What dietary change may be required for a pregnant client with diabetes during the second half of her pregnancy?

For a pregnant client with diabetes, increased insulin during the second half of pregnancy is often necessary due to hormonal changes that impact insulin sensitivity and glucose metabolism. As pregnancy progresses, hormones such as human placental lactogen and cortisol can cause an increase in insulin resistance, making it more challenging to maintain optimal blood glucose levels.

As a result, the body may require more insulin to manage blood sugar effectively. This increased need can often be managed through adjusting insulin dosages under medical supervision. Maintaining stable blood glucose levels is crucial for the health of both the mother and the developing fetus, as uncontrolled diabetes can lead to complications such as macrosomia, preterm birth, and other health issues.

The other options, such as decreased protein intake, elimination of carbohydrates, and increased physical activity, do not directly address the specific need for insulin adjustments in the context of managing diabetes during pregnancy. Proper dietary management, including a balanced intake of carbohydrates, protein, and fats, along with the appropriate insulin regimen, is essential for the well-being of both the mother and the baby.
