Cholesterol 101

Facts Every Adult Should Know

By: JenniferPalm

A waxy, fat-like substance

Produced naturally

in the body

- via the liver

Also consumed through your diet

What is Cholesterol?

Sources of cholesterol

Cholesterol Continued

It’s normal to have a certain amount of cholesterol in your body

In fact, it’s needed for good health

  • to produce cell membranes and various hormones

    But too much cholesterol can have a negative impact on your health

Types of Cholesterol

  • There are two different kinds:

    • Low-density lipoproteins (LDL)

      • Often referred to as “bad”


    • High-density lipoproteins (HDL)

      • Often referred to as “good”


Types of Cholesterol Cont’d

Low-density lipoproteins

  • deliver cholesterol to the body

  • stick to the walls of the arteries – clogging them

    High-density lipoproteins

  • carry the LDL to the liver to be broken down

  • work to protect the arteries from plaque build up

Also known as hypercholesterolemia

Greatly increases your risk of having a heart attack or stroke

High Cholesterol

High Cholesterol Continued

Extra cholesterol in the blood

Builds up on the walls ofyour arteries

Causing arteries to narrow or harden

- a process known as atherosclerosis

Which can completely block an artery

High Cholesterol Continued

This picture illustrates how cholesterol builds up in your arteries over time.

High Cholesterol Continued

A blocked artery has the potential to be extremely life-threatening.

Contributing Factors

  • Diet

    • Consuming foods high in saturated/trans fats and dietary cholesterol

    • Includes:

      • Fast food

      • Fried food

      • Egg yolks

      • Meat

      • Dairy products

Contributing Factors Continued

  • Obesity

    • Major risk factor for heart disease

    • Usually due to an intake of foods high in saturated fats

  • Smoking

    • Another risk factor for heart disease and stroke

    • Reduces HDL and changes LDL

Contributing Factors Continued

  • Inactivity

    • Can lead to weight gain

      • Raising LDL cholesterol

  • Heredity

    • High cholesterol tends to run in families

      • Resulting in high levels of LDL

Contributing Factors Continued

  • Gender and Age

    • Men usually develop coronary artery disease earlier than women

    • Men tend to have lower HDL levels while women have higher LDL

    • Everyone’s LDL levels rise as they age

Contributing Factors Continued

  • Other Medical Conditions

    • There are other conditions that can also affect your cholesterol levels, including:

      • Kidney disease

      • Diabetes

      • Hypothyroidism

Recommended Values

If total cholesterol and LDL are higher than recommended values or if HDL is lower, you are at an increased risk for heart disease.

Cholesterol Testing

  • There are no signs and symptoms

  • So, get your blood cholesterol checked at least once a year by your physician

Cholesterol Testing Continued
