Fret not. How many times has it been checked. Is it consistently elevated? Is she talking treatment? If it is consistently above 140/90, then it needs to be brought down by medications. This will reduce the chances of her getting stroke heart attack and kidney damage. Thus knowing that someone has high BP is far better than not knowing. After all we could prevent problems. Your doctor will suggest some tests and commence medications if no is consistently elevated.
