From Bolivar, Missouri, USA:

My sister is 14 years old, 5 feet tall, and weighs 87 pounds. She has been diagnosed with diabetes mellitus, type 1. When she was tested her fasting blood sugar was 396 mg/dL and her urine sugar was 2% and acetone was found as well. Why is it that her potassium levels and chloride levels were elevated?

Also, what is the dawn phenomena and what causes it?


Potassium and Chloride are mineral elements in the blood that can go awry with diabetic ketoacidosis. The abnormalities are corrected with treatment of the DKA.

Dawn phenomenon is the tendency for glucose to go up in the early morning. This is useful. You wake up and need the energy. Also cortisol goes up in the early morning to help you get up. The cortisol tends to raise glucose and also to counteract insulin. People with diabetes tend to need a bit more insulin in the early morning. Without adequate amounts, the glucose goes up. Thus the dawn phenomenon.
