New or louder snoring during pregnancy: when to bring it up

Snoring that starts or becomes noticeably louder during pregnancy is worth mentioning to your care team rather than dismissing as a normal inconvenience. Sleep-disordered breathing is among the more common sleep problems reported during pregnancy ¹, and sharing what you have observed gives your doctor or midwife the information they need to decide whether further assessment is appropriate.

Describe what has changed

The most useful thing you can do before an appointment is write down exactly what is different. Vague descriptions like "I snore more" are harder for a care team to act on than specific, time-stamped observations.

When you prepare, try to answer these questions:

• When did the snoring start or noticeably change, relative to your stage of pregnancy?
• How often does it happen—every night, most nights, or only occasionally?
• Does it wake you, and if so, what does waking feel like—gasping, heart racing, or simply stirring?
• Does changing your position (rolling onto your side rather than staying on your back) reduce the sound or stop it?
• Has it been getting progressively louder or more frequent over several weeks?

Keeping a brief sleep diary to bring to your appointment turns scattered recollections into a record your care team can actually use. Even three or four nights of notes is more useful than a general impression.

The physical reasons snoring often changes in pregnancy are well established. Hormonal changes cause congestion and swelling of the airway tissues, narrowing the passage air moves through ¹. As the uterus grows, lying on your back becomes more likely to affect circulation and breathing, which is one reason side sleeping is generally recommended from the second and third trimesters onward ⁴. Changes in body weight, particularly around the neck and upper airway, can add further narrowing.

Because several of these changes happen gradually, you or your partner may not notice the shift until it has already become significant. That is why noting a rough starting point—even approximately—helps your care team understand the trajectory.

Include observations from someone who hears you sleep

Because you are asleep when the symptom occurs, a partner or housemate who shares a room is often better placed to observe the details that matter most to a clinical assessment. Ask them to note facts, not interpretations.

Here is a checklist they can work through over a few nights:

• [ ] How loud is the snoring compared to before pregnancy, or compared to a few weeks ago?
• [ ] Is it continuous through the night, or does it stop and start?
• [ ] Have they noticed any pauses in your breathing—moments when you appear to stop breathing altogether—followed by a gasp, snort, or sudden movement?
• [ ] Does rolling you onto your side reduce or stop the sound?
• [ ] How many times per night does a loud snore or breathing change wake them?
• [ ] Has the pattern changed noticeably over the past few weeks?

Pauses in breathing followed by gasping are a specific observation your care team will want to know about ¹. That detail, combined with how often it occurs, helps distinguish louder-than-usual snoring from a pattern that may warrant a referral for further investigation. Encourage your partner to write observations down the morning after rather than relying on memory at the end of the week.

Mention daytime symptoms and breathing concerns

Snoring alone tells only part of the story. The daytime symptoms you experience alongside it help your care team assess whether your sleep is being disrupted enough to affect your health and the health of your pregnancy.

Bring up any of the following at your appointment:

Fatigue and daytime sleepiness are common during pregnancy for many reasons, but when they occur alongside new or worsening nighttime snoring, they become relevant to describe together rather than separately ¹. Framing them as a cluster—"I have noticed these things happening at the same time"—is more informative than listing them as unrelated complaints.

If you also have a stuffy nose that seems to be making things worse at night, that is worth raising at the same appointment. Nasal congestion during pregnancy is common and may be contributing to both the snoring and the disrupted sleep. The guide on a stuffy nose at night during pregnancy covers comfort approaches and questions worth asking.

Ask whether further assessment is needed

You do not need to arrive at an appointment with a self-diagnosis. Your role is to describe what you have observed as specifically as possible, then ask your care team directly whether it warrants further investigation.

If they do want to look further, they may refer you for a sleep study. A sleep study during pregnancy is possible and measures breathing patterns, oxygen levels, and sleep stages overnight ¹. Going in with prepared questions makes that process less stressful and more productive. The guide on having a sleep study during pregnancy has practical questions to ask beforehand.

At the appointment itself, you might ask:

• Is this level of snoring within the range you would expect at this stage of pregnancy, or does it concern you?
• Are there any additional symptoms that, if I develop them before my next appointment, should prompt me to call sooner?
• Does my current sleeping position reduce or increase the risk of breathing disruption?
• If a sleep study is recommended, how will the results be followed up through the rest of my pregnancy?

Writing these questions down before you go means you are less likely to leave the appointment without asking them, particularly if the conversation moves quickly.

Understand why a pillow is not a treatment for sleep apnea

Side sleeping is broadly recommended from the second and third trimesters ⁴, and there is good reason for it: sleeping on your back can compress a major blood vessel, potentially reducing blood flow ⁴. Side sleeping may also reduce snoring because keeping off your back can help maintain a more open airway ²³. ACOG notes that a full-length body pillow can support side sleeping during pregnancy ⁴, and that keeping one or both knees bent, along with a pillow placed between them, can add further comfort.

The Cove Pregnancy Pillow is designed for side sleepers, with a full-length crescent shape that supports the bump and can help keep a knee comfortably bent. Its shredded gel memory foam fill is adjustable through an inner zip, which lets you change the firmness as your body changes through pregnancy. If you want something smaller for the couch or travel, the Cove Pregnancy Pillow Mini uses the same fill and cover approach in a more compact form.

However, a pillow is a comfort aid—nothing more. It supports positioning and reduces physical discomfort during the night. It does not prevent or treat obstructive sleep apnea. When you sleep on your side, your airway may stay more open, which can reduce snoring for some people ²³, but that is a positional effect, not a medical one. If your care team identifies sleep-disordered breathing, treatment will come from clinical assessment and, where indicated, medical intervention.

The distinction matters. Positioning support and clinical treatment are different things, and treating a pillow as a substitute for a clinical conversation can delay an assessment your care team genuinely needs to have. Use the pillow for comfort; use the appointment for the clinical question.
