What maternal condition can result from excessive weight gain in pregnancy?

Excessive weight gain during pregnancy can lead to increased blood pressure and hypertension. This condition, often referred to as gestational hypertension, can pose serious risks for both the mother and the developing fetus. When a pregnant individual gains more weight than is recommended, it increases the demand on their cardiovascular system, which can result in elevated blood pressure levels.

Hypertension in pregnancy may progress to more severe conditions, such as preeclampsia, characterized by high blood pressure and damage to other organ systems, typically the liver and kidneys. Managing weight gain through a balanced diet and appropriate physical activity can be essential for maintaining healthy blood pressure levels during pregnancy, thus reducing the risk of complications associated with hypertension.

In contrast, the other options do not accurately reflect the consequences of excessive weight gain in pregnancy. For example, reduced risk of gestational diabetes and decreased fatigue are unlikely to result from excessive weight gain; rather, these conditions are more commonly associated with poor weight management and overall maternal health. Hyperthyroidism is not directly correlated with weight gain in pregnancy and is a separate endocrine condition.
