  A general guideline is to fast for at least 8 to 12 hours for most blood tests.

• Hypoglycemia: Hypoglycemia, or low blood sugar, can occur when the body doesn’t have enough glucose to function properly. To mitigate this risk, make sure to eat a balanced meal that includes complex carbohydrates, protein, and healthy fats before fasting for blood work. You can also try to take a snack or meal with you when you go to the lab to help keep your blood sugar levels stable.

“I fasted for 12 hours before my blood work, and I experienced severe dehydration and dizziness,” said one patient who spoke to the Journal of Medical Ethics. “I wish I had known about the risks of fasting before my blood work and would have taken steps to mitigate them.

Common Misconceptions About Fasting for Blood Work

Communicating with Healthcare Providers

When fasting for blood work, it’s essential to communicate with your healthcare provider about any potential risks or side effects you may be experiencing. Be sure to ask questions like “What are the potential risks of fasting for blood work?” and “How can I mitigate these risks?” Additionally, make sure to provide your healthcare provider with information about any medications or medical conditions you may have.

“I make sure to let my healthcare provider know about any medications or medical conditions I may have before fasting for blood work,” said one patient who spoke to the Journal of Medical Ethics. “This way, we can work together to manage any potential risks or side effects that may arise.”
