What is Low BP in Pregnancy?

Blood pressure is the strength with which your heart pumps blood around your body. This pumping of blood is vital as it provides nourishment and oxygen to every cell. When the pressure is low, it is called low blood pressure or hypotension. Low blood pressure is a normal condition during pregnancy as it is caused by changes in pregnancy hormones and variations in blood circulation.

Appropriate blood pressure is needed by the body to ensure proper blood flow to the organs. The reading of healthy blood pressure is 120 mm hg/80 mm hg. Any reading below 90 mmhg/60 mm hg is considered low blood pressure. The readings of low blood pressure vary from person to person. Typically, a drop of 5 mm hg to 10 mm hg in systolic pressure and 15 mm hg in diastolic pressure is seen in most women.
