As advised by Babychakra expert Sonali Shivlani ( Prenatal) - Blood pressure causes edema which is swelling and also can result in dizzy spells. She should continue taking her medications so that the pressure does not suddenly spike. A sharp spike can even result in the placenta separating and this could be very dangerous for the fetus. In such a situation the doctor will want to deliver the baby via caesarean as soon as the doctor feels that the baby is ready.

if blood pressure is not normal and it vary all the time it will affect baby's health.u just tell her don't be tensed about delivery..thts y she's having high bp
