Sleep Apnea During Pregnancy: A Silent Risk and Safe Solution
Loud snoring. Waking up gasping. Exhaustion that no amount of rest seems to fix. If you’re pregnant and experiencing these symptoms, this isn’t just pregnancy fatigue. It could be obstructive sleep apnea (OSA), a sleep disorder that carries real risks for both you and your baby.
Recent research shows that between 3 and 27 percent of pregnant women develop sleep apnea, with rates climbing sharply in the third trimester. The good news is that effective, safe treatment is available right here in southern New Hampshire. Dr. Stephen Ura, DDS, MAGD, at the Center for Dental Sleep Health in Nashua, specializes in oral appliance therapy—a CPAP-free solution designed to keep your airway open, protect your oxygen levels, and help you sleep through the night.

What is Sleep Apnea During Pregnancy?
Obstructive sleep apnea (OSA) is a sleep-disordered breathing condition in which the muscles of the upper airway relax and collapse during sleep, cutting off the flow of air. These breathing pauses, called apneic events, can occur dozens or even hundreds of times per night and may last 10 seconds or longer. Each interruption causes a partial arousal, fragments your sleep architecture, and drops your blood oxygen levels.
Pregnancy makes all of this worse. Your body undergoes dramatic physiological changes that narrow the airway, alter respiratory mechanics, and increase the work of breathing—all while you’re trying to grow another human being.
Why does sleep apnea develop during pregnancy? Several compounding factors are at play:
- Airway edema from estrogen: Rising estrogen levels cause swelling of the nasal passages and soft tissue throughout the upper airway, narrowing the space through which air must travel
- Weight gain and neck circumference: Increased fat deposition around the neck and throat compresses the airway from the outside
- Third-trimester diaphragm pressure: As your uterus expands, it pushes upward on the diaphragm, reducing lung capacity and increasing the effort required with each breath
- Fluid retention: Pregnancy-related fluid accumulation in soft tissues further contributes to upper airway narrowing, particularly in the recumbent (lying down) position
- Insulin resistance: Pregnancy hormones affect glucose metabolism, and OSA independently worsens insulin sensitivity—a compounding risk for gestational diabetes
- Higher Mallampati score: Anatomical changes during pregnancy increase the Mallampati classification, a clinical marker of airway obstruction risk
These changes evolve throughout pregnancy. Research confirms that symptoms and daytime sleepiness both increase with advancing gestational age, peaking in the third trimester—the same window when many women are already the most uncomfortable and sleep-deprived.
Signs of Sleep Apnea During Pregnancy: What to Watch For
Many expecting mothers dismiss sleep apnea symptoms as “just pregnancy.” Please don’t. These are the warning signs that deserve attention:
Nighttime symptoms:
- Loud, persistent snoring that wakes your partner
- Gasping or choking sounds during sleep (often reported by a partner, since you’re asleep when they occur)
- Frequent nighttime wakings unrelated to needing the bathroom
- Waking with a sensation of not being able to catch your breath
Daytime symptoms:
- Unrelenting fatigue even after a full night of sleep
- Morning headaches that ease as the day progresses
- Difficulty concentrating or “pregnancy brain” that seems worse than normal
- Excessive daytime sleepiness (a clinical score above 10 on the Epworth Sleepiness Scale is considered significant)
- Mood changes, irritability, or increased anxiety
Who is most at risk?
- Women with a BMI above 25 before pregnancy
- Those over age 30
- Women who snored before pregnancy
- Those with pre-existing hypertension, diabetes, or a history of preeclampsia
- Multiple-gestation pregnancies (twins, triplets)
If any of these sound familiar, the most important next step is an evaluation. A sleep dentist near you in Nashua can connect you with the right screening and put an effective treatment plan in place quickly.
Why Untreated Sleep Apnea During Pregnancy Is Dangerous
Sleep apnea isn’t just uncomfortable. When left untreated during pregnancy, the repeated cycles of oxygen desaturation and sleep fragmentation create a cascade of physiological stress that significantly increases the risk of serious complications.
Risks to You
- Preeclampsia: This is the most well-documented connection. OSA triggers repeated surges in blood pressure during apneic episodes, and over time, this contributes to the sustained hypertension that defines preeclampsia. Population-based studies consistently show significantly elevated rates of preeclampsia in pregnant women with untreated OSA, a condition that can progress rapidly to seizures and requires immediate medical intervention.
- Gestational hypertension: Even short of full preeclampsia, high blood pressure during pregnancy increases the risk of placental abruption, restricted fetal growth, and the need for early delivery.
- Gestational diabetes: OSA worsens insulin resistance independently of weight gain. The combination of pregnancy-related hormonal changes and the metabolic disruption of untreated sleep apnea significantly raises the risk of developing gestational diabetes mellitus (GDM).
- Increased cesarean delivery rate: Studies show that women with OSA have higher rates of C-section, likely linked to fetal monitoring concerns and blood pressure management complications during labor.
- Cardiomyopathy and cardiovascular risk: Women diagnosed with OSA at delivery show elevated rates of cardiomyopathy and congestive heart failure. These risks are compounded in the presence of obesity.
- Mental health: Fragmented, non-restorative sleep has a direct and measurable impact on mood. Pregnant women with OSA experience higher rates of prenatal and postpartum depression and anxiety.
Risks to Your Baby
Every apneic event drops your blood oxygen levels. Your placenta is the only oxygen source your baby has. Repeated oxygen desaturation events place real physiological stress on fetal development:
- Intrauterine growth restriction (IUGR): Reduced oxygen delivery limits fetal growth, sometimes significantly
- Low birth weight and small for gestational age (SGA) infants: A systematic review of the available research found a consistent association between maternal OSA and delivering smaller babies
- Preterm birth: OSA increases the risk of delivering before 37 weeks
- Lower Apgar scores at birth
- Higher NICU admission rates
- Long-term neurological implications: Emerging research suggests that fetal hypoxia from maternal OSA may have developmental consequences that extend beyond birth
The risks are real, but so is the treatment. This is a solvable problem, and solving it now protects both of you.
Sleep Apnea Treatment Options for Pregnant Women
Treatment during pregnancy needs to be safe, effective, and practical. Dr. Ura offers solutions specifically suited to the unique needs of expectant mothers in the Nashua area.
Oral Appliance Therapy (OAT) — Dr. Ura's Primary Recommendation
For most pregnant women with mild to moderate OSA, and for those who cannot tolerate CPAP, custom oral appliance therapy is the treatment of first choice at our Nashua clinic.
A mandibular advancement device (MAD) is a custom-fitted, FDA-cleared oral appliance that gently repositions your lower jaw forward while you sleep. This forward positioning pulls the tongue and soft tissues of the throat away from the back of the airway, keeping it patent (open) throughout the night. The result: fewer apneic events, less oxygen desaturation, and dramatically better sleep quality.
Why oral appliances work especially well during pregnancy:
- No mask, no claustrophobia: A common CPAP complaint during pregnancy is worsened nausea and anxiety from the mask. Oral appliances have no mask at all
- Side-sleeping compatible: Pregnant women are advised to sleep on their left side—oral appliances work in any sleeping position, unlike CPAP machines that can pull and tug
- Completely silent: No air pressure noise to disturb your partner or interrupt your sleep
- Compact and travel-friendly: No equipment, no power cord, no bulky machine to haul to prenatal appointments or hospital pre-registration visits
- No electricity required: Useful during New Hampshire’s occasional power outages
- Drug-free and chemical-free: The device works entirely through mechanics—no medications, no systemic exposure
Each appliance is custom-fabricated from impressions of your teeth, so the fit is precise and comfortable, not one-size-fits-all. Dr. Ura calibrates the jaw position carefully and adjusts it over follow-up visits to maximize efficacy and comfort throughout your pregnancy.
Is oral appliance therapy safe during pregnancy? Yes. It works purely mechanically. Unlike medications, there are no drugs introduced into your system, and the treatment poses no risk to your developing baby.
CPAP Therapy — When It's Necessary
For severe OSA or in cases where oral appliance therapy alone isn’t achieving adequate oxygen saturation, continuous positive airway pressure (CPAP) therapy remains the clinical gold standard. CPAP delivers a steady stream of pressurized air through a mask, physically preventing airway collapse.
We recognize that many pregnant women struggle with CPAP adherence due to morning sickness, nasal congestion, mask discomfort, and a heightened sense of claustrophobia. Our team works closely with sleep medicine physicians in the Nashua area to ensure that when CPAP is clinically indicated, you receive the correct pressure settings, a well-fitted mask, and the ongoing support needed to stay consistent with treatment.
For women with moderate OSA, a hybrid approach—combining a custom oral appliance with positional therapy—is often highly effective and far easier to tolerate than CPAP alone.
Positional Therapy
Research confirms that sleeping in the supine (flat on your back) position significantly worsens OSA by allowing the tongue and soft tissues to fall back into the airway. In pregnancy, supine sleeping is already discouraged after the first trimester due to pressure on the vena cava. For women with positional OSA, simply avoiding back sleeping—using a supportive wedge pillow or body pillow to maintain lateral positioning—can reduce the apnea-hypopnea index (AHI) meaningfully. Dr. Ura discusses positional strategies as part of every comprehensive treatment plan.
How We Diagnose Sleep Apnea During Pregnancy in Nashua
Wondering, “Is there a sleep apnea dentist near me in Nashua?” Here’s exactly what to expect when you come to us:
- Initial Consultation at Our Nashua Office: Dr. Ura will review your symptoms, pregnancy history, and risk factors. We’ll complete a clinical assessment of your airway anatomy and discuss your sleep history in detail. This is a relaxed, unhurried appointment—no pressure, just information.
- Home Sleep Test or In-Lab Sleep Study Referral: Diagnosis of OSA requires an objective sleep study measuring your apnea-hypopnea index (AHI)—the number of apneic events per hour of sleep. For most patients, this can be done with a home sleep apnea test (HSAT): a compact device you wear overnight in your own bed. For complex cases, we refer to accredited in-lab polysomnography centers near Nashua, where a full suite of physiological data is collected.
- Results Review and Custom Treatment Planning: Once we have your results, Dr. Ura reviews them with you and designs a treatment plan tailored specifically to your gestational stage, severity of OSA, and personal tolerances.
- Custom Oral Appliance Fabrication: Impressions of your teeth are taken and sent to a specialized dental lab. Your custom mandibular advancement device is fabricated and fitted at a follow-up appointment, with careful calibration of the jaw advancement.
- Ongoing Monitoring Throughout Pregnancy: Your body changes every trimester. We schedule regular follow-up visits to adjust your appliance, monitor symptom response, and collaborate with your OB/GYN as needed.
Comprehensive Follow-Up Care for Expectant Mothers in Southern NH
Pregnancy sleep apnea is not a set-it-and-forget-it condition. As your pregnancy progresses, your airway anatomy, weight, and hormonal environment all continue to change. Our follow-up protocol includes:
- Appliance adjustments keyed to trimester progression—jaw position that’s ideal at 20 weeks may need recalibration at 32 weeks
- Blood oxygen monitoring to ensure treatment is achieving adequate saturation levels
- Collaboration with your OB/GYN to ensure coordinated, whole-patient care
- Post-delivery reassessment—Approximately half of women diagnosed with pregnancy-related OSA see significant improvement after delivery, particularly when pregnancy weight gain was the primary driver. However, women with pre-existing risk factors (high BMI, hypertension, and anatomical airway narrowing) often benefit from continued treatment. We reassess every patient postpartum so nothing falls through the cracks.
