The increasingly low blood pressure of pregnant women may be physiological or pathological anemia, etc., which needs to be taken seriously.
1. Physiological factors: the lowering of blood pressure in some pregnant women may be due to physiological factors, because the dilation of peripheral blood vessels after pregnancy and the dilution of blood may result in the lowering of diastolic blood pressure, but most of the systolic blood pressure does not have any obvious changes, so there will be symptoms of low blood pressure, such as not accompanied by other manifestations, do not need special treatment and therapy.
2. Pathological factors: pregnant women’s blood pressure is getting lower and lower, also need to be highly suspected and anemia factors, at this time there will be a combination of dizziness and fatigue and other symptoms. Of course, persistent pressure on the inferior vena cava and lowering of the return blood volume can also cause vagus nerve excitation, resulting in lower and lower blood pressure.
It is recommended that pregnant women should take into account their own situation, so as to give appropriate treatment and therapy.
