Which class of medications can be used to manage gestational diabetes?

Insulin is the primary and most effective class of medication used to manage gestational diabetes. This condition occurs when a woman develops high blood sugar levels during pregnancy, and insulin helps to regulate glucose levels effectively. Unlike oral medications, insulin does not cross the placenta, making it a safer option for the fetus while allowing the mother to maintain appropriate blood sugar levels.

While other classes of medications may be used to manage diabetes in non-pregnant populations, they are not typically recommended during pregnancy due to concerns about safety for both the mother and the developing fetus. For instance, biguanides such as metformin can be considered in some cases, but insulin remains the first-line treatment because of its established safety profile during pregnancy. Thus, insulin's unique properties and effectiveness in controlling blood sugar levels make it the preferred choice for managing gestational diabetes.
