A 21-year-old young lady presents with gestational diabetes. Her blood glucose is not in control after dietary measures. Out of the following dugs which should be the treatment option for her?

For a 21-year-old with gestational diabetes whose blood glucose is uncontrolled by diet, the primary treatment option is insulin therapy. Insulin does not harm the baby and is generally the preferred medication for gestational diabetes. Other oral medications like metformin may be considered, but insulin is the standard treatment for cases that aren't responsive to diet and exercise alone.
