Which of the following conditions may require close monitoring during pregnancy?

High blood pressure and diabetes are conditions that can significantly impact both the health of the pregnant individual and the developing fetus. During pregnancy, these disorders can lead to complications such as preeclampsia, gestational hypertension, or uncontrolled blood sugar levels, which can increase the risk of birth defects, preterm birth, and other serious health issues.

Close monitoring involves regular check-ups to track blood pressure levels and manage blood glucose levels to ensure both maternal and fetal health are maintained. Interventions or lifestyle adjustments may be necessary depending on the severity of these conditions. In contrast, conditions like the common cold, seasonal allergies, and simple headaches typically do not require the same level of monitoring, as they are usually less concerning for complications in pregnancy and can often be managed with standard care or over-the-counter treatments.
