A well-known effect of insulin is to decrease the concentration of glucose in blood, which should make sense considering the mechanisms described above. Another important consideration is that, as blood glucose concentrations fall, insulin secretion ceases.
Bolus insulin provides coverage for mealtime spikes in blood glucose. Patients with type 2 diabetes who are taking basal insulin may find that their A1C remains elevated even when their fasting blood glucose levels are on target. This may result from inadequately controlled glucose spikes after meals.
