High Cholesterol

Dangers of Uncontrolled Blood Sugar

Cholesterol is a type of lipid. It’s a waxy, fat-like substance that your liver produces naturally. It’s vital for the formation of cell membranes, certain hormones, and vitamin D.
Cholesterol doesn’t dissolve in water, so it can’t travel through your blood on its own. To help transport cholesterol, your liver produces lipoproteins.
Lipoproteins are particles made from fat and protein. They carry cholesterol and triglycerides (another type of lipid) through your bloodstream. The two major forms of lipoprotein are low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
If your blood contains too much LDL cholesterol (cholesterol carried by low-density lipoprotein), it’s known as high cholesterol. When left untreated, high cholesterol can lead to many health problems, including heart attack or stroke.
High cholesterol typically causes no symptoms. That’s why it’s important to get your cholesterol levels checked on a regular basis. Learn what cholesterol levels are recommended for your age.

What High Blood Sugar Feels Like

LDL cholesterol, or “bad cholesterol”

Low-density lipoprotein (LDL) is often called “bad cholesterol.” It carries cholesterol to your arteries. If your levels of LDL cholesterol are too high, it can build up on the walls of your arteries.
The buildup is also known as cholesterol plaque. This plaque can narrow your arteries, limit your blood flow, and raise your risk of blood clots. If a blood clot blocks an artery in your heart or brain, it can cause a heart attack or stroke.

HDL cholesterol, or “good cholesterol”

High-density lipoprotein (HDL) is sometimes called “good cholesterol.” It helps return LDL cholesterol to your liver to be removed from your body. This helps prevent cholesterol plaque from building up in your arteries.
When you have healthy levels of HDL cholesterol, it can help lower your risk of blood clots, heart disease, and stroke. Learn more about HDL cholesterol.

Triglycerides, a different type of lipid

Triglycerides are another type of lipid. They’re different from cholesterol. While your body uses cholesterol to build cells and certain hormones, it uses triglycerides as a source of energy.
When you eat more calories than your body can use right away, it converts those calories into triglycerides. It stores triglycerides in your fat cells. It also uses lipoproteins to circulate triglycerides through your bloodstream.
If you regularly eat more calories than your body can use, your triglyceride levels can get high. This may raise your risk of several health problems, including heart disease and stroke.
Your doctor can use a simple blood test to measure your triglyceride level, as well as your cholesterol levels. Learn how to get your triglyceride level tested.

Tips

Pay attention to the saturated and trans fats on your food labels, as well as added sugars. The less of these you consume, the better. No more than 10 percent of your daily calories should come from either saturated fats or added sugars.
Don’t worry about eating enough cholesterol. Your body makes enough whether or not you consume it.
Eat more healthy, unsaturated fats. Try replacing butter with extra virgin olive oil in cooking, buy lean cuts of meat, and snack on nuts and seeds instead of french fries or processed snack foods.

High cholesterol symptoms

In most cases, high cholesterol is a “silent” problem. It typically doesn’t cause any symptoms. Many people don’t even realize they have high cholesterol until they develop serious complications, such as a heart attack or stroke.
That’s why routine cholesterol screening is important. If you’re age 20 years or older, ask your doctor if you should have routine cholesterol screening. Learn how this screening could potentially save your life.
