HELLP Syndrome and Kidney Health: What Every Woman Should Know
"Understanding the risks of acute kidney injury during HELLP syndrome and how early management can protect your health."
HELLP syndrome (Hemolysis, Elevated Liver enzymes, and Low Platelet count) is a serious complication of pregnancy, typically occurring in the late stages. While many are familiar with pre-eclampsia, HELLP syndrome represents a more severe form that can have life-threatening consequences for both mother and baby. One of the significant risks associated with HELLP syndrome is acute kidney injury (AKI), a sudden decline in kidney function.
The kidneys play a vital role in filtering waste and excess fluids from the blood, maintaining electrolyte balance, and producing hormones. When HELLP syndrome develops, it can severely impact these functions, leading to AKI. Understanding the connection between HELLP syndrome and kidney health is crucial for early detection, timely intervention, and improved outcomes.
This article aims to shed light on the prevalence of AKI in women with HELLP syndrome, explore the risk factors involved, and emphasize the importance of prompt medical management to protect kidney function and overall well-being. By providing clear, accessible information, we hope to empower women and their families to make informed decisions and seek timely care.
How Understanding Has Evolved
A 2003 report described itself as the first to clearly illustrate the probable processes behind acute renal failure in HELLP syndrome. By 2019, researchers noted that renal pathological investigation of HELLP-related acute kidney injury (AKI) had rarely been reported and set out to examine persistent AKI and renal outcomes. A later review described the three decades since HELLP syndrome was first named as a period in which many milestones had been passed toward better understanding the condition.
AKI and HELLP Syndrome: Understanding the Risks
Research indicates a notable prevalence of AKI in women diagnosed with HELLP syndrome. Studies show that approximately 32% of women with HELLP syndrome experience AKI. This highlights the critical need for close monitoring of kidney function in pregnant women with HELLP syndrome.
- Reduced Blood Flow to the Kidneys: HELLP syndrome can cause vasoconstriction and reduced blood flow to the kidneys, impairing their ability to filter waste effectively.
- Endothelial Damage: The syndrome can damage the endothelial cells lining the blood vessels in the kidneys, leading to inflammation and impaired kidney function.
- Microangiopathic Hemolysis: The breakdown of red blood cells (hemolysis) in HELLP syndrome can release substances that damage the kidneys.
- Other Complications: Conditions like disseminated intravascular coagulation (DIC) and severe pre-eclampsia, often associated with HELLP, can further compromise kidney function.
Severe Kidney Outcomes
A 2021 retrospective study set out to identify risk and prognosis factors associated with AKI in patients with HELLP syndrome during pregnancy. Although dialysis-requiring cases are described as relatively uncommon, a 2026 case report concerns a previously healthy 40-year-old primigravida who developed HELLP syndrome and AKI requiring temporary hemodialysis. Acute renal cortical necrosis is another important possibility to consider when renal failure develops in HELLP syndrome, according to a 2012 article.
Perinatal Death Estimates
One review estimates the perinatal death rate associated with AKI in the setting of HELLP syndrome at 26–48.2%. It gives a comparison range of 23.5–38% for AKI without HELLP syndrome. Because the reported ranges overlap, these estimates do not establish a single rate that applies to every pregnancy.
Protecting Your Kidney Health During Pregnancy
The good news is that with early diagnosis and appropriate medical management, the risk of severe kidney damage from HELLP syndrome can be minimized. Treatment typically involves:
Studying Pregnancy-Related AKI
A 2024 article examines pregnancy-related acute kidney injury (PR-AKI) in women with hypertensive disorders of pregnancy, including HELLP syndrome. It reports that these women are affected by AKI during pregnancy at higher rates than women without hypertension. This comparison highlights the value of further research into PR-AKI among women with hypertensive pregnancy disorders.
A Case Without Prenatal Hypertension
A 2025 case report describes HELLP syndrome without prenatal hypertension that rapidly progressed to disseminated intravascular coagulation (DIC) and AKI, despite blood loss of 800 mL. A separate 2023 case report notes that AKI can lead to anuria, heart failure, and severe pulmonary edema. These reports illustrate serious outcomes described in individual cases and should not be read as describing the same patient.

Pregnancy can present challenges, but staying informed and proactive can significantly improve outcomes. If you're at risk of HELLP syndrome or experience any concerning symptoms, don't hesitate to consult your healthcare provider. Early detection and proper management are vital for protecting both your health and your baby's.
