                                Medical experts confirm that drinking plain water is not only permissible but recommended when fasting for a blood test. This is because water contains no calories or sugars that could skew the results, unlike other beverages. Knowing if you can drink water while fasting for FBS is key to ensuring an accurate blood glucose reading.
