tremor in pregnancy
Informed by recognized medical guidance
Overview
A tremor is an involuntary, rhythmic shaking movement. Some women experience mild trembling, usually in the hands, during pregnancy. This is often due to hormonal changes, tiredness, stress, or low blood sugar. In most cases, it is not harmful and may come and go throughout pregnancy.
Key facts
- Tremors during pregnancy are usually temporary and often fade after delivery.
- They can affect the hands, fingers, arms, or less often the legs or head.
- Many cases are triggered by everyday factors like fatigue, stress, or low blood sugar.
- Sometimes a tremor can signal an underlying condition that needs medical attention, so it is always wise to mention it to your healthcare provider.
Mild tremors or shaking are fairly common during pregnancy, especially in the later months. Severe or constant tremors are less common and should be evaluated.
Pregnant women at any age can experience tremors. They may be more noticeable in women who are very tired, stressed, or prone to shaking before pregnancy.
Symptoms
- A tremor accompanied by a severe headache, blurred vision, or confusion
- Shaking with seizure or loss of consciousness
- A tremor combined with sudden swelling of the face or hands (this can be a sign of pre-eclampsia or eclampsia)
- ⚠A tremor that is very severe and makes it hard to hold objects or walk
- ⚠Tremor along with weakness or numbness in the face, arms, or legs
- ⚠Tremor that starts suddenly and is associated with chest pain or difficulty breathing
Common symptoms
- Mild shaking in the hands or fingers
- Trembling when holding a cup or pen

Causes
Main causes
- Hormonal changes during pregnancy
- Increased sensitivity of the nervous system
- Fatigue and lack of sleep
- Stress or anxiety
- Low blood sugar (hypoglycemia)
- Overactive thyroid (hyperthyroidism) in some cases
- Existing tremor disorders that may worsen during pregnancy
Risk factors
- Having a history of tremors before pregnancy
- Experiencing high levels of stress or anxiety
- Frequent tiredness or poor sleep
- Not eating regularly or skipping meals
- Being pregnant with more than one baby
When to see a doctor
See a doctor urgently if:
- Call your midwife or doctor the same day if you have a tremor along with a severe headache, vision problems, or sudden swelling of your hands, feet, or face.
- Seek urgent care if the tremor is so intense that you cannot hold a glass or feed yourself, or if you feel unusually weak on one side of your body.
Book a routine appointment if:
- Mention any tremor at your next prenatal appointment, even if it feels mild.
- Make an appointment if the tremor is new, getting worse, or worrying you.
Diagnosis
Your healthcare provider will ask about your symptoms, how long they last, and any other health problems. They may also perform a physical exam to see how and when the tremor happens.
Tests that may be done
- Blood tests to check blood sugar, thyroid function, and electrolyte levels
- A review of any medicines you are taking
- In rare cases, imaging like an MRI or CT scan may be recommended (though this is uncommon during pregnancy)
What to expect at your appointment
The doctor will likely reassure you that most tremors are not dangerous. If they suspect an underlying condition, they may order tests. Your healthcare provider will work with you to manage the tremor safely while protecting you and your baby.
Treatment
Treatment for tremor in pregnancy depends on the cause. In many cases, no treatment is needed other than rest and simple lifestyle adjustments. If an underlying condition is found, it will be treated carefully and safely during pregnancy.
Self-care at home
- Try to get extra rest and sleep when possible.
- Eat regular meals and snacks to keep blood sugar steady.
- Reduce caffeine intake, such as coffee, tea, and soda.
- Practice relaxation techniques like deep breathing or gentle stretching.
- Ask for help with tasks that require a steady hand if the tremor bothers you.
Medical treatments
Medicines are rarely used for tremors during pregnancy because many drugs can affect the baby. If your tremor is due to a condition like an overactive thyroid, your doctor will talk with you about safe treatment options. Never take any medicine, including herbal products, without speaking to your healthcare provider first.
When is surgery considered?
Surgery is not used to treat tremors during pregnancy. In very rare cases of severe, pre-existing tremor disorders, a specialist may discuss options after delivery.
Living with this condition
Living with a tremor during pregnancy can feel frustrating, but simple adjustments can help. Try to keep a stable routine, rest when tired, and use utensils with larger handles if your hands shake.
Lifestyle tips
- Prioritize sleep and rest.
- Avoid caffeine and sugary drinks that can cause energy swings.
- Try gentle exercise like prenatal yoga or walking, which may reduce stress.
- Use a notebook or phone to track when tremors happen, so you can share details with your healthcare provider.
Diet and exercise
Eat small, frequent meals that include protein and complex carbohydrates to keep blood sugar stable. Light exercise, with your doctor’s approval, can improve circulation and reduce stress. Always check with your midwife or doctor before starting a new exercise routine during pregnancy.
Mental health and emotional wellbeing
It is normal to feel anxious if you notice trembling during pregnancy. Worrying can make shaking worse, so it can help to talk openly about your feelings. If stress or worry becomes overwhelming, speak to your healthcare provider. For urgent mental health support, contact your local crisis service or emergency number.
Prevention
Not all tremors can be prevented, especially those caused by hormonal changes. However, you can reduce the chance of tremor from low blood sugar, stress, or fatigue by eating regularly, resting, and practicing relaxation.
Vaccines
Vaccines are not relevant to preventing tremor during pregnancy. It is important to follow your healthcare provider’s advice about vaccinations for your general health.
Screening programmes
There is no specific screening test for tremor during pregnancy. Regular prenatal checkups are important because your healthcare provider can detect conditions, like thyroid problems or high blood pressure, that may cause tremor.
Complications
If left untreated
- Most tremors do not cause serious problems if left untreated, especially when caused by normal pregnancy changes.
- If a tremor is a sign of pre-eclampsia or eclampsia and is not treated, it can lead to serious complications for both mother and baby.
- Untreated thyroid disease during pregnancy could affect the baby’s development.
Long-term outlook
For the vast majority of women, tremors during pregnancy are temporary and not dangerous. Your body goes through many changes, and shaking can simply be part of that process. With the right support and care, most tremors settle down either before or shortly after the baby is born, and you can look forward to a healthy pregnancy and delivery.
