What are the signs of high blood pressure during pregnancy? If you are afraid you have high blood pressure, you need to see a doctor. High blood pressure is dangerous. What could it cause? In the worst scenario, it could cause a stroke, heart attack or pre-eclampsia and premature delivery. What are the symptoms I need to be on the lookout for? You could see symptoms like visual disturbances. I feel that way when I’ve been throwing up so much I’m dizzy. You’d have blurred vision and sensitivity to light. You might also have headaches that won’t stop and the sound of blood rushing in your ears. I suppose a grocery store blood pressure monitor would be more certain. If you think your blood pressure is going up, you need to get to a doctor. Pre-eclampsia can be life threatening. How can I prevent it? In theory, having a healthy cardiovascular system and limiting salt intake help. In reality, we don’t have a good preventative measure. If only they could give me high blood pressure medicine to treat it. The only cure is delivering the baby, but that all too often leads to a stillbirth or preemie. I know that high blood pressure can ruin your kidneys, making pregnancy far worse than the regular literal bathroom runs the baby already causes. Prenatal diabetes raises the risk of high blood pressure, and pre-eclampsia has a strong correlation to it. Unlike the peeing in bleach test to determine a child’s gender. If you felt light headed or had blurred vision after that, it is due to chlorine fumes, not high blood pressure. How often does pre-eclampsia occur? High blood pressure shows up in around one in fifteen pregnancies, and your odds go up with age, obesity and having multiples. The only thing worse than multiples is multiple preemies. That is guaranteed to give you high blood pressure if you didn’t already have it.
