When it comes to getting a cholesterol test, you’re typically instructed to fast for 9-12 hours beforehand. But what happens if you don’t fast? Can it still accurately measure your cholesterol levels?
Understanding Cholesterol and Fasting
Cholesterol is a waxy, fat-like substance found in all cells of the body. It’s essential for many bodily functions, including hormone production and digestion. However, high levels of cholesterol can increase the risk of developing cardiovascular disease, such as heart attack and stroke.
Fasting helps to lower cholesterol levels in the blood, as the body relies on stored fat for energy instead of dietary fat. This makes it easier to get an accurate reading of your fasting cholesterol levels.
Impact of Not Fasting on Cholesterol Test Results
If you don’t fast before a cholesterol test, the results may be higher than they would be if you had fasted. This is because food can contain cholesterol and other substances that can interfere with the test.
According to the National Cholesterol Education Program (NCEP), not fasting can increase total cholesterol levels by 4-15%, LDL cholesterol levels by 5-18%, and HDL cholesterol levels by 1-5%.
