It is essential to maintain good control of the insulin-treated (insulin‑dependent or gestational diabetes) patient throughout pregnancy.
Insulin requirements usually fall during the first trimester and increase during the second and third trimesters. Patients with diabetes should be advised to inform their doctors if they are pregnant or are contemplating pregnancy.
Careful monitoring of glucose control, as well as general health, is essential in pregnant patients with diabetes. Patients with diabetes who are lactating may require adjustments in insulin dose and/or diet.
