1. What is preeclampsia?

Preeclampsia, formerly known as toxemia of pregnancy, is a condition in which pregnant women have elevated blood pressure, protein in the urine, and swelling of the legs and arms. Preeclampsia, which can range from mild to severe, usually occurs in the last months of pregnancy, although it can also occur in the early months or after birth.
Preeclampsia can lead to eclampsia, a condition that endangers the health of the mother and baby, and in rare cases can cause death, stillbirth. The only cure for preeclampsia is childbirth. However, even after delivery, symptoms of preeclampsia can last for 1 to 6 weeks or more.

Preeclampsia can occur as early as 20 weeks of pregnancy, but it is very rare. Symptoms usually begin after 34 weeks. In some cases, symptoms develop after birth, often within 48 hours of birth. They tend to go away on their own but can last up to 12 weeks after birth. In addition to swelling (also called edema), protein in the urine, and increased blood pressure, symptoms of preeclampsia include:
Weight gain in 1 or 2 days due to increased fluid in the body Abdominal pain, especially in the upper right side Severe headache Reflex changes Little or no urination Dizziness Severe vomiting and nausea Vision changes: loss of vision, sensitivity to light, blurred vision. Some women with preeclampsia don't have any symptoms, so it's important to see your doctor for regular blood pressure checks and a complete pregnancy urine test.

Mild preeclampsia affects 6% of pregnancies, and severe cases develop in about 1 to 2% of pregnancies. There are a number of factors that can increase your chances of developing preeclampsia, such as:
Having diabetes, high blood pressure or kidney disease before you get pregnant Have another medical condition, such as diabetes lupus or antiphospholipid syndrome Having had preeclampsia in a previous pregnancy Other factors that may slightly increase your risk of developing preeclampsia include:

Although most cases of preeclampsia cause no problems and improve soon after the baby is born, there is a risk of serious complications that can affect both mother and baby.
Preeclampsia can cause the placenta to not receive enough blood, which can cause your baby to have a very low birth weight, also known as fetal growth restriction.
It is also one of the most common causes of premature birth and subsequent complications for babies, including learning disabilities, epilepsy, cerebral palsy, and problems with hearing and vision.
Rare but potentially dangerous pre-eclampsia complications are as follows:
Stroke Convulsions Accumulation of fluid in the chest area Heart failure Bleeding after giving birth When pre-eclampsia or eclampsia damages the liver and blood cells , you may have a complication called HELLP syndrome . It stands for:

Hemolysis: This is a condition when the red blood cells that carry oxygen in your body break down. Elevated liver enzymes Low platelet counts: This is a condition when you don't have enough platelets, so your blood doesn't clot as it should. HELLP syndrome is a medical emergency. Call 911 right away if you have any of the following symptoms:
Blurred vision Chest or stomach pain Headache Fatigue Abdominal discomfort or vomiting Swelling of the face or hands Bleeding gums or nose Preeclampsia can also cause placental abruption A sudden separation from the uterus, called placental abruption, can lead to stillbirth.

If your baby isn't full-term, your doctor may treat mild preeclampsia until your baby has grown enough to be born safely. The closer to the due date, the better for the baby.
