity most days of the week.
- Lose weight: If you are overweight or obese, losing even a small amount of weight can help to lower your cholesterol.
- Quit smoking: If you smoke, quitting will help to lower your cholesterol.
- Take medication: If lifestyle changes are not enough to lower your cholesterol, your doctor may prescribe medication.
Managing High Cholesterol
If you have high cholesterol, it is important to work with your doctor to develop a treatment plan. This plan will likely include lifestyle changes, such as eating a healthy diet and getting regular physical activity. In some cases, medication may also be prescribed.
By following your treatment plan and making healthy lifestyle choices, you can help to lower your cholesterol and reduce your risk of heart disease and other health problems.
Here are some additional tips for managing high cholesterol:
- Read food labels carefully: Pay attention to the amount of saturated and trans fats in the foods you eat.
- Choose lean protein sources: Choose lean meats, poultry, and fish.
- Cook with healthy fats: Use olive oil, canola oil, or peanut oil instead of butter or shortening.
- Add soluble fiber to your diet: Soluble fiber can help to lower LDL cholesterol. Good sources of soluble fiber include oats, beans, and lentils.
- Limit alcohol intake: Alcohol can raise LDL cholesterol levels.
- Manage stress: Stress can raise cholesterol levels. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
By following these tips, you can help to lower your cholesterol and improve your overall health.
