To understand the potential risks of high cholesterol, it helps to understand the role cholesterol plays in our bodies. Here’s some helpful information, courtesy of the National Institutes of Health.
Cholesterol is a waxy, fat-like substance that’s found in all cells of the body.
Your body needs cholesterol to make vitamin D, produce certain hormones, and generate substances that help you digest foods. Your body makes all the cholesterol it needs. However, cholesterol is also found in some of the foods you eat.
Cholesterol travels through your bloodstream in small packages. These packages are made of fat (lipid) on the inside and proteins on the outside.
Two kinds of packages carry cholesterol throughout your body: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Having healthy levels of both types is important.
LDL cholesterol sometimes is called “bad” cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries.
HDL cholesterol sometimes is called “good” cholesterol. This is because it carries cholesterol from other parts of your body back to your liver. Your liver then removes the cholesterol from your body.
The higher the level of LDL cholesterol in your blood, the GREATER your chance is of getting heart disease. The higher the level of HDL cholesterol in your blood, the LOWER your chance is of getting heart disease.
According to WebMD, high cholesterol may be due to weight gain, eating foods high in saturated fat (an unhealthy fat found in most animals, their byproducts and some plants), trans fats (another unhealthy form of fat), and cholesterol. Lifestyle factors like smoking or not exercising also add to your risk. Exercising or eating a heart-healthy diet may be enough to lower cholesterol, but for some people, high levels of LDL run in the family, and changing how they eat or exercise may not be enough.1
Triglycerides, the most common fat found in the body, can also lead to heart disease. Low HDL, high LDL, and high triglycerides may speed up the fatty buildup in your arteries. And, just like cholesterol, triglycerides are affected by age, gender, family, health and lifestyle.2
Controlling your cholesterol may take some work, but exercising regularly and watching what you eat are great first steps. WebMD offers these simple tips for lowering your cholesterol:
Above all, take charge of your health! Even if your cholesterol levels are good, healthy habits will help keep them that way.
For some people, diet and exercise aren’t enough to get their numbers down, but your doctor can help:
