The effect of bedtime snacks on fasting blood glucose levels in gestational diabetes mellitus

A total of 68 women with gestational diabetes completed the trial, showing higher fasting blood glucose levels with bedtime snacks.

• Both higher carbohydrate and lower carbohydrate bedtime snacks resulted in increased fasting blood glucose levels compared to no snack.
• The mean fasting blood glucose level after a higher carbohydrate snack was 4.96 mmol/L, while it was 5.01 mmol/L after a lower carbohydrate snack.
• In contrast, the mean fasting blood glucose level without any snack was 4.87 mmol/L.
• The differences in fasting blood glucose levels were statistically significant, with p-values less than 0.001 for both snack types.
• These findings suggest that bedtime snacks may influence morning fasting blood glucose levels in women with diet-controlled gestational diabetes.
