Causes and Symptoms of a Sinus Infection
Sinus infection is a common ailment because more than 37 million Americans suffer from it each year. Sinuses are air cavities within the facial bones of the skull, covered by mucous membranes similar to those in other parts of the airways.
In these membranes, there are microscopic hair-like protrusions, called Cilia, which sweep back and forth every 10 seconds on average. This sweeping motion clears the mucus that is produced by the sinuses into the back of the nose and swallowed unconsciously by us.
Mucus is produced naturally by the sinuses to trap foreign particles, viruses, bacteria and other allergens from the air we breathe in before they enter the lungs. Normal mucus is thin, a little sticky and with a slippery feel.
If cilia function is impaired, viruses are allowed to stay longer in the nasal areas which then become an ideal home for them to multiply and proliferate. This results in the mucous membranes becoming inflamed and they produce thicker, sticky mucus.
The cilia are unable to perform its function to clear the sticky and heavy mucus. Nasal congestion results and the poor natural ventilation within the sinus passageways allow bacteria to proliferate. A bacterial infection takes place.
The benefit of maintaining healthy cilia function is that we could avoid unecessary suffering from illnesses such as the common cold, viral influenza and sinus infection.
Causes of sinus infection
1. As explained above, poor cilia function is a major cause of sinus infection
2. Abnormal anatomy of the nose. There are people who are borned with a deviated septum. The nasal septum is the wall dividing the nasal cavity into two halves. A deviated septum results in obstruction to normal airflow through the affected side of the nasal passage.
3. Nasal polyps. Sinus polyps are teardrop-shaped, non-cancerous growths on the lining of the nasal passages. The resultant nasal congestion can lead to a sinus infection.
4. Abnormally large inferior turbinates. Unfortunately, some people have large inferior turbinates. These can cause chronic nasal congestion especially when there is an allergy.
Sinus infection symptoms
1. Nasal congestion or blocked nose. This is the result of the mucosa being inflamed.
2. Sinus headache. Pain and discomfort in the areas of the affected sinuses. For example, pain in the areas around the cheek points to a maxillary sinus infection.
3. Sinus infection mucus. With an acute bacterial sinus infection, the mucus would be yellow to green color. A chronic sinus infection produces mucus which may not be colored but its texture would be thick and glue-like.
How to maintain the healthy state of our cilia?
1. Do not smoke. Smoking causes the cilia to become paralyzed and dysfunctional
2. Avoid getting the common cold and viral influenza. Sinus infections usually come after these illnesses. Each subsequent sinus infection causes more cilia to become damaged.
3. Perform nasal irrigation on a daily basis. Nasal irrigation should be adopted as early as possible so that nasal cleansing becomes a part of your routine.
For a mild sinus infection, adopting proven sinus infection home remedies should eradicate the problem without the need to visit a doctor. Learn more about sinus infection treatment by doctors.
