What is a significant risk factor for severe maternal outcome in patients with hypertensive disorders in pregnancy?

A significant risk factor for severe maternal outcomes in patients with hypertensive disorders in pregnancy encompasses various elements, and each option presented contributes to an increased risk. Obesity has been linked to higher incidences of hypertension and preeclampsia, which can escalate the severity of maternal complications. It often leads to a pro-inflammatory state and increased vascular resistance, both of which are detrimental during pregnancy.

Age over 35 years also presents a notable risk, as advanced maternal age is associated with a greater likelihood of hypertensive conditions. Older mothers tend to experience increased risks for various pregnancy complications, including preeclampsia and gestational hypertension.

Multiple gestation significantly amplifies risks due to the increased demands on the mother's body, leading to heightened blood volume and greater likelihood of hypertensive disorders. The physiological changes and stressors associated with carrying more than one fetus can complicate the course of pregnancy.

In summary, the combination of obesity, advanced maternal age, and multiple gestation collectively elevates the risk for severe maternal outcomes, justifying the choice that all of these factors are significant contributors to the risk landscape for hypertensive disorders in pregnancy.
