What is cholesterol?
Cholesterol is a waxy substance your liver produces to protect nerves and to make cell tissue and certain hormones. Your body also gets cholesterol from the food you consume. This includes eggs, meats, and dairy. Too much bad cholesterol (LDL) can be bad for your health. There is "good" (HDL) cholesterol and "bad" (LDL) cholesterol
What is the difference between "good" cholesterol and "bad" cholesterol?
Good cholesterol is called high-density lipoprotein (HDL). It removes cholesterol from the bloodstream. Low-density lipoprotein (LDL) is the "bad" cholesterol.
If your total cholesterol level is high because of a high LDL level, you might be at higher risk of heart disease or stroke. However, if your total cholesterol level is high only because of a high HDL level, you're probably not at higher risk.
Triglycerides are another kind of fat in your blood. When you consume more calories than your body can use, it turns the additional calories into triglycerides.
Altering your lifestyle (diet and exercise) can improve your cholesterol levels, decrease LDL and triglycerides, and increase HDL.
Your ideal cholesterol level will depend on your risk for heart disease.
Symptoms of high cholesterol
Oftentimes, there are no specific symptoms of high cholesterol. You could have high cholesterol and not know it.
If you have high cholesterol, your body may store the extra cholesterol in your arteries. These are blood vessels that carry blood from your heart to the rest of your body. A buildup of cholesterol in your arteries is known as plaque. Over time, plaque can become hard and make your arteries narrow. Large deposits of plaque can completely block an artery. Cholesterol plaques can also break apart, resulting in formation of a blood clot that blocks the flow of blood.
A blocked artery to the heart can lead to a heart attack. A blocked artery to your brain can result in a stroke.
Many people don't discover that they have high cholesterol until they experience one of these deadly events. Some individuals find out through regular check-ups that include blood tests.
What causes high cholesterol?
Your liver makes cholesterol, but you also get cholesterol from food. Consuming too many foods that are high in fat can increase your cholesterol level.
Being overweight and inactive also causes high cholesterol. If you are overweight, you probably have a higher level of triglycerides. If you never exercise and are not active in general, it can lower your HDL (good cholesterol).
Your family history also impacts your cholesterol level. Research has shown that high cholesterol tends to run in families. If you have an immediate family member that has it, you could have it, also.
Smoking also causes high cholesterol. It lowers your HDL (good cholesterol).
How is high cholesterol diagnosed?
You can not know if you have high cholesterol without having it checked. A simple blood test will show your cholesterol level.
Men 35 years of age and older and women 45 years of age and older should have their cholesterol checked. Men and women 20 years of age and older that have risk factors for heart disease should have their cholesterol checked. Teenagers may need to be checked if they are taking certain medicines or have a strong family history of high cholesterol. Ask your physician how frequently you should have your cholesterol checked.
Risk factors for heart disease include:
High cholesterol treatment
If you have high cholesterol, you might need to make some lifestyle adjustments. If you smoke, stop. Exercise on a regular basis. If you're overweight, losing just 5 to 10 pounds can improve your cholesterol levels and your risk for heart disease. Be sure to eat plenty of fruits, vegetables, whole grains, and fish.
Depending on your risk factors, your physician may prescribe medicine and lifestyle adjustments.
