One of the nurses told me I should start fasting which I don't understand because I'm not over weight I'm actually pretty healthy for my size. Im 5 feet and I weigh 108. Should I listen to them? They wanted me to fast for a week until my next appointment. Which I don't understand... And they expect me to drive myself back to the clinic.. Like I'm not gonna be feeling drowsy or weak. Idk.
You should have asked them why they wanted you to fast for a week! It is not normal for anyone to fast for a week other than possibly spiritual reasons. If you really wish to know why, please give them a call and ask them the purpose for the fast. Even if you were overweight, that would be a stupid reason for a week fast.
Ring the nurse and confirm exactly what is required.
Sometimes you need to do a fasting blood test a week later but you only need to fast for 12 hours before the test.
