HELLP syndrome is a rare but serious condition that can happen when you’re pregnant or right after you have your baby. HELLP stands for the different things that happen when you have it:

Hemolysis: This is the breakdown of red blood cells, which carry oxygen from your lungs to your body.

Elevated liver enzymes: When liver enzyme levels are high, it could mean there’s a problem with your liver.

Low platelet count: Platelets help your blood clot.

HELLP syndrome causes problems with your blood, liver, and blood pressure. If left untreated, these issues can hurt you and your baby.

Major complications tied to HELLP syndrome include:

  • Seizures
  • Stroke
  • Liver failure
  • Liver injury or bleeding
  • Kidney injury or failure
  • Eclampsia or seizures during pregnancy
  • C-section
  • Infection
  • Sepsis
  • Retinal detachment, where your retina pulls away from its place at the back of your eyes
  • Bleeding
  • Death

How does HELLP syndrome affect the baby?

HELLP syndrome can cause placental abruption, which means the separation of the placenta from the wall of the uterus before the baby is born. Placental abruption can cause bleeding, affect your baby’s growth, and lead to premature birth or stillbirth.

HELLP syndrome can also lead to placental failure, where the placenta is unable to supply oxygen and nutrients to your baby.

Other health problems HELLP syndrome can cause for your baby include:

  • Intrauterine growth restriction (IUGR), where your baby doesn’t grow as well as they should
  • Blood disorders such as anemia and low platelet count at birth
  • Respiratory distress syndrome, a breathing problem because the lungs are not fully developed or working
  • Low birth weight
  • Extreme preterm birth, when your baby is born at or before 28 weeks of pregnancy
  • Death

There may be a link between HELLP syndrome and preeclampsia and eclampsia. Preeclampsia is when a pregnant person has high blood pressure and damage to other organs such as their liver and kidneys. It usually starts after 20 weeks of pregnancy. Eclampsia is a more severe form of preeclampsia that includes seizures.

Some experts believe that HELLP syndrome is a severe type of preeclampsia, while others think HELLP might actually be a different disorder. Most people with HELLP have high blood pressure and protein in their urine, similar to preeclampsia. But about 15%-20% don’t have these symptoms. 

Either way, HELLP syndrome belongs to a group of conditions called hypertensive complications of pregnancy, along with preeclampsia, gestational hypertension, and eclampsia.

Doctors don’t know what causes HELLP syndrome. Your chance of it is higher if you’ve had it before. Most people who get it have high blood pressure first. But you can get HELLP with normal blood pressure.

Experts think your odds may be higher if you:

  • Are older than 25
  • Are white
  • Have given birth two or more times before

HELLP syndrome symptoms often come on quickly. They include:

If you have symptoms of HELLP syndrome, talk to your doctor. They’ll do a physical exam and tests to check for:

The main solution for HELLP syndrome is to give birth as soon as possible. This means your baby may have to be born early. The risks are too serious for you and your baby if you stay pregnant with HELLP syndrome.

Treatment may also include:

  • Corticosteroid medicines to help your baby’s lungs develop more quickly
  • Medicines for high blood pressure
  • Meds to prevent seizures
  • Blood transfusion

There’s no way to prevent HELLP syndrome. The best thing you can do is keep yourself healthy before and during pregnancy and watch for early signs of the condition. The following steps can help:

  • See your doctor regularly for prenatal visits.
  • Tell your doctor if you’ve had any high-risk pregnancies or if someone in your family has had HELLP syndrome, preeclampsia, or other blood pressure problems.
  • Know the symptoms and call your doctor ASAP if you have them.

When you have HELLP syndrome, giving you anesthesia for your C-section can be a difficult decision for your doctor to make because symptoms such as low platelet count, bleeding, and high blood pressure could cause you more health problems. Doctors also don’t have clear guidelines on what anesthesia to use or the best way to manage this situation.

A case report of a 35-year-old, 25-week pregnant person with HELLP syndrome found that using spinal anesthesia (where the drug is injected into the lower back that you may be awake with) comes with a lower risk of bleeding in the brain compared with general anesthesia (which make you completely asleep).

Another case report involving a 28-year-old, 34-week pregnant person with HELLP and other health problems suggests that spinal anesthesia can be considered if you have HELLP, normal blood clotting, and a corrected platelet count.

Your doctor will weigh the risks and benefits of different anesthetic methods and determine which is best for your case.

HELLP syndrome gets better after delivery. But your doctor still has to keep monitoring you because you might have bleeding and need to get emergency blood transfusions.

Although this condition is relatively rare, if you’ve had HELLP, you’ll likely have it again in your next pregnancy. You might also have high blood pressure and heart diseases later in life.

Having HELLP syndrome is a sudden and overwhelming change to your pregnancy reality. Getting medical help and receiving urgent treatment may also cause mental and emotional distress. The overwhelming feelings may continue even after you’ve gotten treatment for your symptoms and you and your baby are safe and fine.

Having a strong support system that includes your loved ones, your doctor, and other people who have had HELLP syndrome or other serious pregnancy complications can help with your mental and emotional recovery. 

  • Ask your loved ones for help with daily errands and chores as needed so you can take more time to recover. 
  • Follow your doctor’s recommendations for treatment, rest, and recovery. If you have any questions or concerns about your medicines, contact them as soon as you can.
  • Consider joining online or in-person support groups to connect with and learn from other families who have had similar experiences. This can help with any feelings of loneliness or isolation you may be experiencing. You can find support groups and places to share your story, as well as learn from others, on the Preeclampsia FoundationMomma's Voices, and Preeclampsia, Eclampsia & HELLP Syndrome Survivors Global Support Network.
  • Be gentle with yourself. You might feel grief, guilt, and other emotions that are hard to understand or explain. This is normal, and showing kindness can make your mental and emotional recovery smoother. Journaling or getting involved in a creative hobby can help with self-expression and releasing unpleasant emotions.
  • Speak with a therapist. Consider working with a therapist who specializes in pregnancy complications and postpartum care. They can help you process your feelings and manage your emotions.

HELLP syndrome is a rare pregnancy complication that often happens during the third trimester. But it can also occur during labor and delivery or after delivery. No one knows how to prevent it yet, but get immediate medical help if you have symptoms such as extreme tiredness, blurred vision, weight gain, headache, nausea, and vomiting. This condition can be treated and goes away after delivery for most people. It can happen to you again in another pregnancy, so talk to your doctor about the best ways to reduce your chances of having it again.

What are the criteria for HELLP?

The criteria for HELLP include: 

  • Hemolysis or breakdown of red blood cells
  • Elevated liver enzymes
  • Low platelet count

What is the difference between DIC and HELLP syndrome?

Disseminated intravascular coagulation (DIC) is a rare blood clotting disorder that often happens as a complication of other serious health problems such as HELLP syndrome. It causes organ damage and bleeding, complicating emergency surgeries in people with HELLP syndrome.

DIC symptoms include uncontrollable bleeding from different body parts, bruising, fever, difficulty breathing, confusion, and memory loss. HELLP syndrome also involves prolonged bleeding but is marked by additional symptoms such as fatigue, sudden weight gain, and swelling.

Does HELLP syndrome go away?

Yes, HELLP syndrome often goes away within three days after giving birth.
