Fasting before a blood test is a common practice that many people may not fully understand. The reason behind fasting is to get the most accurate results from the blood test. When you eat, your body absorbs nutrients and releases chemicals into the bloodstream. These can affect the results of certain tests, such as cholesterol and glucose levels.
Fasting for a blood test typically means abstaining from food and drink (except water) for 8-12 hours beforehand. This allows your body to return to a baseline state, giving healthcare professionals a clearer picture of your overall health.
So, next time your doctor asks you to fast before a blood test, remember that it is for your own benefit. It may be a small inconvenience, but it ensures that you receive the most accurate results possible.
