What Can Cause Nasal Congestion

Nasal congestion (or as many of us know it, a stuffy nose) can have several causes. Especially if there are more serious issues present, it’s important to have an idea of what might be causing your congestion. Discover what can cause nasal congestion ahead.


The most common cause of nasal congestion tends to be allergies. This is especially the case if you have seasonal allergies from pollen, dust, mold, and other irritants. Since nasal congestion is a symptom of allergies, take medicine such as Zyrtec or Claritin for treatment.

Nasal Polyps

Another reason why you might be suffering from nasal congestion could be due to nasal polyps. This cause is more of a serious one because the condition is a non-cancerous tumor that grows within the lining of the nose or sinus.

Sinus Infection

A sinus infection can lead to nasal congestion as well. Per the American College of Allergy, Asthma, and Immunology, 31 million people in the United States alone suffer from sinus infections. If you have a sinus infection, you might start to have congestion issues due to fluid buildup in your sinuses, which can lead to the development of bacteria, viruses, or fungus.

Common Cold

Your nasal congestion could also be the result of the common cold, otherwise known as viral rhinitis. A cold can last anywhere from a few days to a week, but symptoms can lead to bronchitis or asthma. In addition to nasal congestion, you might be suffering from a sore throat, a runny nose, or sneezing.

Other Nasal Congestion Causes

There are some other causes of nasal congestion that you should be aware of. These causes include the following:

  • Flu
  • Enlarged adenoids
  • Irritants
  • Pregnancy
  • Medications
  • Temperature or humidity changes
  • Supplemental oxygen use
