Cholesterol Levels

Know Your Cholesterol Levels


Our bodies can produce approximately 400 times more cholesterol than you could eat from 100 grams of butter. Together, the cholesterol your body makes and what you take in from what you eat  make up the total cholesterol level in the body.

Cholesterol Testing

There are no signs or symptoms of high cholesterol, thus the only way to know whether you have high cholesterol levels is to have your physician or pharmacist carry out a blood test. The test checks for HDL, LDL and triglycerides. 

It is worth noting that over the counter testing kits test only total cholesterol levels. The results of these tests should only be used as a guide and irrespective of the result you should still consult your physician.

The American Heart Association recommends that people aged 20 or older should test their cholesterol levels every 5 years. It is normal for cholesterol levels to fluctuate so repeat the test after one or two months to get a reliable average.

Test Conditions

It is recommended to fast 12 hours before the blood test so that food doesn’t falsely increase your cholesterol levels. Factors that can affect blood cholesterol levels temporarily are exercise and eating.

Eating before a test can raise cholesterol levels by more than 15%. A good idea is to schedule your blood test for early in the morning.
