HELLP syndrome is a group of symptoms that can develop in pregnant women. It includes:
- EL: elevated liver enzymes
- LP: a low platelet count
Hemolysis refers to a breakdown of red blood cells. In people with hemolysis, the red blood cells get broken down too soon. This may result in low red blood cell levels and can eventually lead to anemia, a condition in which the blood doesn’t carry enough oxygen to the rest of your body.
Elevated liver enzymes indicate that your liver isn’t functioning properly. Inflamed or injured liver cells leak high amounts of certain chemicals, including enzymes, into your blood.
Platelets help with blood clotting. When platelet levels are low, you’re at risk for excessive and bleeding.
HELLP syndrome affects less than 1 percent of all pregnancies. However, it is a major health concern because it can be life-threatening to both the mother and the unborn baby. Prompt treatment and delivery of the baby are generally required for the best outcome.
HELLP syndrome usually develops in the last trimester of pregnancy, before the 37th week. However, the cause of symptoms is unknown. Some experts believe HELLP syndrome is related to preeclampsia, a pregnancy complication that causes high blood pressure. There are also certain factors that can increase your risk of developing HELLP syndrome.
HELLP syndrome symptoms are very similar to those of the flu. They may also seem to be “normal” side effects of pregnancy. However, it’s important see your doctor right away if you’re experiencing any flu-like symptoms during pregnancy. Only your doctor can ensure that your symptoms aren’t indicative of serious health issues.
The symptoms of HELLP syndrome may vary from person-to-person, but the most common ones include:
- feeling generally unwell or fatigued
- stomach pain
You may also experience:
- swelling, especially in the hands or face
- excessive and sudden weight gain
- blurry vision or changes in vision
- heartburn or indigestion
- shoulder pain
- pain when breathing deeply
In rare cases, you may also have excessive nosebleeds and seizures.
The cause of HELLP syndrome is unknown, but there are certain factors that may increase your risk of developing it.
Preeclampsia is the greatest risk factor. This condition is marked by high blood pressure and swelling, and it typically occurs during the last trimester of pregnancy. However, not all pregnant women with preeclampsia will develop HELLP syndrome.
Other risk factors include:
- being over age 30
- being Caucasian
- being very overweight
- having previous pregnancies
- having a poor diet
- having diabetes
You’re also at a higher risk for HELLP syndrome if you had the condition during a previous pregnancy. In fact, your risk can increase by 19 to 27 percent in each future pregnancy.
Your doctor will perform a physical exam and order various tests if HELLP syndrome is suspected. During the exam, your doctor may feel for abdominal tenderness, an enlarged liver, and any excess swelling. These can be signs of a liver problem. Your doctor may check your blood pressure as well.
Certain tests can also help your doctor make a diagnosis. Your doctor may order a:
- blood test to evaluate platelet levels and red blood cell count
- urine test to check for elevated liver enzymes and abnormal proteins
- CT scan to determine whether there’s bleeding in the liver
Once a HELLP syndrome diagnosis is confirmed, delivery of the baby is the best way to prevent complications. In many cases, the baby is born prematurely.
However, your treatment may vary depending on the severity of your symptoms and how close you are to your due date. If your HELLP syndrome symptoms are mild or if your baby is less than 34 weeks old, your doctor may recommend:
- bedrest, either at home or in the hospital
- blood transfusions to treat anemia and low platelet levels
- magnesium sulfate to prevent seizures
- antihypertensive medication to control blood pressure
- corticosteroid medication to help your baby’s lungs mature in case an early delivery is needed
During treatment, your doctor will monitor your red blood cell, platelet, and liver enzyme levels. Your baby’s health will also be watched closely. Your doctor may recommend certain prenatal tests that evaluate movement, heart rate, stress, and blood flow.
You may be given medications to help induce labor if your doctor determines that your condition requires immediate delivery of your baby. In some cases, a cesarean delivery may be performed. However, this can cause complications if you have blood-clotting issues related to low platelet levels.
Most women with HELLP syndrome will recover completely if the condition is treated early. Symptoms also improve significantly after the baby is delivered. In fact, most symptoms and side effects will go away within two to three days after delivery.
Perhaps the biggest concern is the impact HELLP syndrome can have on the baby. Most babies are delivered early when the mothers develop HELLP syndrome, so there’s often a greater risk of complications from premature delivery. Babies who are born before 37 weeks are carefully monitored in the hospital before they are able to go home.
Complications associated with HELLP syndrome include:
- blood clots
- liver rupture
- kidney failure
- acute respiratory failure
- fluid in the lungs
- excessive bleeding during delivery
- placental abruption, which occurs when the placenta detaches from the uterus before the baby is born
Early treatment is the key to preventing these complications. However, some complications may occur during treatment. Symptoms of HELLP syndrome can also affect you and your baby after delivery.
HELLP syndrome isn’t preventable in most pregnant women because the cause of the condition isn’t known. However, people with preeclampsia can lower their risk for HELLP syndrome by maintaining a healthy lifestyle. This includes exercising regularly and eating a heart-healthy diet that consists of whole grains, vegetables, fruit, and lean protein. It’s also important to contact your doctor immediately if you’re experiencing symptoms of HELLP syndrome. Early detection and treatment can help lower the risk of complications.
