Sinusitis: Causes, Symptoms, Prevention, and Treatment

Sinusitis is such a common pathology that most people have had it at some time throughout their lives. A simple flu or a badly cured cold are mainly the reasons that usually trigger a picture of sinusitis.

Not giving enough importance to the symptoms that it presents can lead to chronic sinusitis over time, so it is advisable to know how to prevent and treat sinusitis.

What Is Sinusitis

The paranasal sinuses are cavities that are found in the surrounding bones and that are connected by ducts and holes to the nasal cavity. These cavities are formed by mucosa, and its main function is to help humidify and heat the air that enters through the nose. 

When the mucous membranes become inflamed as a consequence of a cold, for example, they make mucus, resulting in an increase in secretion. When the mucous membranes found in the paranasal sinuses become inflamed, the cavities become covered, clogging and inflaming, sometimes leading to the proliferation of bacteria.

Why Is Sinusitis Due To, Causes Of Sinusitis

Do we know what causes sinusitis, and what are the factors that cause it?

The most common causes of sinusitis are colds and flu, although these are not the only factors.

Many of the badly cured colds often lead to sinusitis, and I feel this, along with the flu the most common cause of sinusitis. The accumulation of mucus and the obstruction of the nostrils lead to an inflammation of the sinuses, leading to inflammation of the mucosa.

Another cause of sinusitis is an allergy, which is usually a factor that predisposes people who suffer from it to present symptoms of sinusitis. What happens in the case of rhinitis is that the mucosa of the nose becomes inflamed, and the paranasal sinuses produce mucus, which reaches through the ducts to the nostrils. When these ducts are blocked as in the case of rhinitis, then the mucus begins to accumulate, it becomes infected and ends up producing a picture of sinusitis.

There are other factors that are less often the cause of sinusitis, such as irritating factors (such as tobacco), chlorine in swimming pool water, air conditioners, sudden changes in atmospheric pressure, such as flying or driving or even have a weak immune system.

Symptoms Of Sinusitis

In general, the symptoms of sinusitis are often confused with those of a common cold or a cold, since these are usually the same: discharge, nasal congestion, headache, pressure sensation behind the eyes, cough, which usually worsens at night and in some cases fever.

The difference between sinusitis and a cold will depend on the picture presented by the patient in terms of the duration over time of the pathology. Normally those colds that last more than seven or ten days end up presenting a picture of sinusitis.

In the case of acute sinusitis, the symptoms are very similar to those of the cold, although they are usually accompanied by fever, purulent mucus, pain, and general malaise.
