Successful glycemic control using a flash glucose monitoring system for a pregnant woman with diabetes: a case report

Abstract

Background: Glucose control for pregnant women with glucose intolerance is important, as hyperglycemia may adversely affect the mother and the fetus.

Case presentation: We report the case of a pregnant Japanese woman who experienced gestational diabetes mellitus during her first pregnancy and developed impaired glucose tolerance after the delivery. During her second pregnancy with twins, she required up to 75 units of injected insulin to control her postprandial hyperglycemia and occasionally experienced hypoglycemia. We used a newly developed flash glucose monitoring system, which allowed her to successfully achieve ideal glycemic control and experience an uncomplicated delivery.

Conclusion: We suggest that this flash glucose monitoring system may be clinically effective for similar cases that involve pregnant women with abnormal glucose tolerance.

The results of continuous glucose monitoring using the sensor-based flash glucose monitoring system. The arrows indicate the timing of the patient’s meals and insulin injections. The numbers above the arrows indicate the numbers of the units for each insulin injection. The patient needed 57 units of injected insulin on day 8 (2200 kcal in 5 meals) (a), 43 units of injected insulin on day 10 (1960 kcal in 5 meals) (b), 35 units of injected insulin on day 17 (1960 kcal in 4 meals) (c), 18 units injected insulin on day 38 (1960 kcal in 4 meals) (d), and no injected insulin at 3 days after the delivery (2200 kcal in 3 meals) (e)
