Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? What is the normal blood pressure range for pregnant women?Doctor's answer:
The blood pressure of pregnant women is not significantly different from that of the general population. However, in the early and middle stages of pregnancy, blood pressure tends to be slightly lower, while in the late stages, it may be mildly elevated. Generally, systolic blood pressure remains unchanged, while diastolic blood pressure may slightly decrease due to peripheral vasodilation, blood dilution, and the formation of arteriovenous shunts by the placenta. A pregnant woman's normal blood pressure should not exceed 130/90 mmHg, or be more than 30/15 mmHg higher than her baseline blood pressure. If it exceeds these levels, it should be considered pathological. For individuals with a lower baseline blood pressure, if their systolic blood pressure increases by more than 30 mmHg or their diastolic blood pressure rises by more than 15 mmHg during the later stages of pregnancy, this is also abnormal. Therefore, pregnant women should check and understand their baseline blood pressure during early pregnancy, as it cannot be generalized.
