What Are Maternal Symptoms of Placental Insufficiency?

Placental insufficiency often has no symptoms the mother can feel. Because you cannot physically feel your placenta working, there is no specific pain, cramp, or sensation that directly signals the placenta is struggling. Instead, placental insufficiency is a condition usually detected by your medical team through ultrasounds that measure your baby’s growth—particularly their abdominal circumference (their belly measurement)—and evaluate blood flow ^{[1] [2]}. Because the condition is often silent, a mother can feel completely normal even when placental dysfunction is occurring.

While there is no reliable symptom that directly measures placental function, there are two important ways you might notice that something is wrong: changes in your baby’s movements, and symptoms of the underlying conditions that can cause placental issues.

The Most Important Warning Sign: Decreased Fetal Movement

Reduced fetal movement is an important warning sign of possible fetal compromise, including issues associated with placental insufficiency ^[3]. Any clear reduction or change from your baby’s usual movement pattern requires prompt medical attention ^[4].

If your baby is moving less than usual:

• Contact your maternity unit or obstetric team immediately. Do not wait until the next day or your next scheduled appointment ^[4].
• Do not use a home fetal Doppler or try home remedies (like drinking something sugary) as a substitute for a professional medical assessment.
• What to expect: A standardized medical assessment after decreased movement typically includes monitoring the baby’s heart rate. Depending on how far along you are, it may also include an ultrasound to check the baby’s growth, amniotic fluid levels, and blood flow through the umbilical cord ^[4].

Note: Decreased movement does not diagnose placental insufficiency—it can have other causes—but normal movement does not rule out placental issues either. It is simply a critical reason to seek immediate evaluation.

Symptoms of Underlying Causes

Although placental issues themselves may not cause maternal symptoms, some conditions associated with them do. Preeclampsia (a serious blood pressure condition) is closely linked to placental dysfunction ^[5].

However, preeclampsia is often symptom-free and may only be found during routine prenatal visits through blood pressure and urine tests. If symptoms do occur, they can include ^[5]:

• Severe or persistent headaches that do not go away with medication
• Vision changes, such as seeing spots, flashing lights, or experiencing blurry or major vision loss
• New, severe, or persistent pain in the upper abdomen (often right under your ribs)
• Sudden, severe swelling in your face or hands (though preeclampsia can occur without any swelling)
• Shortness of breath

When to Seek Emergency Care:
If you experience severe difficulty breathing, severe chest or upper abdominal pain, fainting, a seizure, confusion, major vision loss, or a sudden and severe headache, seek emergency help immediately (call emergency services or go to the nearest emergency room). Do not wait for a return call from your obstetric clinic for these severe symptoms.

The Bottom Line

There is no reliable home test for placental function. It is completely normal to worry about missing a sign of a complication, but the best steps you can take are keeping all prenatal appointments so your doctor can monitor your blood pressure and the baby’s growth ^{[1] [2]}, and immediately reporting any decrease in your baby’s normal movement patterns ^{[3] [4]}.
