Chief Complaint

“I have had diabetes for about six months and would like to have my blood sugar tested. I think that my blood sugar is running low because I have a terrible headache.”

She has gained 10 lb over the past year. She monitors her blood sugar once a day, and her results have ranged from 215 to 280 mg/dL. Her fasting blood sugars have averaged 200 mg/dL.
