Snoring lifestyle in pregnancy

Overview

Snoring during pregnancy is common. It happens when air cannot move freely through your nose and throat while you sleep, causing the tissues to vibrate and make a sound. For many women, it is harmless and related to pregnancy changes. But sometimes it can be a sign of a condition called sleep apnea (when breathing stops and starts during sleep), which may need medical attention.

Yes, snoring is very common during pregnancy. Up to 30-40% of pregnant women snore, compared to about 10-20% of non-pregnant women.

Snoring can affect any pregnant woman, but it is more common in women who are overweight, have a large neck circumference, or have a family history of snoring or sleep apnea. It often starts or gets worse in the second and third trimesters.

Symptoms

Common symptoms

• Loud snoring
• Waking up gasping or choking
• Excessive daytime sleepiness
• Morning headaches
• Dry mouth or sore throat on waking

Symptoms in children

• Not applicable for this topic.

Symptoms in older adults

• Snoring is common in older adults due to muscle weakening, but in pregnancy it is related to hormonal and physical changes.

Causes

Main causes

• Hormonal changes that cause swelling in the nasal passages
• Weight gain during pregnancy, especially around the neck
• The growing uterus pushing up against the diaphragm, reducing lung capacity
• Increased blood volume and changes in blood vessels

Risk factors

• Being overweight or obese before pregnancy
• Having a large neck circumference (over 16 inches or 40 cm)
• Having a family history of snoring or sleep apnea
• Smoking
• Having allergies or nasal congestion

When to see a doctor

See a doctor urgently if:

• If you have severe shortness of breath or chest pain (call emergency services immediately)
• If you experience sudden swelling, severe headache, or vision changes (call emergency services immediately)
• If your partner notices you stop breathing during sleep and you wake up gasping

Book a routine appointment if:

• If your snoring is loud and happens most nights
• If you feel very tired during the day despite getting enough sleep
• If you have morning headaches or a dry mouth
• If you have questions about snoring and want to discuss healthy sleep habits

Diagnosis

Your healthcare provider will ask about your snoring, sleep habits, and daytime symptoms. They may also check your blood pressure and weight. If they suspect sleep apnea, they may refer you for a sleep study (polysomnography), which monitors your breathing, heart rate, and oxygen levels during sleep.

Tests that may be done

• Sleep study (polysomnography) – this can be done at a sleep clinic or with a home device
• Blood pressure monitoring
• Oxygen level monitoring (pulse oximetry) during sleep

What to expect at your appointment

If a sleep study is recommended, it is safe during pregnancy. You will sleep with some sensors on your body. The test is painless and helps confirm if you have sleep apnea. Your provider will then discuss treatment options that are safe for you and your baby.

Treatment

Treatment for snoring during pregnancy focuses on relieving symptoms and ensuring you and your baby get enough oxygen. If snoring is simple (no sleep apnea), lifestyle changes often help. If sleep apnea is diagnosed, additional treatments may be recommended.

Self-care at home

• Sleep on your side, not on your back
• Use a pregnancy pillow to support your belly and keep you on your side
• Elevate your head with an extra pillow
• Avoid alcohol and sedatives before bed
• Maintain a healthy weight gain during pregnancy as advised by your provider
• Use a humidifier or saline nasal spray to keep nasal passages moist
• Avoid smoking and secondhand smoke

Medical treatments

For sleep apnea during pregnancy, doctors may recommend a continuous positive airway pressure (CPAP) machine. This device delivers gentle air pressure through a mask to keep your airway open during sleep. It is considered safe in pregnancy. Your provider will adjust the settings for you. In some cases, an oral appliance (a mouthguard-like device) may be considered. Always consult your healthcare provider before starting any treatment.

When is surgery considered?

Surgery is rarely needed for snoring during pregnancy. It is usually not recommended because pregnancy is temporary and snoring often resolves after delivery. If there is a structural problem that persists after pregnancy, surgery may be discussed later.

Living with this condition

Snoring can be disruptive to your sleep and your partner's. But with simple changes, you can often reduce it. Focus on sleeping on your side, especially the left side, which improves blood flow to the baby. Keep your bedroom cool and quiet. If you are diagnosed with sleep apnea, using a CPAP machine may feel strange at first, but it can greatly improve your energy and health.

Lifestyle tips

• Sleep on your side
• Use a pregnancy pillow
• Elevate your head
• Avoid heavy meals close to bedtime
• Practice relaxation techniques before bed, like deep breathing
• Stay active with pregnancy-safe exercise

Diet and exercise

A balanced diet with plenty of fruits and vegetables can help you manage weight gain and reduce nasal congestion. Regular, gentle exercise like walking or prenatal yoga can improve your overall sleep quality and reduce snoring. Always check with your provider before starting a new exercise routine.

Mental health and emotional wellbeing

Snoring can cause worry, especially if you are concerned about your baby's health. Daytime sleepiness can affect your mood and energy. It is important to talk to your provider if you feel anxious or stressed. Remember that most snoring in pregnancy is harmless and improves after birth.

Prevention

You cannot always prevent snoring because pregnancy hormones and weight gain are natural. However, you can reduce your risk by maintaining a healthy weight before and during pregnancy, sleeping on your side from early pregnancy, avoiding smoking, and managing allergies or nasal congestion.

Complications

If left untreated

• If snoring is due to sleep apnea and left untreated, it can increase the risk of high blood pressure, preeclampsia, and gestational diabetes.
• It may also lead to poor sleep for the mother, which can cause daytime fatigue and affect daily functioning.
• In rare cases, severe sleep apnea can affect fetal growth due to low oxygen levels.

Long-term outlook

For most pregnant women, snoring is a temporary issue that improves or goes away after giving birth. Even if you are diagnosed with sleep apnea, treatment with CPAP or lifestyle changes is very effective and safe for you and your baby. With the right support, you can manage snoring and enjoy a healthy pregnancy.
