High blood pressure usually doesn’t have any symptoms. You will probably feel comfortable, even if you have high blood pressure. In some cases the signs and symptoms of include:
- A severe headache
- Swelling of face or hands. Feet may also swell, but many women have swollen feet during pregnancy. So swollen feet may not be considered as sign of a problem.
- Decreased levels of platelets in your blood (thrombocytopenia)
- Problems with vision, including temporary loss of vision, blurred vision or seeing spots
- Impaired liver function
- Excess protein in the urine (proteinuria) or additional signs of kidney problems
- Trouble breathing, caused by fluid in your lungs
- Nausea or vomiting
- Sudden weight gain
Problems of high blood pressure
High blood pressure during pregnancy can cause various problems for you and your baby, including:
- Premature delivery: When you have high blood pressure or preeclampsia during pregnancy, sometimes you may need to give birth early (before 37 weeks of pregnancy) to avoid serious health life threatening for you and your baby. Prematurity also can lead to breathing problems, increased risk of infection and other complications for the baby.
- Placental abruption: The placenta grows in the uterus and provides food and oxygen to the baby through the umbilical cord. High blood pressure increases your risk of placental abruption in which the placenta separates from the inner wall of you uterus before delivery. If this occurs, your baby would not get sufficient nutrients and oxygen in the womb. Severe abruption can cause heavy bleeding from the vagina, which can be serious for you and your baby.
- Low birth weight: High blood pressure can narrow blood vessels in the uterus, so the baby may not receive sufficient oxygen and nutrients which results in slow growth (intrauterine growth restriction) of the baby. In this case the weight of the newly born baby is usually less than 5 pounds, 8 ounces.
- Preeclampsia: Preeclampsia can be a serious medical condition in which a pregnant woman has high blood pressure that can affect most of her organs, like kidneys, brain and liver. Signs and symptoms of preeclampsia may include an abnormal amount of protein in the urine, severe headaches and changes in vision. A woman with serious preeclampsia will develop signs and symptoms such as abnormal kidney or liver function, changes in vision, low number of platelets in the blood, fluid in the lungs or a severe headache. In rare conditions, it can results in life-threatening conditions called eclampsia and HELLP syndrome. Eclampsia may causes seizures and can lead to coma. HELLP syndrome is related to serious blood and liver problems.
- Future cardiovascular disease: Having high blood pressure might increase your risk of future heart and cardiovascular (blood vessel) disease. Your risk of future heart disease is higher if you’ve had preeclampsia more than once in the past or you’ve had a premature birth due to having high blood pressure during child birth.
