Glue Ear (Otitis Media with Effusion) in Adults: Symptoms & Treatment

Glue ear, medically known as Otitis Media with Effusion (OME), is a condition where the middle ear—the area behind the eardrum—becomes filled with a thick, glue-like fluid. Unlike a standard middle ear infection (acute otitis media), glue ear is typically not painful and does not involve a bacterial or viral infection of the fluid itself.

In a healthy ear, the Eustachian tube drains fluid and equalises pressure. If this tube becomes blocked or fails to function correctly, a vacuum is created, causing fluid to seep from the surrounding tissue into the middle ear. In the United Kingdom, glue ear is one of the leading causes of temporary hearing impairment. While most famous for affecting toddlers, it is a significant concern for adults, particularly during the winter flu season or high-pollen months.

Adults often describe glue ear as the feeling of being 'underwater' or having 'cotton wool' stuffed in their ears. Because the fluid prevents the eardrum from vibrating freely, the most common symptom is conductive hearing loss.

• Muffled hearing: Sounds seem quiet or distant, which may fluctuate throughout the day.
• Ear pressure: A persistent feeling of fullness or heaviness in one or both ears.
• Tinnitus: Hearing ringing, buzzing, or humming sounds that originate inside the ear.
• Popping or clicking: Occasional sensations of the ear 'opening' briefly, especially when swallowing or yawning.
• Mild balance issues: Some patients report feeling slightly unsteady, though true vertigo is rare with OME.

In British clinical practice, GPs look for specific triggers that cause the Eustachian tube to malfunction. In adults, glue ear rarely appears without a preceding cause. Common triggers include:

Respiratory Infections

The common cold, influenza, and sinusitis are the most frequent culprits. Inflammation in the nasopharynx can block the Eustachian tube opening, leading to fluid accumulation.

Allergies

Hay fever (allergic rhinitis) or reactions to dust mites and pets can cause the lining of the ear tubes to swell, preventing proper drainage.

Smoking

Exposure to tobacco smoke irritates the delicate cilia (tiny hairs) in the respiratory tract and ear tubes, hindering their ability to clear mucus. This is a significant risk factor noted in NICE (National Institute for Health and Care Excellence) guidelines.

Pressure Changes

Rapid changes in air pressure, such as those experienced during flying (barotrauma) or scuba diving, can trigger effusion if the ears cannot equalise quickly enough.

According to NHS guidance, the first line of management for glue ear is often 'active observation.' Because many cases follow a viral cold, the fluid usually drains naturally within six to twelve weeks.

Self-Care Strategies

Patients can try the Valsalva manoeuvre—closing the mouth, pinching the nose, and gently blowing to force air into the Eustachian tubes. Auto-inflation devices (Otovent) are also available in UK pharmacies; these involve blowing up a medical-grade balloon through the nose to help open the ear tubes.

Medication

If allergies are the suspected cause, a GP may recommend antihistamines or steroid nasal sprays to reduce inflammation. Decongestants may provide short-term relief for the nose, though they have limited effectiveness in clearing the ear fluid itself.

Surgical Intervention

If the condition persists beyond three months and significantly impacts quality of life, a referral to an ENT (Ear, Nose, and Throat) specialist may be necessary. Procedures include the insertion of grommets (tiny ventilation tubes) or, in some cases, an adenoidectomy if enlarged tissue is blocking the tubes.

If you are experiencing persistent muffled hearing or a feeling of fullness that has lasted more than two weeks, you should speak to a GP online or in person. A consultation is particularly important to rule out other causes of hearing loss, such as earwax impaction or a perforated eardrum.

An online doctor can review your symptoms, discuss your medical history (such as recent colds or allergies), and provide advice on the most appropriate treatments available in the UK. They can also issue private prescriptions for nasal steroids if deemed necessary or provide a sick note if your hearing loss is impacting your ability to work safely, especially in communication-heavy roles.

It is vital to distinguish between glue ear (OME) and a standard middle ear infection (Acute Otitis Media). While glue ear is characterised by fluid, an acute infection involves infected fluid. A middle ear infection typically presents with sharp, throbbing pain, a high temperature (fever), and a red, bulging eardrum. Glue ear, by contrast, is usually painless, though the pressure can be uncomfortable. If you develop a fever or discharge from the ear, you likely have an infection that may require antibiotics, whereas glue ear does not.
