Understanding the Different Causes of Sinusitis

As beautiful as spring and summer are, they have a knack for bringing out our allergies. From the pollen floating through the air to the dust and pet dander that falls onto our skin, our sinuses are vulnerable to so many things.

Our caring staff at Florida Ear Nose Throat & Facial Plastic Surgery Center is led by Wade Han, MD FACS, and Elvira Livigni-De Armas, Au.D. Along with our compassionate team of professionals, they treat our patients who are dealing with sinusitis with tender care. 

If you think you may have sinusitis, find out more about it below, including its most common causes.

What is sinusitis?

Sinusitis refers to inflammation of the mucus-lined membranes inside your nose and head. When the tissues swell, the opening of your sinuses is blocked. This causes a buildup of mucus and can cause an infection. 

Sinusitis is uncomfortable and can start with a stuffy nose that refuses to get better with treatment. It is also possible to have chronic sinusitis. This is when your sinusitis lasts for three months or longer. 

What causes sinusitis?

According to the CDC, having had a recent cold and inhaling secondhand smoke are risk factors for developing sinusitis. Seasonal allergies and weak immune systems also increase your risk of developing sinusitis. Having sinus issues, like polyps or a deviated septum, could also make you more vulnerable to this condition. 

Sinusitis is most likely to be experienced by allergy sufferers and has several actual causes:


Viruses are the primary cause of sinusitis. Viral infections last for up to one month and are characterized by the aforementioned swelling and mucus. 


Less often, bacteria are responsible for sinus infections. When this happens, the infections tend to last longer than 10 days, whereas viral infections will usually go away on their own within 10 days. 


Year-round allergy sufferers are always at risk for developing sinusitis. Contact with respiratory allergens, whether they are animal dander, pollen, or pollution can trigger an allergy cold, as well as sinusitis.  

How do I know I have sinusitis?

It’s difficult to miss a stuffy nose that doesn’t go away, but some people have been living with sinusitis for so long, they’ve accepted their condition as normal. Common signs of sinusitis include:
