Placental Abruption Symptoms

Common Placental Abruption Symptoms

Some common symptoms of placental abruption are as follows:

• Sudden or continuous abdominal pain

• Vaginal bleeding, ranging from light spotting to heavy bleeding

• Tenderness over the uterus

• A firm, tense or rigid abdomen

• Frequent uterine contractions that occur close together

• Lower back pain

• Reduced or absent baby movements

• Dizziness, weakness or faintness

• Feeling the fetus move less

Vaginal bleeding during placental abruption varies and does not actually highlight the severity of abruption. Sometimes women might not feel bleeding as the blood is trapped between the placenta and the uterus.

Placental Abruption Symptoms That Should Not Be Ignored

Active placental separation, maternal blood loss or reduced oxygen delivery to the baby can show up as:

Bleeding in later pregnancy has several possible causes. A maternity team needs to assess the symptoms because placenta praevia, labour and other emergencies can produce overlapping signs.

Why Does Placental Abruption Occur?

While the exact cause of placental abruption is still unknown, it occurs when the blood vessels supplying blood to the placenta tear or are damaged. This can lead to the placenta detaching itself from the inner wall of the uterus before delivery.

This detachment of placenta is usually triggered by hypertension during pregnancy, also called preeclampsia. It weakens or damages the delicate blood vessels at the uterine-placental junction. Placental abruption also occurs due to external physical trauma such as a fall, motor collision or a hit to the abdomen. This exerts a shearing force on the uterus, leading to the abruption.

Other primary causes include rapid uterine decompression (such as a sudden loss of amniotic fluid), vessel constriction from smoking or substance use, short umbilical cords, or compromised attachment sites caused by uterine fibroids or structural abnormalities.

Placental Abruption Symptoms That Require Immediate Medical Attention

Some placental abruption symptoms that require immediate medical attention are as follows:

• Heavy or continuous vaginal bleeding

• Severe abdominal or lower back pain that does not ease

• A hard, painful or board-like abdomen that does not relax between contractions

• Rapid and continuous contractions with little to no rest in between

• Reduced or absent baby movements

• Fainting or difficulty staying conscious

• Confusion or severe weakness

• Pale, cold or clammy skin

• A rapid heartbeat or fast, shallow breathing

• Significant pain or bleeding after abdominal trauma

• Any fall, blow to the uterus, or injury requires immediate medical attention

Placental Abruption Symptoms Based on Type

Placental abruption symptoms vary depending on where the bleeding occurs and how much of the placenta has separated from the uterine wall. The symptoms of placental abruption, based on type, are as follows:

Symptoms of Placental Abruption-Specific Conditions

The following are symptoms of placental abruption specific condition:

Can You Have Placental Abruption Without Symptoms?

Yes, placenta abruption can sometimes occur with a few or no obvious symptoms, particularly when there is only very small, mild or chronic separation that may produce only occasional dark spotting.

However, there is a difference between no symptoms and concealed symptoms. When blood gets trapped between the placenta and the uterine wall, there may be no visible bleeding. Some silent or mild cases of placental abruption only come to attention during assessment for reduced foetal growth, low amniotic fluid or an abnormal foetal heart rate.

When Can Placental Abruption Symptoms Become Life-Threatening?

The greatest danger comes from major blood loss and interruption of placental blood flow. These complications need emergency treatment:

How are Placental Abruption Symptoms Diagnosed?

Obstetricians and the maternity team combine the history, physical findings, blood results and the baby's heart rate to assess your condition. As placental abruption is an emergency, doctors generally do not wait for lab results to start the treatment.

Some diagnostic tests that doctors might recommend for placental abruption include:

The maternity team also considers placenta praevia, labour and other causes of bleeding or abdominal pain. Diagnosis remains primarily clinical.
