What the Eustachian Tube Actually Does
Before the symptom makes sense, the structure does. The Eustachian tube is a narrow canal that connects the middle ear to the back of the nose and upper throat. Its job is simple but essential:- It equalises air pressure on both sides of the eardrum.
- It allows fluid from the middle ear to drain into the throat.
- It opens briefly when you swallow, yawn, or chew.
During pregnancy, the tube itself does not change shape. The tissues around it do.
Why Pregnancy Makes Eustachian Tube Congestion More Likely
This symptom is rarely random. Several pregnancy-specific changes converge in the ear and nasal passages.- Hormonal swelling of mucous membranes: Rising oestrogen levels increase blood flow to mucous membranes across the body, including the nose, throat, and middle ear. These tissues become thicker and more congested, narrowing the opening of the Eustachian tube.
- Increased blood volume and fluid retention: By the second trimester, your blood volume increases significantly. Excess fluid can accumulate in small, delicate spaces such as the middle ear lining, reducing drainage efficiency.
- Pregnancy rhinitis: Many women develop nasal congestion without infection or allergy during pregnancy. This persistent stuffiness can extend backwards toward the Eustachian tube opening, impairing ventilation.
- Relaxation of smooth muscle tone: Hormonal shifts affect muscle tone throughout the body. The muscles that open the Eustachian tube may not contract as efficiently, making pressure equalisation more difficult.
- Postural effects: Fluid shifts when you lie flat, especially at night. This is why ear fullness often worsens when you lie on one side or wake up in the morning.
What It Typically Feels Like
The sensation varies, but most women describe a combination of the following:- A blocked or plugged feeling in one or both ears
- Mild hearing dullness rather than true hearing loss
- Popping or crackling when swallowing or yawning
- Pressure without sharp pain
- A sense that sound is echoing or distant
- Symptoms that fluctuate during the day
When It Is More Common During Pregnancy
Although it can occur at any stage, many women report patterns.- First trimester: Hormonal changes can trigger early nasal congestion, occasionally affecting the ears.
- Second trimester: Increased blood volume and fluid retention often make symptoms more noticeable.
- Third trimester: Postural effects, sleep position, and fluid shifts can intensify pressure sensations.
How This Is Different From an Ear Infection
It is easy to confuse Eustachian tube congestion with infection, but there are differences.Eustachian tube congestion usually involves:
- Pressure or fullness
- Mild hearing changes
- No fever
- No discharge
- Symptoms that improve briefly with swallowing or yawning
An ear infection is more likely if there is:
- Sharp or throbbing pain
- Fever or general illness
- Pus or fluid leaking from the ear
- Persistent pain that worsens rather than fluctuates
How Doctors Evaluate Blocked Ears in Pregnancy
Diagnosis is usually clinical. Your doctor may:- Ask about nasal congestion, allergies, and recent infections
- Examine the ear with an otoscope to check the eardrum
- Look for fluid behind the eardrum or signs of infection
- Examine the nose and throat for swelling
Safe Ways to Ease Eustachian Tube Congestion During Pregnancy
Management focuses on reducing swelling and improving drainage, not forcing the ear open.- Gentle swallowing and jaw movements: Frequent swallowing, chewing sugar-free gum, or gentle jaw movements can facilitate tube opening.
- Steam inhalation: Warm steam can temporarily reduce nasal and throat congestion, indirectly improving Eustachian tube function.
- Saline nasal sprays or rinses: Plain saline helps thin mucus and reduce swelling without medication. These are generally considered safe during pregnancy.
- Sleeping position adjustments: Sleeping with your head slightly elevated may reduce fluid pooling around the ear and throat overnight.
- Adequate hydration: Proper hydration helps maintain thinner secretions and better drainage.
- Avoid forceful pressure techniques: Strong nose-blowing or aggressive pressure manoeuvres can irritate the ear and worsen symptoms.
What Usually Does Not Help
Understanding what not to rely on prevents frustration.- Antibiotics, unless there is a clear infection
- Repeated ear drops when the issue is pressure, not the ear canal
- Aggressive popping attempts
- Ignoring persistent symptoms for weeks without evaluation
Emotional Impact You Might Not Expect
A blocked ear can feel surprisingly distressing. Constant pressure affects sleep, concentration, and emotional balance. In pregnancy, when your sensory threshold is already heightened, this can feel overwhelming.You may worry about hearing damage or long-term effects. The uncertainty itself can cause anxiety, especially when reassurance is vague.
It is important to note that pregnancy-related Eustachian tube congestion is usually transient and resolves after delivery, as fluid balance and hormones stabilise.
When to Seek Medical Review
Although the condition is usually benign, certain signs need evaluation.Contact your doctor if you notice:
- Persistent blockage lasting several weeks
- Significant hearing loss rather than mild muffling
- Pain that increases or becomes sharp
- Fever or flu-like symptoms
- Fluid or blood from the ear
- Dizziness or balance problems
What Happens After Delivery
For most women, symptoms gradually ease in the weeks following birth. As hormone levels fall and excess fluid is mobilised, mucosal swelling decreases. Eustachian tube function normalises, often without any intervention.If symptoms persist well into the postpartum period, an ENT evaluation may be recommended, especially if nasal congestion or sinus issues continue.

FAQs on Why Your Ears Feel Blocked During Pregnancy and What Eustachian Tube Congestion Has to Do With It
- Can blocked ears during pregnancy harm my baby?
No. Eustachian tube congestion affects pressure balance in your ears only and does not impact the baby. - Is it safe to use nasal sprays for this problem?
Plain saline sprays are generally safe. Medicated sprays or decongestants should only be used if your doctor approves. - Why does one ear feel more blocked than the other?
Anatomical differences, sleeping position, or uneven nasal congestion can affect one side more.
