Pregnancy poisoning is a serious condition that can significantly affect both maternal and fetal health during pregnancy. Medically known as preeclampsia, this condition is characterized by high blood pressure and signs of damage to various organs in the body. Many expectant mothers wonder “what is pregnancy poisoning?” or “what causes pregnancy poisoning?”, especially during the second and third trimesters. This condition can be brought under control with early diagnosis; however, if left untreated, it may pose life-threatening risks for both the mother and the baby. Therefore, regular prenatal check-ups throughout pregnancy are of great importance.

What Is Pregnancy Poisoning?


Pregnancy poisoning usually occurs after the 20th week of pregnancy and is a condition that may affect organs such as the kidneys, liver, and brain along with high blood pressure. During pregnancy, the amount of blood circulating in the body increases and blood vessels become more sensitive, making blood pressure harder to control in some women. When this increase is accompanied by findings such as protein leakage in the urine, the condition is referred to as preeclampsia. Since it is specific to pregnancy, recognizing the symptoms in a timely manner provides a major advantage in the treatment process.

High Blood Pressure


The most prominent sign of pregnancy poisoning is high blood pressure. Normally, blood pressure tends to be lower during pregnancy; however, in preeclampsia, blood pressure rising above 140/90 mmHg is considered a significant finding. Elevated blood pressure may cause symptoms such as headache, palpitations, and shortness of breath in the expectant mother. When an increase in blood pressure is detected, a medical evaluation by a doctor is essential.

Sudden Swelling of the Hands, Feet, and Face


While mild swelling during pregnancy is considered normal, sudden and pronounced edema may be an important warning sign of preeclampsia. Rapid swelling, especially in the face, ankles, or hands—particularly in the morning—indicates increased pressure within the blood vessels. This suggests a disruption in the body’s fluid balance.

Severe Headache


Severe and persistent headaches that may be confused with ordinary headaches are among the serious symptoms of pregnancy poisoning. Elevated blood pressure can affect the blood vessels in the brain, causing intense pressure and throbbing pain. When such headaches are accompanied by sensitivity to light and sound, urgent medical evaluation is required.

Visual Disturbances (blurred vision, light sensitivity)


Preeclampsia can affect the blood vessels in the eyes, leading to changes in visual quality. Complaints such as blurred vision, flashes of light, double vision, or dark areas in the visual field are considered serious symptoms. These signs may indicate progression of preeclampsia and require immediate medical attention.

Severe Pain in the Upper Abdomen (Right Upper Side)


Due to stretching of the liver capsule, a pressing pain may occur in the right upper abdomen. This pain is not related to eating and suggests that preeclampsia is affecting liver function. Pain that progressively worsens, makes breathing difficult, or radiates to the back should be taken seriously.

Sudden Weight Gain


Rapid fluid retention in the body may lead to noticeable weight gain within a short period of time. This increase is not due to fat accumulation but to fluid buildup. Such changes, which may even be noticeable within a single day, are among the warning signs of preeclampsia.

Protein in the Urine (Proteinuria)


One of the most important findings defining preeclampsia is protein leakage in the urine. When the kidneys are strained due to high blood pressure, the filtration system is disrupted and protein appears in the urine. This sign is highly valuable in diagnosing preeclampsia and can be detected quickly through regular urine tests.

Shortness of Breath


Disruption of the body’s fluid balance may cause fluid accumulation in the lungs. This can result in symptoms such as shortness of breath, chest tightness, or difficulty breathing. Shortness of breath is an emergency symptom that should be taken seriously.

Fatigue and General Feeling of Discomfort


Since pregnancy poisoning affects overall body functions, the expectant mother may experience marked fatigue, weakness, and lack of motivation. Unlike normal pregnancy-related tiredness, this condition is often described as “feeling unwell” in general.

Decrease in Baby’s Movements


Preeclampsia may affect blood flow in the placenta. When the supply of oxygen and nutrients to the baby decreases, fetal movements may slow down. This reduction may indicate an increased risk of growth restriction. Therefore, pregnant women should regularly monitor their baby’s movements and consult a doctor if they notice anything unusual.


Pregnancy poisoning is a condition that can be controlled with early diagnosis and regular follow-up but may lead to serious consequences if neglected. When symptoms such as high blood pressure, sudden swelling, severe headaches, or visual problems appear, prompt evaluation by a specialist is essential. The severity of preeclampsia symptoms may vary from one woman to another; therefore, personal sensations and changes should not be ignored. Regular prenatal check-ups, urine tests, and blood pressure monitoring are the most effective protective measures for both maternal and fetal health. Seeking professional medical support without delay when any symptom is noticed is vital.
