What Are the Top Causes of Ear Infections?

If you’re feeling ear pain, diminished hearing, and headaches, you might have an acute otitis media called ear infections. According to the Mayo Clinic, acute otitis media results from bacteria or a viral infection affecting the middle ear, where the vibrating bones are. The inflammation and accumulation of fluids handle some of those unpleasant symptoms.

To further understand what we can do about it, we need to know what puts us in this uncomfortable and potentially dangerous situation.

Uncovering the roots of the earaches

Ear infections are often the byproduct of a cold, the flu, or an allergy. These diseases cause inflammation in the throat, nasal system, and Eustachian tubes, which infect the middle ear. Some people believe that a cold is a major responsibility, and they are partially right.

Trung Tristan Truong, MD, FAAP from Memorial Care, tells of a Yale study (2014) that when the temperatures are low, “… cold viruses can replicate more efficiently and the body’s immune system fighting these cold viruses may be diminished.” Thus, “… upper respiratory infections (common colds) may lead to ear infections, especially in children.”

Dr. Truong recommends his patients give the flu vaccine to all 6 months or older children to prevent the infection.

The main villain in this story seems to be a lack of space because it allows bacteria and viruses to accumulate in the ears. Children are susceptible to this disease because their ear channels haven’t developed enough, and the space is tight.

The Mayo Clinic also points out adenoids as a major cause of ear infections. They sit near the back of the nose, and experts believe they take part in the immune system, which makes them vulnerable to swelling and infection.

The thing is, they are close to the Eustachian tubes, and when they swell, everything that’s around it suffers.

Following this logic, choosing the headphones carefully and not using them for extended periods might be a good idea. But worrying too much about preventing ear infections might be a waste of time, according to experts.

Richard Rosenfeld, a professor of otolaryngology at SUNY Downstate Medical Center in Brooklyn, N.Y., said in an interview with USA Today, “Hereditary factors cause about 70% of the risk of ear infections, so there is not always a lot that can be done to prevent them.”

The best option is to vaccinate and seek medical attention if the symptoms last more than a day.

The human body is equipped to deal with this kind of problem independently. However, some cases need medical attention and can result in severe hearing problems and other issues. Luckily, the signs are easy to see. You should see a doctor if:

  • Symptoms last over 24 hours
  • The affected is a child 6 months or younger
  • The earache is too strong
  • You can see pus, blood, or fluids coming out of the ear

Can Numb Toes Be a Symptom of an Ear Infection?

Numb toes can indeed be a symptom of an ear infection. While it may not seem connected, certain infections, such as mastoiditis, can spread to the nearby nerves, causing numbness in distant areas like the toes. If you experience this, seeking medical attention is crucial as it can help determine the underlying causes and treatment of numb toes.

Ear Infection Treatments: The Right Way To Deal With It

Ear Infections are a common enough occurrence that learning to treat them becomes relevant. To be specific, ear infections are a lot more likely to be affected by children. This goes far back, all the way to before they even begin going to school.

Of course, it’s often not something one would worry about until it is there. However, parents should be able to identify the symptoms of ear infections and treat them in their children.

If only because, according to Healthline, ear infections tend to become chronic. Which can cause permanent damage to one’s hearing.

Listed below are the most common ear infection treatments available.

Be careful before you recur to antibiotics.

Most people like to self-medicate, especially parents. When they see their children in pain, they want a quick solution. However, the symptoms alone are not enough to make an accurate diagnosis.

Ear infections are easy to spot because it might look like a ‘pop-able pimple’ on the eardrum. However, that is not something you will check on your own; you’ll need a doctor.

What’s the next step when an ear infection has been confirmed?

To the frustration of the worried parents, many doctors might choose to “watch and wait” because antibiotics are unnecessary most of the time. According to the National Prescribing Service:

“Parents should not be concerned if the doctor does not prescribe antibiotics or suggests they wait and see what happens before having a script dispensed,” stated a 2009 press release from the NPS. This Australian government-funded organization aims to help people use medicines wisely.

If it’s not a mild case, most physicians will prescribe pain medicine, such as acetaminophen and ibuprofen, so that the person can sleep well while the antibiotics take effect. The treatment can last a couple of weeks, depending on whether the patient is a child or an adult.

Some studies don’t approve of the “watch and wait” method because of the complications of not treating ear infections on time. However, the Centers for Disease Control and Prevention (CDC) also says antibiotics are often inadequate.

Are there extreme cases of ear infections?

Ear infections are mainly caused by the accumulation of bacteria and fluid in the middle ear. The resulting inflammation handles the pain and headaches. If the medicine is not working, it might be because of anatomy.

Some people’s ear cavities don’t allow for a free discharge of fluids, which means bacteria always accumulates.

These rare cases, according to WebMD, are almost only limited to children, and doctors might suggest implanting ear tubes through surgery. The latter creates an exit route for liquids, common in persistent middle-ear fluid cases.

To summarize, the solution to ear infections is not always powerful medicine. No one enjoys watching their children in pain or is in pain, but if you want to get rid of the problem, follow your doctor’s advice.
