What is Cholesterol?

  • Cholesterol is a waxy substance that is very similar to fat.
  • It helps your body create cell membranes and process the food you eat.
  • Cholesterol travels through your bloodstream in packets of fat and protein. These packets are called lipoproteins.

There are two major types of cholesterol:

  • High density lipoproteins (HDL cholesterol)
  • Low density lipoproteins (LDL cholesterol)

Meet the Family!

  • LDL cholesterol is bad for you. It clings to artery walls and builds up in plaque deposits.
  • (Not the good kind of deposit that you put in a bank – the bad kind of deposit that causes heart attacks).
  • HDL cholesterol is actually good for you. It moves other cholesterols out of the bloodstream and into the liver, where they are processed out of the body.

Measuring Cholesterol

  • After you turn 20, you should check your cholesterol at least once every 5 years.
  • To check your cholesterol levels, your doctor will do a lipoprotein profile.
  • Usually you have to fast before a lipoprotein profile.
  • That way, the doctor can measure the levels of HDL, LDL, and total cholesterol in your blood.

What you want from your cholesterol numbers…

  • Total cholesterol should be BELOW 200 mg/dL.
  • HDL cholesterol should be ABOVE 40 mg/dL.
  • LDL cholesterol should be BELOW 100 mg/dL.

Cholesterol  Risks

Certain factors increase your risk of getting high cholesterol, including…

  • Diet
  • Weight
  • Age
  • Gender
  • Heredity
  • Physical
  • Activity

In a nutshell…

  • If you’re overweight and don’t eat healthful foods, you’re at high risk.
  • Risk increases as you age, especially for women after menopause.
  • If high blood cholesterol runs in your family, you’re likely to get it too.
  • If you rarely exercise, your risk increases.

If any of the following elements are a part of your life, you are at even greater risk…

  • Diabetes
  • History of heart disease
  • Kittens
  • Smoking
  • High blood pressure
  • (We were kidding about the kittens)

Dangers of Cholesterol

  • LDL cholesterol builds up in your arteries, which clogs them over time.
  • If a clot gets stuck in an artery lined with plaque, it can cause a heart attack or stroke.
  • Sometimes the cholesterol in plaque deposits will burst, which causes clots of its own.
  • There are no symptoms of high cholesterol. It’s like a secret ninja assassin in your bloodstream. Which would be cool, if it weren’t so dangerous.

How to Lower Your Health Risks

  • Give yourself a little TLC. In this case, TLC stands for Therapeutic Lifestyle Changes. (Tender loving care won’t hurt either).
  • Keep saturated fats at less than 7% of what you eat each day.
  • Consume less than 200 mg of cholesterol daily.
  • Change your diet and increase your physical activity.
