Know How An Ear Infection Starts And What You Can Do About It
Written by Medicover Team and Medically Reviewed by Dr Nikitha Reddy , ENT
Ear infections are a common reason for doctor visits, especially in young children. They often develop quickly after a cold or respiratory illness and can cause discomfort, irritability, and hearing issues. While most are treatable, timely care is important to prevent complications and ensure a full recovery.
What is Ear Infection(otitis media)?
An ear infection, also known as acute otitis media, is a condition in which bacteria or viruses cause inflammation and fluid buildup inside the ear, most commonly in the middle ear, located behind the eardrum. This can result in earache, hearing difficulties, fever, or even fluid discharge from the ear.
Ear infections are prevalent in infants and toddlers, but they can occur at any age. Most mild ear infections improve on their own or with antibiotics. At the same time, recurrent or chronic diseases may require additional medical care to prevent complications, such as hearing loss or eardrum damage.
How Common are Ear Infections?
Ear infections are prevalent, especially in young children. Around 5 out of 6 children will have at least one ear infection by the age of 3. They are a leading cause of doctor visits and antibiotic use in childhood.
Although more common in children, adults can also develop ear infections, particularly after experiencing colds, allergies, or sinus infections.
Recurrent cases are more likely to occur in individuals with weakened immune systems or ongoing respiratory issues.
Why Are Children More Likely to Get Ear Infections Than Adults?
Children are more prone to ear infections because their eustachian tubes (which connect the middle ear to the throat) are shorter, narrower, and more horizontal.
This makes it easier for germs and fluids to get trapped. Also, their immune systems are still developing, so they don't fight infections as effectively. Frequent colds, exposure to other children, and bottle-feeding while lying down also increase the risk of illness.
What are the Symptoms of an Ear Infection?
The symptoms of ear infection in adults are:
The symptoms of ear infection in Infants and children are:
- Ear pain
- Tugging at the ear
- Trouble sleeping
- Fever
- Irritability or fussiness
- Crying more than usual, especially at night when lying down
- Fluid or drainage from the ear (possibly a torn eardrum)
- Trouble hearing or responding to sounds
- Loss of balance
- Headache
- Loss of appetite
What are the Causes of Ear Infection?
Ear infections are often caused by bacteria in the middle ear, although viruses can also contribute to their development. It causes a buildup of fluid in the middle ear spaces. The discomfort is caused by the fluid buildup and inflammation that puts pressure on the eardrum. Some common causes include:
- Bacterial or Viral Infections: The most frequent cause of ear infections is a bacterial or viral infection, often following a cold, sinus infection, or respiratory infection. These infections can lead to fluid accumulation in the middle ear, resulting in pain and inflammation.
- Earwax Buildup: An excessive amount of earwax can block the ear canal, trapping bacteria and moisture, which can lead to an infection known as otitis externa (swimmer's ear).
- Upper Respiratory Infections: Colds and flu can cause the Eustachian tube, which connects the middle ear to the throat, to become blocked, leading to pressure and fluid buildup in the middle ear infection.
- Weakened Immune System: Conditions that weaken the immune system, such as diabetes or HIV, can increase an individual's susceptibility to ear infections.
What Are The Risk Factors For Ear Infections?
The following are risk factors for ear infections:
- Age Ear infections are more common in infants and young children (between the ages of 6 months and 2 years).
- Colds Having a cold increases the likelihood of getting an ear infection.
- Allergies induce inflammation (swelling) of the nasal passages and upper respiratory system, which can cause the adenoids to expand. Enlarged adenoids can clog the eustachian tube, preventing ear fluids from draining.
- People with chronic diseases, particularly those with immune deficiencies and chronic respiratory disorders such as cystic fibrosis and asthma, are more prone to developing ear infections.
- Ear infections are more common during cold and flu season when respiratory diseases are more prevalent.
- Exposure to environmental pollutants, including smoke, dust, and chemicals, can irritate the Eustachian tube, making the ear more susceptible to infection.
- Extended use of a pacifier in young children has been associated with an increased risk of ear infections, as it can affect the pressure in the Eustachian tube.

Get Second OpinionHow is an Ear Infection Diagnosed?
An ear infection is typically diagnosed through a simple physical examination, especially in children. The doctor looks for signs of fluid buildup, inflammation, or pressure in the middle ear.
Standard Tests Used to Diagnose an Ear Infection
- Otoscope Exam: The doctor uses a lighted instrument called an otoscope to examine the inside of the ear. They check for a red, swollen, or bulging eardrum and any fluid behind it.
- Pneumatic Otoscopy: A small puff of air is blown into the ear to see if the eardrum moves normally. Limited movement may suggest fluid buildup, a sign of infection.
- Tympanometry: This test measures the eardrum's ability to move in response to changes in air pressure. It helps detect fluid in the middle ear even when it's not visible.
Other or Additional Tests (Used When Needed)
- Acoustic Reflectometry: This test utilises sound waves to assess the presence of fluid behind the eardrum by measuring the amount of sound that bounces back.
- Hearing Test (Audiometry): Recommended for children with frequent ear infections or suspected hearing loss. It assesses how well the ear is working.
- Tympanocentesis: A minor procedure where fluid is drawn from the middle ear using a needle for lab testing. Used in severe or treatment-resistant cases.
- CT or MRI Scan: These imaging tests are only used if complications are suspected, such as the spread of infection to nearby bones or tissues (e.g., mastoiditis).
What are the Treatment Options for Ear Infections?
Treatment for an ear infection depends on the severity of symptoms, the patient's age, and whether a bacterium or a virus causes the infection. Here's how it's typically managed:
Home Treatment for Ear Infections
Mild ear infections, especially those caused by viruses, can often be managed at home. Supportive care focuses on symptom relief.
- Warm compress over the ear to reduce pain
- Over-the-counter pain relievers like acetaminophen or ibuprofen (as advised)
- Rest and fluids to help the body recover
- Elevating the head (in older children and adults) to relieve pressure
- Monitoring symptoms for a few days, as many ear infections clear on their own within 2-3 days
Note: Avoid inserting oils, drops, or objects into the ear without medical guidance.
Medical Treatment for Ear Infections
If symptoms persist or worsen, medical intervention may be necessary, especially for ear bacterial infections.
- Antibiotics (e.g., amoxicillin) if the infection is bacterial or not improving
- Prescription ear drops (for outer ear infections or ruptured eardrums)
- Decongestants or antihistamines in case of underlying allergies or congestion
- Follow-up exams to ensure the infection has cleared
- Surgical drainage (myringotomy) in severe or chronic cases
Medical Treatment in Infants & Children
Children are more prone to ear infections due to shorter and more horizontal eustachian tubes. Ear Infection treatment in children is carefully managed based on age and symptoms.
- Watchful waiting: For children over 2 years with mild symptoms, doctors may wait 48–72 hours before prescribing antibiotics
- Antibiotics: Usually given to children under 2 years or with high fever, severe pain, or recurrent infections
- Pain relief: Age-appropriate doses of acetaminophen or ibuprofen
- Ear tubes (tympanostomy tubes): Considered if a child has frequent infections or persistent fluid buildup affecting hearing or speech
Pediatric care focuses on preventing complications of otitis media, such as hearing loss or speech delays.
When to See a Doctor for an Ear Infection(Otitis Media)
You should see a doctor if:
- Ear pain is severe or lasts more than 1-2 days
- Fever is 101°F (38.3°C) or higher, especially in children
- Fluid, pus, or blood drains from the ear
- Hearing problems or a feeling of fullness in the ear persist
- Your child is under 6 months old and shows signs of ear discomfort
- Symptoms return after initial improvement
- Balance problems, stiffness in the neck, or facial weakness develop
- Ear infections occur frequently (3 or more in 6 months or 4 in a year)
Prompt treatment can prevent complications such as hearing loss, the spread of infection, or a ruptured eardrum. Always consult a healthcare provider if you're unsure about your or your child's symptoms.
