Before knowing whether you can drink water while fasting, let us understand why you have to fast before some blood tests. The things you drink and eat can go into your blood and affect the result of some blood tests.

Usually, you have to dast before going for a blood sugar test. You also need to fast before a lipid profile test, which measures different kinds of cholesterol and triglycerides. There might be other tests that need fasting too.

Can I Drink Water When Fasting?

Yes, you can drink water when fasting if it is completely fine. In fact, water is the only thing you can have while fasting. Drinking water can help you feel better while fasting, and it makes it easier for the lab technician to take your blood. Your blood is made up of 50% water, so when you are hydrated, it is easier to find your veins and take the blood out.

How Long Do I Need to Fast?

Before getting your blood lipid or sugar profile checked, your doctor may ask you to fast for up to 8 hours. However, your doctor may have different instructions for you, so it is important to follow their recommendations whenever you can.

You can drink or eat something right after your blood is taken, so it is a good idea to bring a snack with you. It is also a good idea to schedule your blood test in the morning, so you will spend most of the fasting time when you are sleeping.

Should I Take My Medications When Fasting?

Often, you should keep taking your medicines as usual when fasting unless your doctor says otherwise. If you take any supplements like minerals or vitamins, ask your doctor for advice. Only make sure you do not mix up your medicine schedule or forget to take any important medicines during the fast time.
