# What Does HELLP Syndrome Mean in Pregnancy and How to Recognize It Early HELLP syndrome is a seri
Pregnancy is for most women a joyful period full of anticipation, but also a time when increased attention to one's health is necessary. Among complications that are not talked about enough, yet can have serious consequences, is HELLP syndrome – a condition that can surprise with both the speed of its onset and the severity of its symptoms. Although it is a relatively rare complication, it is a medical case that requires immediate attention and care.
The name HELLP is not coincidental – it is an acronym composed of words describing three key abnormalities: Hemolysis (breakdown of red blood cells), ELevated Liver enzymes, and Low Platelets. It is precisely this combination that makes HELLP syndrome a dangerous condition that can threaten both the mother and the unborn child. The syndrome was first described in 1982 by American gynecologist Louis Weinstein, who noticed that some pregnant women suffered from a specific combination of laboratory findings that could not be classified under any then-known diagnosis.

Who is most at risk and why HELLP develops
HELLP syndrome most commonly appears in the third trimester of pregnancy, typically between weeks 27 and 37, but it can occur earlier or even shortly after delivery. According to available data from the World Health Organization, severe preeclampsia and its associated complications affect approximately 2–8% of all pregnancies worldwide, with HELLP syndrome representing one of its most serious forms.
The exact cause of HELLP syndrome has not yet been fully clarified, but experts agree that the placenta and the way it implants into the uterine wall in early pregnancy play a key role. If this process does not proceed correctly, impaired blood flow to the placenta occurs, triggering a cascade of inflammatory reactions throughout the mother's body. These gradually damage the blood vessels, liver, and blood system. It is therefore a systemic disease that, while originating in the placenta, manifests across the entire organism.
Women at higher risk of developing HELLP syndrome include those who have previously experienced preeclampsia or HELLP syndrome in a prior pregnancy, women with chronic high blood pressure, diabetics, women with kidney disease or autoimmune conditions. First-time mothers and women over 35 are also at higher risk, but it is important to emphasize that HELLP syndrome can affect even a completely healthy woman with no prior risk factors. It is precisely this unpredictability that makes it particularly insidious.
The symptoms that need to be taken seriously are unfortunately often mistaken for common pregnancy discomforts. Pain in the upper abdomen or below the right rib cage, nausea, vomiting, general fatigue and malaise – all of these are manifestations that many pregnant women attribute to the normal course of pregnancy. This is precisely why HELLP syndrome is often diagnosed late, which significantly worsens the prognosis. As Professor Baha Sibai, one of the world's leading experts on preeclampsia, noted: "HELLP syndrome is a masquerader – its symptoms are so non-specific that we can easily miss it until it is too late."
How to recognize and diagnose HELLP syndrome
Recognizing HELLP syndrome is challenging precisely because its symptoms overlap with a number of other conditions. Pain in the right hypochondrium or epigastrium can resemble a gallbladder attack, reflux, or simple digestive problems. Fatigue and nausea are so common in pregnancy that women often dismiss them. And yet these seemingly innocent signals can be the first warning signs.
Let us consider a specific situation: a thirty-year-old woman in her 34th week of pregnancy comes to her doctor feeling "somehow off" – she has a headache, nausea, and feels pressure below her right rib cage. A doctor could easily attribute these symptoms to stress or overwork. However, blood tests reveal alarming values: breakdown of red blood cells, significantly elevated liver enzymes, and a dangerously low platelet count. The diagnosis is clear – HELLP syndrome. Thanks to early detection, the situation can be managed with a controlled delivery and both mother and child are safe. But it does not always turn out this way.
The diagnosis of HELLP syndrome is established exclusively on the basis of laboratory blood tests. Clinical symptoms can point doctors in the right direction, but the diagnosis cannot be confirmed without blood tests. Doctors monitor primarily three indicators: the presence of hemolysis (breakdown of red blood cells manifests, among other things, in elevated bilirubin and lactate dehydrogenase levels), liver enzyme values – particularly ALT and AST – and platelet count. According to the so-called Mississippi classification, HELLP syndrome is divided into three classes based on the severity of platelet decline, with class I being the most severe.
In addition to blood tests, blood pressure is also monitored, because HELLP syndrome is very often accompanied by preeclampsia, i.e., high blood pressure in pregnancy associated with protein in the urine. However, approximately 15–20% of HELLP syndrome cases occur without the presence of preeclampsia, which further complicates early diagnosis. Therefore, women should not wait for the "classic" symptoms of high blood pressure – the absence of these symptoms does not rule out HELLP syndrome.
What should one watch for and when should medical help be sought without delay? Doctors recommend immediately contacting a healthcare facility when the following symptoms occur:
- Sudden or severe pain in the upper abdomen, especially below the right rib cage
- Persistent nausea or vomiting in the third trimester
- Severe headache that does not respond to common medications
- Visual disturbances – blurred vision, light sensitivity, flashing spots
- Sudden swelling of the face, hands, or feet
- General malaise and unusual fatigue that is worsening
None of these symptoms should be ignored. Even if it ultimately turns out to be a benign condition, an examination at a maternity hospital is always a better choice than waiting at home.
The treatment of HELLP syndrome is essentially one – delivery. Once the diagnosis is confirmed, doctors typically proceed to terminate the pregnancy, either naturally, or by caesarean section, depending on the condition of the mother and child and the gestational age of the fetus. If the pregnancy is too early and the mother's condition allows it, doctors may administer corticosteroids to accelerate fetal lung maturation and attempt to extend the pregnancy by a few days. However, each case is individual and the decision depends on the overall clinical picture.
During hospitalization, the patient is given medication to lower blood pressure, blood transfusions or platelets if necessary, and the condition of the liver and kidneys is carefully monitored. The risk of serious complications – such as liver rupture, kidney failure, pulmonary edema, or disseminated intravascular coagulation – is real, and therefore care at a specialized facility is essential.
How to prepare for the risk of HELLP syndrome
Prevention of HELLP syndrome in the true sense of the word does not exist – it cannot be reliably prevented. However, there are steps that can reduce the risk or contribute to early detection. Regular prenatal check-ups are an absolute foundation. It is during these that blood pressure values, urine for the presence of protein, and the overall condition of the mother are monitored. Women with risk factors should be monitored even more carefully and should promptly inform their gynecologist of any deviations.
Expert studies, such as those published in the American Journal of Obstetrics and Gynecology, show that low doses of acetylsalicylic acid (aspirin) administered from the first trimester can reduce the likelihood of developing preeclampsia and its complications, including HELLP syndrome, in at-risk women. This option should be discussed with a doctor individually – not every woman is a suitable candidate for this prophylactic treatment.
Overall lifestyle also plays an equally important role. A healthy, balanced diet rich in vegetables, fruits, whole grains, and quality proteins supports the proper functioning of blood vessels and the immune system. Adequate intake of magnesium, vitamin D, and omega-3 fatty acids is associated with a lower risk of inflammatory processes in the body. This of course does not mean that a proper diet will completely prevent HELLP syndrome, but supporting the overall health of the organism is always worthwhile.
Women who have already experienced HELLP syndrome once should know that the risk of recurrence in a subsequent pregnancy is higher – estimated at approximately 3–27% depending on various factors. Therefore, when planning another pregnancy, consultation with a perinatologist or specialist in high-risk pregnancy before conception is absolutely essential. Early establishment of monitoring and any preventive measures can significantly influence the course and outcome of the pregnancy.
Pregnancy should be a joyful journey toward new life, and although complications such as HELLP syndrome exist, knowledge of their symptoms and trust in one's own body are the best things any expectant mother can do for herself and her child. Listening to the signals of one's own body, not underestimating unusual symptoms, and maintaining open communication with one's doctor – these are steps that can truly save a life in a critical moment.
