why fasting is important when having blood work done
In: Biology
The digestion of food changes what’s in your blood, so it will affect the analysis. For example, eat a big meal and you’ll get a spike of glucose, then insulin will be secreted to counteract it, and gradually it goes back down. If you fast before every blood draw, you’re at the baseline levels and can make a fair comparison with what’s typical or with your previous results.
