Understanding Ear Infections

Ear infections can occur in different parts of the ear– the outer ear (otitis externa), the middle ear (otitis media), and the inner ear (otitis interna). Each type of infection has distinct causes and symptoms.

Adults with ear infections may experience a range of symptoms, including:

  • Ear pain or discomfort
  • Hearing loss or feeling of fullness in the ear
  • Fluid drainage in the ear
  • Itching in the ear canal
  • Fever, in some cases

Causes of Adult Ear Infections

Here are a few common causes of ear infections in adults:

Bacterial and Viral Infections

Most ear infections in adults are due to bacteria or viruses. Upper respiratory infections, such as colds and flu, can lead to ear infections. When a viral or bacterial infection inflames the Eustachian tube (which connects the middle ear to the throat), it can cause fluid to build up in the middle ear, creating an environment conducive to bacterial growth. Sinus infections can often lead to an ear infection, as the sinuses are connected to the ear which allows for bacteria to spread.

Allergies

Allergies can cause ear infections by triggering inflammation and fluid buildup in the Eustachian tubes. This is particularly common in individuals with seasonal allergies or chronic allergic conditions. Allergies often cause an increase in mucus production in the nasal passages and throat. This excess mucus can cause fluid buildup in the middle ear, leading to infection.

Swimming and Water Exposure

Known as swimmer’s ear (otitis externa), this type of ear infection occurs when water remains in the ear canal– creating a moist environment ideal for bacterial growth. Adults who swim frequently or expose their ears to water without proper drying can develop swimmer’s ear infections.

Injuries or Irritation

Injuries or irritation in the ear canal can also lead to infections. One of the most common causes of ear canal injuries is the use of cotton swabs or other objects to clean the ear. These objects can scratch the skin lining the ear canal, creating entry points for bacteria which leads to infection.

When To Seek Medical Attention

If you’re experiencing any symptoms indicative of an ear infection, it’s important to seek medical attention– especially if your symptoms persist or worsen. Untreated ear infections can lead to complications, including hearing difficulties and the spread of infection. At an urgent care center, a certified healthcare provider can offer prompt and effective treatment for ear infections. Your medical provider will diagnose the cause of your infection and recommend the best course of action to ensure a quick recovery. Bacterial infections can be treated with antibiotics, while viral infections can be alleviated with supportive care remedies.
