That Ringing in Your Ears Is Real — and More Common Than You Think
Tinnitus affects around 1 in 3 pregnant women due to hormonal shifts, a 40–50% increase in blood volume, and fluid retention that disrupts inner ear function (Feroz et al. (2025); Tinnitus (2024)). In most cases, it resolves or significantly reduces after delivery. New-onset tinnitus accompanied by sudden headache, visual disturbances, or swelling during pregnancy should be reported to a midwife or GP promptly, as it can signal gestational hypertension or preeclampsia.
That Ringing in Your Ears Is Real: More Common Than You Think
Noticing a new sound in your ears when you are pregnant is frightening. Your instinct is to wonder whether it means something is wrong — with you, or with your baby. That reaction makes complete sense. Pregnancy heightens your awareness of every bodily change, and tinnitus is not a symptom you can easily ignore.
Here is the reassurance you need first: ringing, buzzing, or hissing in the ears is one of the most common ear complaints in pregnancy. More than 1 in 3 pregnant women experience it (Tinnitus (2024)), compared to around 1 in 10 women of similar age who are not pregnant. For the vast majority, it is driven by identifiable physiological changes, not a sign that anything has gone seriously wrong.
This article explains what is actually happening in your body to cause the sound, gives you a clear picture of which symptoms warrant urgent medical contact, and covers what you can safely do to get some relief.
Why Pregnancy Causes Tinnitus: Three Distinct Pathways
Pregnancy puts your cardiovascular and hormonal systems under significant demand, and your inner ear is sensitive to both. There are three main physiological routes through which these changes produce tinnitus.
Hormonal changes and the inner ear
Oestrogen and progesterone rise substantially during pregnancy and directly influence the fluid environment of the cochlea, the spiral structure in your inner ear that converts sound waves into nerve signals. These hormones alter how nerve cells in the auditory pathway respond to sound. When that balance shifts, the brain can begin generating phantom sounds (Swain et al. (2020)).
Cardiovascular changes and pulsatile tinnitus
Blood volume increases by 40–50% during pregnancy to support the placenta and growing baby (Tinnitus (2024)). This raises the pressure of fluid within the cochlea and increases blood flow through the vessels surrounding the inner ear. For some women, the result is pulsatile tinnitus: a rhythmic sound that pulses in time with the heartbeat. If the sound you are hearing has a pulse or beat to it rather than being a steady tone, mention this specifically to your midwife or GP, as it may warrant a cardiovascular check.
Fluid retention and endolymphatic hydrops
Pregnancy causes widespread fluid retention, and the inner ear is not exempt. Increased fluid in the membranous labyrinth raises pressure in the endolymph, the fluid that fills the inner ear’s balance and hearing chambers. Researchers have compared this mechanism directly to Ménière’s disease, which is caused by a similar build-up of endolymphatic pressure (PMC (2022)). This is why some pregnant women also experience a sensation of ear fullness or mild dizziness alongside tinnitus.
A correctable fourth factor: iron-deficiency anaemia
Iron-deficiency anaemia is common in pregnancy, and it is worth knowing that anaemia can independently contribute to tinnitus. If your prenatal blood tests show low iron, treating the anaemia may reduce the tinnitus alongside it.
One more figure worth knowing: if you had tinnitus before becoming pregnant, the odds are that pregnancy will make it louder or more persistent. Two in three women with pre-existing tinnitus report their symptoms worsen during pregnancy, particularly in the second trimester (Tinnitus (2024)).
When to Act Immediately: The Preeclampsia Red Flag
Tinnitus alone, without any other symptoms, is not an emergency. Raise it at your next midwife appointment, but there is no need to call 999 or rush to A&E.
The picture changes when tinnitus appears alongside other symptoms. Tinnitus can be an early warning sign of gestational hypertension and preeclampsia, a serious condition affecting approximately 3–5% of pregnancies in the UK (NICE (2019)). International clinical guidelines list tinnitus explicitly among the urgent warning signs of hypertensive disorders in pregnancy (MSF (2023)).
Contact your midwife, maternity unit, or GP the same day — or call 999 if symptoms are severe — if tinnitus occurs alongside any of the following:
- Sudden or severe headache
- Visual disturbances: blurred vision, flashing lights, or seeing spots
- Severe pain just below your ribs
- Nausea or vomiting alongside the above
- Sudden swelling of your face, hands, or feet
- Reduced fetal movement
These are the official emergency symptoms listed in NICE guidance for preeclampsia (NICE (2019)), and tinnitus appearing in this cluster adds urgency to any of them.
If your tinnitus is a steady tone without any of the symptoms above, the appropriate step is to mention it at your next scheduled appointment. You do not need to catastrophise, but you should not dismiss it either. Telling your midwife means it gets noted in your records and monitored.
If you experience tinnitus together with sudden severe headache, visual disturbances, severe pain below your ribs, or sudden facial or hand swelling, contact your midwife or maternity unit the same day. If symptoms are severe, call 999. These may be signs of preeclampsia.
Which Trimester? How Tinnitus Changes Through Pregnancy
Tinnitus can begin at any point in pregnancy, but the pattern across trimesters follows the body’s physiology fairly closely.
In the first trimester, rapid hormonal shifts can trigger early-onset tinnitus, often alongside other vestibular symptoms like dizziness (PMC (2022)). Many women also notice ear fullness during this phase.
The second and third trimesters bring the highest burden. A large prospective study of 1,230 pregnant women found tinnitus most common in the third trimester, when blood volume and fluid retention are at their peak (Feroz et al. (2025)). Women with pre-existing tinnitus tend to notice a worsening particularly in months four to six (Tinnitus (2024)).
What about after delivery and during breastfeeding?
This is an aspect that rarely gets covered, but it matters. For most women, tinnitus improves or resolves within weeks of delivery as hormones and blood volume normalise. A comparison of 33% tinnitus prevalence in pregnancy versus 11% in non-pregnant women of similar age, with relief documented after delivery, supports this pattern (Swain et al. (2020)).
If tinnitus does not disappear immediately after birth, that does not mean it is permanent. The postpartum and breastfeeding period involves significant ongoing hormonal flux, and sleep deprivation and new-parent stress compound matters further. Tinnitus may persist or temporarily change during this phase (Tinnitus (2024)). Allow several weeks to months after delivery, or after breastfeeding ends, before drawing any conclusions about whether the tinnitus is here to stay. If it persists beyond that point, a referral for a full hearing assessment is the right next step.
If you are still experiencing tinnitus weeks after giving birth, you are not alone. The postpartum hormonal transition takes time, and tinnitus often lags behind the delivery itself. Mention it at your postnatal check if it has not resolved.
Safe Ways to Manage Tinnitus During Pregnancy
No pregnancy-specific clinical trials have tested tinnitus management strategies, so the guidance below is based on general tinnitus evidence, known safety profiles in pregnancy, and clinical consensus. The aim is relief, not a cure, and several options are both safe and practical.
Sound enrichment
Using background sound to reduce the contrast between silence and the tinnitus signal is one of the most widely recommended strategies in tinnitus management, and it carries no drug interactions or risks in pregnancy. White noise machines, a fan, nature soundscapes, or low-volume background music can all help, particularly at night when tinnitus tends to be most disruptive. Sound enrichment apps on a smartphone work equally well.
Stress and sleep management
Stress amplifies tinnitus perception, and pregnancy brings its own pressures. Prenatal yoga, guided breathing, and mindfulness practices are generally safe in pregnancy and may reduce the distress associated with tinnitus, even if they do not reduce the sound itself. Your midwife or GP can advise on local classes.
Dietary iron and prenatal vitamins
If blood tests suggest iron-deficiency anaemia, addressing it through diet (dark leafy greens, red meat, legumes, fortified cereals) and your prescribed prenatal vitamins is worthwhile. Iron-deficiency anaemia is independently associated with tinnitus and can be corrected safely during pregnancy under your care team’s guidance.
Hydration
Adequate fluid intake supports overall circulatory health and may help moderate the fluid retention effects that contribute to inner ear pressure changes. Aim for the recommended daily fluid intake for pregnancy.
When to seek a hearing assessment
If tinnitus is causing significant distress, is affecting your sleep night after night, or is accompanied by any change in your hearing, ask for a referral to audiology through your midwife or GP. This is a legitimate clinical request, not an overreaction.
For safe tinnitus relief during pregnancy: use background sound at night, manage stress with prenatal mindfulness or yoga, ensure your iron levels are checked, and stay well hydrated. None of these carry risks in pregnancy.
What to avoid or discuss with your doctor first
Some commonly suggested tinnitus remedies are not appropriate during pregnancy:
- Ginkgo biloba: Frequently marketed for tinnitus, but considered likely unsafe in pregnancy due to an increased risk of bleeding and possible stimulation of early labour. Do not take it without explicit approval from your prescriber.
- High-dose vitamin supplements: Beyond your prescribed prenatal vitamins, high-dose single vitamins (including high-dose zinc) have not been established as safe or effective for tinnitus in pregnancy. Stick to your prescribed supplement.
- Any over-the-counter medication: Always check with your GP or midwife before taking any OTC remedy for tinnitus symptoms during pregnancy.
Most Pregnancy Tinnitus Resolves, But You Don’t Have to Wait It Out Alone
Tinnitus during pregnancy is common, physiologically explained, and in most cases temporary. It is not a sign that something is wrong with your baby, and for the large majority of women it reduces or disappears after delivery or during the weeks that follow.
You now know which symptoms alongside tinnitus require same-day contact with your maternity team or GP. You know that a steady tone without other red-flag symptoms is worth noting at your next appointment rather than rushing to A&E. And you have a set of practical, pregnancy-safe strategies to make the sound more manageable while you wait for your body to settle.
Do not file this away as a minor complaint you hesitate to mention. Tinnitus in pregnancy is a legitimate clinical concern, and your midwife needs to know about it. Mention it at your next appointment, and if any of the red-flag symptoms appear alongside it, do not wait.
