									What Causes Sinus Infection

Ever wondered what really causes a sinus infection? There are many
possibilities and it is sometimes hard to pinpoint which one is the
culprit. You could have gotten it while you are at work, out in the mall,
doing a certain activity or even at home so here are some of the known
causes of sinus infections.

Most sinus infections are caused by the common cold otherwise known as
viral influenza. This causes congestion in the nasal passages and
inhibits the drainage of the sinuses which is why it becomes inflamed.

When this happens, the nose   is filled with mucus caused by the
accumulation of white blood   cells in the lining of the nose. This makes
it difficult for the person   to smell or even breathe and the only way to
get rid of it is to blow it   out.

Generally a common flu stays a maximum for a period of one week. After
that we usually recover, but it leaves our sinuses inflamed. The nose is
a very sensitive part of our body which catches a viral infection very

Sinus infection can also be caused by exposure to dust particles, pollen
and other irritants in the air. If there is too much of this already in
the nasal passages, it prevents mucus from draining away. When these
bacteria such as streptococcus pneumoniae and haemophilus influenzae end
up in our upper respiratory tract and multiply, then it causes us to have
a sinus infection.

You can come into contact with these every time you go outdoors or when
you are inside the house especially in places where natural sunlight
cannot reach. Another example is the fungus known as aspergillus that can
cause problems to the immune system.

If you have asthma, you are a high risk for sinus infections because your
nasal polyps inside your nose are swollen. This results in chronic sinus
infections that could last for 2 weeks.

Lack of water also causes a sinus infection. This is because the mucus
will thicken making it difficult for the cilia to move it through the

Sinus infections can also happen whenever we are stressed. To prove the
point, one such condition known as vasomotor rhinitis shows that stress
does cause excessive swelling and mucus production.

You can also get a sinus infection by blowing your nose too much. This is
because your nose will swell after blowing it too hard or too much.

Certain activities that are fun can also cause sinus infection. Traveling
by air and scuba diving are very common because to much pressure in the
sinuses causes bacteria to grow.
If you don’t watch your kids carefully, they may inhale harmful
substances or other foreign objects that introduce bacteria into the

Certain medications are also known to cause sinus infections as a side
effect because it may affect the functioning of the mucus membrane.

Lastly, although very rare, you can get a sinus infection from disease
teeth because the maxillary sinus in the cheekbone becomes infected by
the root of a diseased upper tooth.

There are many causes of sinus infections and it is not only bacterial or
viral. Now that you know what these are, it is time for you to take steps
to prevent this from happening.
