A 48-year-old woman who has had Type 2 diabetes mellitus for several years is seen for a routine follow-up evaluation. Her metabolic control has always been very good, with most hemoglobin A1c values less than 6.5%. Her current treatment is metformin 850 mg twice daily. She self-monitors her blood glucose two to three times daily and usually checks random 2-hour postprandial glucose values at least once daily. She notes that her postprandial glucose levels have been above her target of less than 160 mg/dL (8.88 mmol/L) for several weeks, despite increasing her activity level by walking three or four times weekly after dinner. Her body mass index is 29.2. Her blood pressure is 128/86 mm Hg, and her A1c value is 7.2%. Self-monitored blood glucose values from the past week are noted in her log as follows: BLOOD GLUCOSE VALUE, mg/dL Breakfast Lunch Dinner Day Pre Post Pre Post Pre Post Bedtime Comments Sun 96 109 132 — — — Ate pastry Mon 114 207 — — 97 178 — Walked Tue — — — — 136 217 — — Wed 91 235 — 99 83 — — Walked Thu 89 — 121 118 — 261 — — Fri 76 — — — 78 188 — Walked Sat 79 194 — — 148 — — — Pre = preprandial; post = 2-hour postprandial.
