Cholesterol is a type of fat that is essential for the proper functioning of the body. It plays a vital role in the production of hormones, vitamin D, and other substances that are needed for healthy body function. However, having high levels of cholesterol in the blood can increase the risk of developing heart disease and stroke. Here’s what you need to know about cholesterol:
What is cholesterol?
Cholesterol is a waxy, fat-like substance that is found in all cells of the body. It is produced by the liver and is also present in certain foods such as meat, cheese, and eggs. There are two types of cholesterol: Low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol, and high-density lipoprotein (HDL) cholesterol, also known as “good” cholesterol.
Why is high cholesterol a concern?
High levels of LDL cholesterol can lead to a buildup of plaque in the arteries, which can narrow the blood vessels and reduce blood flow to the heart and brain. This can increase the risk of developing heart disease and stroke. High levels of HDL cholesterol, on the other hand, can help to protect against heart disease.
What are the risk factors for high cholesterol?
There are several risk factors that can increase the likelihood of having high cholesterol, including:
- Family history of high cholesterol or heart disease
- Being overweight or obese
- Eating a diet high in saturated and trans fats
- Lack of physical activity
- Smoking
- Age (cholesterol levels tend to increase with age)
Should you get your cholesterol checked?
If you have any of the risk factors for high cholesterol or have a family history of heart disease, it’s important to get your cholesterol levels checked. The American Heart Association recommends that adults over the age of 20 get their cholesterol levels checked at least once every 4 to 6 years. If you have high cholesterol, your doctor may recommend more frequent testing.
What can you do to lower your cholesterol?
If you have high cholesterol, there are several lifestyle changes you can make to help lower your levels, including:
- Eating a heart-healthy diet that is low in saturated and trans fats, and high in fruits, vegetables, whole grains, and lean protein
- Getting regular physical activity, such as brisk walking, for at least 30 minutes a day, most days of the week
- Quitting smoking
- Losing weight if you are overweight or obese
- Taking medication, such as statins, if recommended by your doctor
High cholesterol is a concern as it can increase the risk of heart disease and stroke. It’s important to get your cholesterol levels checked if you have any risk factors for high cholesterol, and to make lifestyle changes to lower your levels if they are high. Your doctor can help you develop a plan to manage your cholesterol and reduce your risk of heart disease and stroke.
