What Causes Bell’S Palsy In Pregnancy

What is Bell’s Palsy?

Bell’s palsy is a type of facial paralysis that is caused by temporary damage to the facial nerve. It occurs when the facial nerve becomes swollen and inflamed, resulting in facial weakness or paralysis. The condition can be very unnerving and could cause significant cosmetic changes.

What Causes Bell’s Palsy In Pregnancy?

Bell’s palsy is not well understood and its exact cause remains unknown. It is believed to be caused by an infection, virus or inflammation that affects the facial nerve. People who are pregnant or have diabetes are particularly susceptible to developing Bell’s palsy.

During Pregnancy

During pregnancy, the body undergoes changes that can have an effect on a woman’s health. The increased fluid in the body may lead to swelling of the facial nerve, which could lead to Bell’s palsy. Additionally, the hormones in the body can affect facial nerve function, leading to facial paralysis.

Risk Factors

Some of the risk factors associated with developing Bell’s palsy during pregnancy include:

  • Being in the third trimester of your pregnancy
  • A weakened immune system
  • A history of diabetes or autoimmune disorders
  • Exposure to certain viruses or infections

Diagnosis and Treatment

If you experience the symptoms of Bell’s palsy during pregnancy, it is important to visit your doctor for a proper diagnosis. Generally, Bell’s palsy resolves itself and does not require treatment. However, in cases where the facial paralysis persists, your doctor may recommend physical therapy, corticosteroid medications, or even surgery.


Bell’s palsy is a type of facial paralysis that is caused by temporary damage to the facial nerve. It can occur during pregnancy due to physiological changes that can cause swelling of the facial nerve, hormones affecting facial nerve function, or a weakened immune system. If you experience symptoms of Bell’s palsy, it is important to seek medical attention for a proper diagnosis and treatment.

What Causes Bell’s Palsy In Pregnancy?

Bell’s palsy is a type of paralysis that affects the facial nerve. It can cause one side of the face to become droopy or appear weak, leading to a wide range of physical and emotional changes. During pregnancy, there may be a variety of factors that can increase a woman’s risk of developing Bell’s palsy.

Risk Factors for Bell’s Palsy in Pregnancy

The development of Bell’s palsy during pregnancy has been correlated with several risk factors:

  • Hormonal Changes: Pregnant women experience significant fluctuations in their hormones, which can contribute to the development of Bell’s palsy.
  • Stress: Pregnancy is a stressful time, and studies have linked this heightened stress to Bell’s palsy symptoms.
  • Weakened Immune System: During pregnancy, the immune system is often weakened, leading to a greater chance of developing Bell’s palsy.
  • Health Conditions: Women who have a history of autoimmune diseases or diabetes during pregnancy are at higher risk for Bell’s palsy development.
  • Infections: Pregnant women are at higher risk for certain infections, such as Lyme disease or the herpes virus, which can contribute to Bell’s palsy development.

Common Symptoms of Bell’s Palsy in Pregnancy

Common symptoms of Bell’s palsy in pregnancy include:

  • Facial droop on one side
  • Difficulty closing the eye on one side
  • Dryness in the eye on the affected side
  • Pain behind the ear or in the jaw
  • Twitching or spasms in the facial muscles
  • Headache
  • Difficulty breathing through the nose

Diagnosing Bell’s Palsy During Pregnancy

If you suspect you may have Bell’s palsy during pregnancy, it is important to seek medical attention as soon as possible. A doctor may diagnose Bell’s palsy using a physical exam and the following tests:

  • MRI: An MRI can detect damage to the facial nerve.
  • CT Scan: A CT scan may also be used to detect facial nerve damage.
  • Blood Tests: A blood test can identify infections that may be contributing to Bell’s palsy.
  • Electromyography: Electromyography measures the responses from the facial muscles in order to diagnose muscle weakness or paralysis.

Treatment for Bell’s Palsy in Pregnancy

Treatment for Bell’s palsy during pregnancy is typically focused on symptom management and preventing further damage. Treatment may include:

  • Medications: Your doctor may prescribe medication to reduce inflammation, prevent infections and reduce pain.
  • Physical therapy: Physical therapy may help reduce facial muscle spasms and improve mobility of the affected side of the face.
  • Eye Care: To prevent discomfort or corneal damage, it is important to practice eye care such as using eye drops and protective eye wear.
  • Corticosteroid Injections: In some cases, your doctor may recommend corticosteroid injections to reduce the inflammation of the facial nerve.

Bell’s palsy can cause many physical and emotional changes, but it is important to remember that in most cases it resolves itself over time. If you are pregnant and experience any of the symptoms of Bell’s palsy, it is important to speak with your doctor for proper diagnosis and treatment.
