What are ear infections?

Otitis Externa

There are two main types of ear infections. The first is called outer ear infection, swimmer's ear would be an example of this. It affects the ear canal, which goes from the ear opening to the eardrum. An outer ear infection occurs when water enters the ear canal and becomes trapped there by wax build-up. This creates an ideal environment for bacteria to flourish. The body responds to the infection with inflammation, pain, redness, and sometimes a fever.
 

Otitis Media

The second type is called a middle-ear infection or otitis media. They occur when either virus or bacteria cause infection in the middle ear. The condition can be a result of the tubes inside the ears becoming clogged with mucus and fluid. Middle ear infections can be excruciating and are often accompanied by high fever, hearing difficulty, nausea, and vomiting. The fluid build-up can lead to hearing loss as all that ear fluid prevents sound from getting through. 

This type of ear infection is much more common, particularly in very young children and infants. When babies and young children pull or slap at their ears, an ear infection is quite possible. Most middle ear infections are linked to an upper respiratory infection or an allergy. Forty percent of cases are thought to be caused by bacteria, the rest by a virus.

These are some of the most common symptoms of otitis media. Not all of them need to be present for a diagnosis of ear infection. 

• Ear pain, often throbbing 
• Fever 
• Pressure or a feeling of fullness in the ear 
• Pus from the ear 
• Hearing difficulty in the affected ear 
• Nausea and vomiting

There are four main types of otitis media: 

• acute otitis media
• recurrent acute otitis media
• otitis media with effusion (OME)
• chronic otitis media with effusion. 

Acute otitis media comes on rapidly and is defined by swelling and redness in the ear behind and around the eardrum. Ear pain, fever, and partial or complete hearing loss often occur as a result of fluid or mucus caught in the middle ear. Repeated episodes of middle ear infections are called recurrent acute otitis media. Otitis media with effusion (OME) is the presence of fluid in the middle ear without any signs or symptoms of acute infection. This can happen when the infection clears up, but mucus and fluid continue to build up in the middle ear. This build-up creates a feeling of fullness in the ear, reducing your ability to hear clearly.  OMEs typically resolve on their own. OME is said to be chronic when middle ear effusion has been present for at least three months.

One of the reasons infants and young children get otitis media so often is connected to the eustachian tube. Because the eustachian tube is more horizontal than it is in adults, it prevents fluid to flow smoothly. When it isn't working properly, mucus is unable to drain from behind the eardrum. Instead, it stays stuck and causes pain and pressure. This situation often leads to infection. As children get older, the eustachian tube becomes more vertical and begins to drain better.

The key to preventing otitis media is to limit the build-up of fluid. Proper diet can play an essential role in reducing the risks. Food allergens, such as cow's milk and sugar, lead to excess mucus and fluid. Eliminating these foods from the diet can be helpful. 

Reducing exposure to environmental allergens, such as secondhand smoke, is also essential. Cigarette smoke creates an environment for bacteria and virus to thrive.

There are several things you can do to help relieve your symptoms related to a middle ear infection. Increasing your water intake is one important step you can take to assist your body with clearing the infection. You should drink plenty of water to help flush bacteria and viruses out of the body.

Diet plays a vital role in helping to relieve symptoms of otitis media. Follow these dietary suggestions to help alleviate pain and prevent recurring infections. You may need to make drastic changes in your child's diet for optimal results.
 

Recommended Foods

You can help your body clearing a middle ear infection by strengthening your immune system. 

• Follow a healthy diet centered around fresh fruits, vegetables, whole grains, and high-quality protein, will make your immune system stronger.
• Drink plenty of clean, quality water to thin mucus secretions. 
• Essential fatty acids, found in cold-water fish, flaxseeds, and flaxseed oil, are useful in reducing the inflammation or the allergies that are often present. 
• Switch bottle-fed babies to a nondairy formula, with your doctor's supervision. 
• Breastfeeding mothers should avoid common allergens, such as cow's milk.

• Do not bottle-feed while children are lying on their backs. They should be at a thirty-degree angle or more to prevent fluid accumulation in the eustachian tube. 
• Do not smoke or expose yourself or your child to secondhand smoke. 
• Avoid using cotton swabs, as they pack wax into the ear canal. 
• During an infection, don't allow moisture into your ears. 
• To decrease pain, apply heat locally. Try a hot-water bottle wrapped in a towel or blow a hairdryer onto the affected ear.

If middle ear infection occurs frequently, it can lead to severe consequences. The formation of scar tissue on the eardrum is one such complication. The scar tissue can lead to hearing difficulty and eventually ruptured eardrums. If the tiny ear bones called ossicles in your inner ear are damaged or deformed, this can cause hearing loss.
