Pre-eclampsia is a serious pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. It typically begins after 20 weeks of pregnancy in women who previously had normal blood pressure.
While the exact cause is not fully understood, it is believed to be related to a problem with the placenta, the organ that nourishes the fetus. In pre-eclampsia, the blood vessels that supply the placenta may not develop properly, leading to a reduced blood supply. This can affect the mother's blood vessels and lead to high blood pressure and other symptoms.
Key Signs and Symptoms
The early signs of preeclampsia—high blood pressure and protein in the urine—are often detected during routine prenatal check-ups. You may not notice these signs yourself. As the condition progresses, more noticeable symptoms can develop, including:
- Severe headaches that do not go away with medication
- Vision changes, such as blurred vision, seeing flashing lights or spots, or temporary loss of vision
- Pain in the upper belly, usually under the ribs on the right side
- Nausea or vomiting (after the first trimester)
- Sudden weight gain or sudden swelling in the hands, face, or feet
- Shortness of breath
Risk Factors
While any pregnant woman can develop pre-eclampsia, certain factors can increase the risk, such as:
- Having a history of pre-eclampsia in a previous pregnancy
- Having chronic conditions like diabetes, high blood pressure, or kidney disease before pregnancy
- Being pregnant with multiples (twins, triplets, etc.)
- Being a first-time mother
- Having a family history of pre-eclampsia
- Being over 35 years old or having a BMI of 35 or more

Complications
Severe birth asphyxia
Fetal demise,
maternal death
Kidney failure.
If left untreated, pre-eclampsia can lead to serious complications for both the mother and baby, including:
- Eclampsia: The development of seizures in a woman with pre-eclampsia, which can be life-threatening.
- HELLP syndrome: A severe form of pre-eclampsia that stands for haemolysis (breakdown of red blood cells), elevated liver enzymes, and low platelet count.
- Placental abruption: When the placenta separates from the inner wall of the uterus before delivery, causing severe bleeding.
- Preterm birth
- Foetal growth restriction: The baby may not get enough oxygen and nutrients, leading to slow growth.
The only definitive cure for pre-eclampsia is delivering the baby. Treatment often involves close monitoring and medication to manage blood pressure, and in severe cases, an early delivery may be necessary to prevent further complications.
