My daughter frequently complains of feeling sick, thirsty and hungry. She is 12 years old. After a shopping trip yesterday, she kept saying she was really thirsty and hungry and then became very rude until after she had eaten. As my sister is a nurse, I thought I would borrow the glucose monitor and check my daughter. After fasting of 11 hours, her glucose level was 6. I would be grateful for opinions. many thanks.
