sudden ear

Overview

Sudden hearing loss is when you lose your hearing quickly, usually in one ear, over a few hours or days. It can be a scary experience, but many people recover fully with prompt medical care.

It is not very common, but it is a well-known condition. Around 5 to 20 in every 100,000 people experience sudden hearing loss each year.

It can happen at any age, but it is most often seen in adults between 40 and 60 years old. It affects men and women equally.

Symptoms

Common symptoms

• A sudden loss of hearing in one ear
• A popping or crackling sound just before the hearing loss
• Ringing in the ear, also called tinnitus
• A feeling of fullness or pressure in the ear
• Dizziness or balance problems

Symptoms in children

• Children may not be able to describe their symptoms clearly
• They might not respond when called, or seem to ignore you
• They may turn up the TV or speak louder than usual
• They might complain of ear pain or a blocked feeling

Symptoms in older adults

• Hearing loss may appear as confusion or not understanding conversations
• Older adults may withdraw from social events because of difficulty hearing
• They may feel that their ear is suddenly blocked or full
• Balance problems may increase the risk of falls

Causes

Main causes

• Often no clear cause can be found
• Viral infections that affect the inner ear, such as influenza or other infections
• Reduced blood flow to the inner ear
• Head injury or trauma
• Autoimmune diseases, where the immune system mistakenly attacks the inner ear
• Exposure to a very loud noise

Risk factors

• Being between 40 and 60 years old
• Having diabetes, heart disease, or high blood pressure
• Smoking
• A history of migraines or ear infections
• Recent exposure to extremely loud sounds

When to see a doctor

See a doctor urgently if:

• Any sudden hearing loss – see a doctor the same day or go to the emergency room
• Sudden hearing loss with dizziness, ringing, or pain

Book a routine appointment if:

• If you have a gradual hearing loss that lasts longer than a week
• If you have a feeling of fullness in the ear that does not go away

Diagnosis

A doctor will ask about your symptoms and do a simple hearing test. They will also look inside your ear with a special light to check for blockages, infection, or other issues.

Tests that may be done

• A hearing test called an audiogram
• A test that measures how your eardrum moves, called tympanometry
• Blood tests to check for infection or autoimmune conditions
• An MRI scan to rule out tumors or other inner ear problems

What to expect at your appointment

You may be referred to an ear, nose, and throat specialist, also known as an ENT doctor. The diagnosis is usually straightforward, but extra tests may be needed to find the cause and plan the best treatment.

Treatment

Treatment works best when started quickly. The goal is to reduce inflammation in the inner ear and help your body heal. Some people improve on their own, but you should always see a doctor for sudden hearing loss to avoid permanent damage.

Self-care at home

• Rest your ear by avoiding loud noise and keeping the ear dry
• Do not use ear drops or clean the ear canal with cotton swabs
• Keep a simple record of your symptoms to share with your doctor

Medical treatments

Doctors often use oral steroids to reduce inner ear swelling. In some cases, they may inject steroids directly into the middle ear. Antiviral medicines may be used if a viral infection is suspected. Always ask your healthcare provider to explain the benefits and risks of any treatment.

When is surgery considered?

Surgery is not usually needed for sudden hearing loss itself. However, if the cause is a tumor or a head injury, your doctor may discuss surgical options with you.

Living with this condition

If your hearing does not fully return, you can adjust by letting friends and family know. Face the person you are talking to, reduce background noise, and consider assistive listening devices. Hearing rehabilitation services can teach you new ways to communicate.

Lifestyle tips

• Avoid loud music and noisy environments
• Wear ear protection if you attend concerts or work with loud machines
• Learn ways to manage stress, such as deep breathing, light exercise, or spending time on hobbies

Diet and exercise

Eating a balanced diet with fruits, vegetables, and whole grains supports overall health. Regular exercise can improve blood flow, but check with your doctor before starting any new activity.

Mental health and emotional wellbeing

Sudden hearing loss can make you feel isolated, anxious, or sad. These feelings are normal. Talk to your healthcare team about your emotions and ask about counseling or peer support groups.

Prevention

There is no guaranteed way to prevent sudden hearing loss, but you can lower your risk by protecting your ears from loud noise, managing conditions like diabetes and high blood pressure, and avoiding smoking.

Vaccines

Some infections that can cause ear problems are preventable with vaccines. Ask your doctor if you are up to date on recommended vaccinations.

Screening programmes

There is no routine screening for sudden hearing loss. However, if you notice any change in your hearing, do not wait – seek help early.

Complications

If left untreated

• Permanent hearing loss
• Problems with balance and a higher risk of falls
• Difficulty communicating, which can lead to loneliness or depression

Long-term outlook

The outlook is hopeful. Many people recover some or even all of their hearing, especially if they receive treatment within the first few days. Even if hearing loss remains, hearing aids, counseling, and rehabilitation can help you live a full and active life.
