Hypertensive Disorders of Pregnancy – A Must Read!
PIH is thought to be due to an imbalance between the production of vasopressin (ADH) and prostaglandin E2. Both these hormones cause blood vessels to constrict, so when too much vasopressin is produced, it causes constriction in the vessels, leading to low blood flow. The most common symptoms of PIH are mild to moderate swelling of the hands and feet, weight gain, nausea and vomiting. A pregnant woman with these symptoms should consult her doctor as soon as possible because it can lead to severe complications such as preeclampsia (Hypertension), HELLP syndrome (hemolysis, elevated liver enzymes and low platelets) or placental abruption.
Let us discuss each type in detail.
Chronic Hypertension in pregnancy
Chronic Hypertension is a condition of high blood pressure that has been present for more than three months before pregnancy or in the past. It is also known as chronic systemic Hypertension, pre-existing Hypertension or essential Hypertension. If a woman has chronic Hypertension before becoming pregnant, it will usually remain untreated during pregnancy and may not require any treatment.
However, if it develops during pregnancy, then treatment may be necessary. It is important to note that blood pressure during pregnancy is usually higher than measured before pregnancy, as it increases due to the growing uterus and placenta. Women should be treated with anti-hypertensive medications.

Gestational Hypertension is a disorder that affects women during pregnancy. It shares many of the same signs and symptoms as high blood pressure caused by pregnancy, but it occurs earlier in a woman’s pregnancy (it may be present before she knows she is pregnant). There is no established reason for gestational Hypertension, but it is thought to result from the hormonal changes that occur during pregnancy. When you are pregnant, your body produces more estrogen and progesterone. These hormones relax the blood vessels in the mother’s body so more blood can travel through them.
This increase in blood flow can make the mother’s blood pressure rise. In some women, this rise in blood pressure is temporary and goes away after delivery. However, women with gestational Hypertension may have high blood pressure for a more extended period or permanently after their pregnancy ends. This is necessary for the mother to provide nutrients and oxygen to the growing fetus. When these hormones are overproduced, they can cause blood vessels in your body to dilate too much and make them too relaxed.

High blood pressure may also accompany preeclampsia, a condition that can appear during pregnancy. It’s caused by problems with the placenta and often develops later in pregnancy. Receiving treatment as soon as possible is crucial since preeclampsia can lead to significant health issues for both mother and child. The condition can develop at any stage of pregnancy, but it’s most common in the third trimester. Preeclampsia is also known as toxemia and eclampsia. It’s also associated with premature birth and stillbirth.

1. Symptoms of HELLP
If you encounter any of these symptoms during pregnancy, contact your doctor immediately so they can make sure that you are not experiencing HELLP syndrome.
2. HELLP Syndrome Diagnosis and Treatment
HELLP syndrome is diagnosed through a combination of blood tests, physical examination, and ultrasound.
Blood tests are used to measure two types of proteins:
LDH (lactate dehydrogenase)
AST (aspartate transaminase)
Eclampsia is a complication of pregnancy that affects about 2% of pregnancies. It is characterized by seizures, which can be either convulsions (usually tonic-clonic movements) or absence seizures. Eclampsia is also associated with high blood pressure and protein in the urine.
1. Symptoms of Eclampsia
Eclampsia is a severe condition that occurs in pregnant women. It can lead to seizures, strokes, and even death. There are several symptoms of eclampsia, including:
2. Eclampsia Diagnosis and Treatment
Eclampsia is diagnosed based on symptoms and medical history. A doctor will ask questions about your symptoms and perform a physical exam to determine if you have eclampsia.
If the doctor suspects that you have eclampsia, they may order tests to confirm their diagnosis. These may include:
a. Blood tests
Blood tests can help determine if the level of protein or sugar in your blood is abnormal. They can also check for signs of infection or bleeding problems.
This test checks for signs of kidney damage, such as increased creatinine levels or blood in the urine.
c. CT scan
This test uses X-rays and computer technology to produce images of internal tissues, bones, fat, and organs. These scans may be used to look for signs of brain hemorrhage or stroke in people with eclampsia.
3. Eclampsia Diagnosis and Treatment
In conclusion, although many pregnant women with high blood pressure have healthy babies without serious problems, high blood pressure can be dangerous for both the mother and the fetus. Some women develop high blood pressure while they are pregnant (often called gestational Hypertension), which is related to pre-existing chronic high blood pressure in some cases.
However, complications with the pregnancy are usually not caused by gestational Hypertension alone but by pre-existing chronic high blood pressure as well.
Frequently Asked Questions
Hypertension is a condition in which your blood pressure is elevated, which affects almost half of all adults nowadays.
Hypertension in pregnancy, also called gestational Hypertension, typically refers to high blood pressure that develops during pregnancy. It’s important to note that this condition differs from preeclampsia, a more serious condition with additional symptoms.
You should maintain a healthy weight to reduce your blood pressure. Eating a balanced diet, including lots of fruits and vegetables, and exercising regularly are sure ways to control your blood pressure during pregnancy.
Normal blood pressure in pregnancy is considered to be a systolic blood pressure (the top number) of less than 120 mmHg and a diastolic (the bottom number) of less than 80 mmHg.
Diastolic Hypertension is caused by a narrowing of the arteries, which reduces blood flow to the heart. Sometimes this narrowing can be caused by high cholesterol or high blood pressure.
