Why is her fasting blood sugar high despite taking 20 units of Humalog and 2 mg of Pioglitazone at night?
Her fasting blood sugar may be high because Humalog is a rapid-acting insulin that works mainly around meal times and does not last long enough to control blood sugar overnight. Other factors may include diet, late-night snacks, delayed stomach emptying, stress, illness, or insufficient basal insulin. She should discuss this with her doctor, who may adjust her insulin or treatment plan to achieve better blood sugar control.
