Sinusitis
Simply put, sinusitis is inflammation of
lining of your sinuses.
Sinuses
The sinuses are located behind
eyes,
cheeks, and
jaw. They are chambers in which mucous is produced to clean out
bacteria that we take in every day through
mouth and nose. The mucous moves along
cilia, which are tiny, moving hairs that maneuver
mucous. Sinusitis creates difficulties for
sinuses as they try to do their job, because
cilia cease to move and
sinuses either produce too much mucous or too little.
Possible Causes
Sinusitis can be caused in a variety of ways. The inflammation of
sinus lining is sensitive to changes in temperature or humidity, and often swimming, diving, extreme changes in temperature, and smoking will set off inflammation. The reason these things can cause sinusitis is that they create a friendly environment for bacteria and viruses.
For example, smoking paralyzes
cilia, causing
sinuses to think that there are bacteria or a virus and to produce more mucous. Since
cilia cannot move,
mucous just sits there, congests, and becomes a breeding ground for more bacteria, creating a sinus infection. Stagnant water or liquid buildup from water activities can produce similar effects. Or, if a virus has already infected
sinuses and swelling occurs, then
produced mucous will build up even more. Sinusitis is just
beginning of any nasal problem.
What many people don’t know is that sinusitis, though beginning in
sinuses can also contribute to an ear infection. The reason is that
sinuses and
ears are connected through
Eustachian tube, and something as simple as sneezing can push infection right out to
ears. Not only can infection move out to
ears but also down to
lungs. Sinusitis is not entirely unrelated to an upper respiratory infection. Often Sinusitis, ear infection, and upper respiratory infection have similar, if not
same, causes.
