Blood pressure changes in a pregnant woman are a physiological phenomenon. In the first and second trimesters, blood pressure drops, its lowest value usually occurs in the 23rd week of pregnancy. Subsequently, blood pressure begins to increase again and reaches the pre-pregnancy level by about 6 weeks after birth.
However, there are cases of hypertension in pregnant women and it is very dangerous both for the fetus and for herself. 5% - 10% of complications in pregnancy or childbirth are caused by untreated high blood pressure. Therefore, it is worth checking the pressure and in case of bad results, immediately contact the attending physician, and then the cardiologist.
