What are the causes of catarrhal otitis media?

Generally speaking, catarrhal otitis media is secretory otitis media. The main manifestation of this disease is non-suppurative inflammation, which threatens the health of the ear. There are many causes of this disease, such as respiratory and nasal diseases, excessive fatigue, etc.

1. Respiratory tract and nasopharyngeal diseases. Such as colds, rhinitis, pharyngitis and so on. Because the middle ear is connected to the nose and pharyngeal tube, when there are a large number of bacteria in the nasopharynx, these pathogens can easily enter the ear. Therefore, when your baby has a cold, pay special attention to whether there are any abnormalities in his ears.

2. Swimming. When swimming, water will enter the ear from the external auditory canal, but if there is no hole in the eardrum, water will not enter the middle ear from the external ear. However, if there are many people in the swimming pool and cleaning is not done well, the bacteria or disinfectants in the water will enter the child's body through the nose and mouth, causing a cold and then otitis media.

3. Drink milk while lying down. A research report from the United States stated that when babies lie flat on their backs to drink water or milk, the water or milk will flow into the nasopharynx, posing a risk of causing otitis media. Therefore, when your baby drinks milk or other beverages, keep his head higher and wipe off the water or milk that flows out at any time.

4. Fatigue. Lack of sleep or excessive physical exertion are the main causes of decreased immunity. A regular life, a balanced diet and adequate exercise are very important for maintaining health. So, don't let your child play too hard, and make sure he gets enough rest.

5. Smoking. European research reports show that having someone smoking at home can easily induce otitis media. Even if you drive the smoker to the balcony to smoke, his hair and clothes will be stained with harmful substances from cigarettes. When he holds the baby again, these harmful substances will be adsorbed on the baby's nasopharyngeal mucosa, easily causing inflammation.
