A build-up of mucus in the ears can be an uncomfortable condition that’s sometimes hard to spot, especially in children, who are more prone to it due to the anatomy of their Eustachian tubes. In this article we offer a complete guide to help you better understand the problem, its causes, symptoms and treatments.
Why does mucus build up in the ears?
A build-up of mucus in the ears can be an uncomfortable, bothersome problem. Although it’s not always considered serious, when mucus builds up in the middle ear it can cause pain, temporary hearing loss, and affect balance. This is usually linked to respiratory infections or allergies that cause excess mucus production in the airways, including the area connecting the throat to the ear, known as the Eustachian tube.
The Eustachian tube is a structure connecting the throat to the middle ear, and its main job is to balance air pressure and drain fluid from the ear. However, when this tube becomes blocked, mucus and other fluids can more easily build up in the middle ear, causing the uncomfortable symptoms many people experience. This fluid can end up affecting the ear canal when it stays in the nose and sinuses for a long time, as it moves towards the canal. This is quite common in young children because their Eustachian tubes are shorter, straighter and narrower, making it very easy for mucus to move towards the ear canal, which makes it harder for fluid to drain out of the ear. This is why children are more prone to infections in this respect.
Adults can be affected too, especially those prone to allergies or colds.
Common symptoms of mucus in the ears
Spotting the symptoms of mucus in the ear helps address the problem early, reducing the risk of complications. These are the most common symptoms:
- A blocked or “full” feeling in the ear: One of the first signs of mucus in the ear is a feeling like it’s blocked, which can make it harder to hear clearly. It usually doesn’t cause pain, which is why it’s often spotted late, especially in children, since they don’t tend to complain.
A blocked-ear feeling can also make your own voice sound like it’s echoing or amplified inside your head.
- Pain or pressure: A build-up of mucus can put pressure on the middle ear, causing mild to moderate pain.
- Temporary hearing loss: Mucus in the middle ear can prevent sound from being transmitted properly, causing temporary hearing loss.
- A feeling of imbalance or vertigo: Since the ear also plays an important role in balance, a build-up of mucus can cause instability or vertigo.
- Ringing or tinnitus
- Itching
Main causes of mucus build-up in the ears
The main causes of mucus build-up in the ears can vary, from respiratory infections to allergies. The most common are:
- Respiratory infections: Colds, flu and other respiratory infections increase mucus production in the nose and throat, making it easier for it to pass into the middle ear.
- Allergies: Exposure to allergens such as dust, pollen or dust mites can cause inflammation in the airways, generating excess mucus that builds up in the Eustachian tube and, eventually, in the ear.
- Pressure changes: Situations like flying, diving or sudden changes in altitude can affect the pressure in the middle ear, causing the Eustachian tube to become blocked, making it easier for mucus to build up.
- Sinusitis: Inflammation of the sinuses can generate excess mucus in the airways, which also affects the ears.
- Anatomical differences: if there’s any anatomical difference in the Eustachian tube, a person may be more prone to mucus build-up.
- Second-hand smoke: exposure to tobacco smoke can contribute to mucus building up in the ear.
How mucus in the ears affects hearing health and balance
A build-up of mucus in the ears affects both hearing and balance. The mucus blocks sound transmission to the inner ear, leading to a temporary reduction in hearing. What’s more, the middle ear plays an essential role in balance, so when there’s a build-up of fluid and a change in pressure, it can affect the vestibular system, causing vertigo or imbalance.
In our work as hearing care specialists, when a patient describes symptoms of a blocked ear or balance problems, we use an otoscope to examine the ear canal and the eardrum. Sometimes we see bubbles of mucus behind the eardrum, a sign of possible middle ear infection. In these cases, we recommend seeing a specialist for proper treatment.
Treatments and home remedies for mucus in the ears
There are several methods that can help relieve mucus in the ears. Here are the most recommended:
- Steam inhalation: Inhaling steam from hot water can help reduce inflammation in the airways and clear the Eustachian tube, helping expel built-up mucus.
- Warm compresses: Placing a warm compress over the ear can reduce pain and help dissolve built-up mucus. This method is ideal for reducing the feeling of pressure in the ear.
- Saline solution: which can help thin the fluid.
- Ginger or eucalyptus infusions: The anti-inflammatory properties of these plants can help reduce inflammation in the airways, which can make it easier for mucus in the ear to drain.
- Exercises to drain mucus: Some exercises, such as tilting the head from side to side or chewing gum, can help unblock the Eustachian tube, encouraging mucus to drain.
Medical treatments for persistent mucus in the ears
When mucus doesn’t clear up with home remedies, medical treatment may be needed. Here are some of the most common treatments:
- Decongestants and antihistamines: These medications help reduce inflammation and excess mucus, especially if the cause is an allergy or a cold.
- Antibiotics: If the mucus build-up is the result of a bacterial infection, the doctor may prescribe antibiotics to treat it.
- Ear drainage: In more serious cases, ear drainage may be needed to remove built-up fluid. This procedure is common in children with recurring infections or in adults with chronic middle ear infections.
- Surgery: in more severe cases when medication or drainage aren’t enough.
Tips for preventing mucus in the ears
Preventing mucus build-up in the ears can improve quality of life and reduce trips to the doctor. Some practical tips for preventing mucus build-up include:
Stay hydrated: Drinking enough water helps keep mucus at the right consistency, making it easier to drain.
Avoid environments with allergens: Reducing exposure to dust, pollen and other allergens can help prevent mucus build-up in the airways.
Regular nasal hygiene: Rinsing the nose with saline solution helps keep the airways clear, preventing mucus from building up in the middle ear.
Avoid sudden pressure changes: If you need to fly or take part in activities that affect ear pressure, it’s a good idea to use techniques like chewing gum or yawning to equalise the pressure.
A build-up of mucus in the ears is a problem that, although usually not serious, can noticeably affect quality of life. Recognising the symptoms and acting with home remedies or seeking proper medical care is key to relieving pressure, reducing pain and improving hearing. From staying well hydrated to avoiding allergens and sudden pressure changes, preventive measures can be effective in stopping this discomfort from coming back.
As we learn more about how our hearing system works and its connections to the airways, we become more aware of how important it is to look after our health in this area, and to see a specialist when symptoms persist.
At our hearing centre at Juan Llorens 7 BAJO, 46008, Valencia, when a patient has had any of the symptoms mentioned above, we examine the ear canal and eardrum with an otoscope, where we often see inflammation, and in other cases that fluid behind the eardrum in the form of bubbles (the mucus), which is a sign of a middle ear infection. We immediately ask the patient to see a doctor so they can be properly examined and prescribed the right treatment.
If you’re experiencing any ear discomfort, or symptoms such as a blocked ear, pain or temporary hearing loss, don’t hesitate to visit our hearing centre. We’ll be happy to carry out a full check-up to help identify the cause and advise you on the best treatment. You can also call us on 960 659 592 to book an appointment and receive specialist care.
Frequently asked questions
Mucus builds up in the ears when the Eustachian tube becomes blocked, preventing the middle ear from draining normally. This is usually linked to colds, allergies or respiratory infections that generate excess mucus.
The most common symptoms are a blocked-ear feeling, temporary hearing loss, pressure or pain, ringing (tinnitus), itching, and balance problems or vertigo.
Yes. Mucus can block sound from being transmitted properly, causing temporary hearing loss that usually improves once the fluid build-up clears.
It’s more common in children because their Eustachian tube is shorter, narrower and more horizontal, which makes it harder for mucus to drain and easier for it to build up in the ear.
The most common causes are colds, flu, allergies, sinusitis, pressure changes (such as flying), second-hand smoke, or anatomical differences that make it harder for the ear to drain.
Some methods that can help include inhaling steam, using saline solution, applying local heat, or making movements that encourage drainage, such as chewing or moving the jaw.
When symptoms persist, or there’s pain, hearing loss or a continuous blocked-ear feeling, it’s important to see a professional to check for an ear infection or fluid build-up behind the eardrum.
