A twenty-nine-year-old man with diabetes mellitus type one uses a basal–bolus insulin regimen with once daily long-acting insulin at bedtime and rapid-acting insulin before meals. He brings a two-week home log of capillary blood glucose readings. Most fasting morning values are between 55 and 65 milligrams per deciliter. Midday and evening values are generally between 100 and 150 milligrams per deciliter, and he has had no daytime episodes of low blood sugar. He denies missed meals or extra rapid-acting insulin. What is the most appropriate adjustment to make first in primary care?
