Final answer:
Gestational diabetes is primarily treated through lifestyle modifications and, if needed, medication or insulin therapy to control blood glucose levels.
Step-by-step explanation:
The two main treatment methods for gestational diabetes are lifestyle changes and medication (including insulin therapy). Lifestyle changes such as a healthful diet, regular physical activity, and moderate weight loss can help control blood glucose levels. When these changes are insufficient, medication may be prescribed to enhance insulin release or effect. If still uncontrolled, insulin injections may be necessary to maintain blood glucose levels within a normal range. Controlling blood glucose levels is essential to prevent complications for both the mother and the developing fetus.
