Causes of otitis externa

Otitis externa is a disease caused by infection of our external auditory canal. This disease often occurs in summer because we swim frequently in summer, so infection will occur. This is a very serious disease. The harm caused by this disease to us is very terrible. Therefore, in order to better stay away from the harm of this disease, we must do a good job of prevention according to the cause of the disease in our daily life. So what is the cause of otitis externa? Let’s find out together.

Otitis externa is a disease that often occurs around us. This disease has no restrictions on population or age when it occurs. People of any age can be harmed by this disease, so we must pay attention to this disease and seek treatment as soon as possible when symptoms appear.

1. Lack of earwax: Because the earwax in the external auditory canal of normal people is slightly acidic and has anti-infection effects, when earwax is lacking, the external auditory canal loses its antibacterial acidic coat, making it easy to cause disease.

2. Systemic diseases: such as diabetes, endocrine disorders, chronic constipation and anemia can also easily induce this disease.

3. Trauma: Accidentally damaging the skin of the external auditory canal when picking your ears, or scratching the skin with foreign objects, can cause bacteria to enter the epidermis or even the dermis, causing infection.

4. Water immersion: After swimming or flushing the external auditory canal, if the inside of the ear is not wiped clean, the skin will be soaked and damaged, which can easily lead to infection.

5. Otitis externa: The stimulation of purulent secretions of acute and chronic suppurative otitis externa often leads to a decrease in the resistance of the skin of the external auditory canal.

6. Allergic reaction: The external auditory canal is secondarily infected based on the allergic reaction. For example, patients with external ear eczema are prone to otitis externa.

7. Changes in temperature and humidity: Rising temperature and increased humidity can often lead to changes in the chemical properties of earwax and blockage of the cerumen gland ducts, thereby reducing its defense capabilities.

This is the end of the explanation about the causes of otitis externa. There are many reasons in our lives that can lead to the occurrence of this disease, so we must be careful and cautious and do a good job of care in daily life. Correct care can reduce the chance of occurrence of this disease, but once we have this disease, we must not be anxious. As long as we actively receive treatment, this disease is still very easy to treat.
