In regards to exercise during pregnancy, what is a major risk factor highlighted?

Severe preeclampsia is highlighted as a major risk factor in relation to exercise during pregnancy due to the significant health complications it poses for both the mother and the fetus. Preeclampsia is characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. When severe, it can lead to serious issues such as eclampsia (seizures), stroke, or organ failure.

In the context of exercise, engaging in physical activity with severe preeclampsia can exacerbate these risks, as exercise increases blood pressure and can put additional strain on an already compromised cardiovascular system. Therefore, women with severe preeclampsia are typically advised to avoid exercise and focus on medical management to ensure both their safety and that of their baby.

Well-controlled diabetes, mild preeclampsia, and moderate exercise typically present less of a risk and are managed differently; exercise can even be beneficial under appropriate circumstances with medical guidance for those conditions. These factors do not generally carry the same level of immediate concern or need for restriction as severe preeclampsia does.
