What causes otitis media?

Update Date: 2024-07-29 Source: Network

Otitis media is caused by upper respiratory tract infection, allergic reaction, ear trauma, immune system abnormalities, and unhealthy living habits.

Reasons for Otitis Media:

1. Upper respiratory tract infection: Upper respiratory tract infection is the main cause of otitis media. Common pathogens include Streptococcus, Streptococcus pneumoniae, and Haemophilus influenzae. These bacteria or viruses enter the middle ear through the Eustachian tube, causing infection and leading to otitis media.

2. Allergic reaction: Allergic reactions can also lead to otitis media. Some people are allergic to specific environmental stimuli or foods, and the allergic reaction may cause the Eustachian tube to swell, blocking air circulation, providing a breeding ground for bacteria or viruses, which then triggers otitis media.

3. Ear trauma: Ear trauma is also an important factor in inducing otitis media. For example, excessive or improper use of cotton swabs to clean the ears may damage the eardrum, making it easier for viruses or bacteria to invade the middle ear.

4. Immune system abnormalities: Abnormalities in the immune system may also increase the risk of otitis media. For example, people with weakened immune systems, such as patients with HIV/AIDS, diabetes, or those who have long-term use of immunosuppressants, are more vulnerable to bacterial or viral infections, leading to otitis media.

5. Unhealthy living habits: Habits such as smoking and alcohol consumption may also increase the risk of otitis media. Nicotine and alcohol can stimulate the eardrum and middle ear mucosa, causing inflammation.

Otitis media is a common ear disease. Patients with otitis media should follow the doctor's instructions for medication and should not stop or change medication without permission to avoid aggravating the condition.
