A member asked:

Is it okay to drink water when fasting for blood work?

A doctor has provided 1 answer

Yes: Drinking water is fine unless directed specifically by your physician to avoid it. Fasting lab is looking for blood sugar and cholesterol which would be affected by coffee, food, and milk. I usually recommend to my patients to take their routine meds even when fasting except for medications that would affect the blood sugar.
