What is a potential side effect of hyperglycemia during pregnancy?

Hyperglycemia during pregnancy can lead to a condition known as toxemia, which is characterized by high blood pressure and the presence of protein in the urine. This condition, also referred to as preeclampsia, can pose significant risks to both the mother and the developing fetus. When a pregnant woman experiences elevated blood sugar levels, it may disrupt normal metabolism and circulation, leading to complications such as swelling and increased blood pressure.

In contrast, the other options do not accurately represent the typical side effects associated with hyperglycemia during pregnancy. Dehydration may occur in different contexts but is not a direct result of hyperglycemia. Decreased appetite is also not a common consequence, as women with high blood sugar may actually experience increased thirst and hunger due to insulin resistance. Lastly, hyperglycemia increases the risk of complications rather than lowering it; thus, the correct association with toxemia highlights the serious implications of poor blood sugar management during this critical time.
