Sinus Infections and Asthma


How Is Sinobronchial Syndrome Related to Asthma?

Sinobronchial syndrome is a combination of sinusitis and the resulting lower respiratory tract symptoms such as bronchitis or asthma. With sinobronchial syndrome, the sinus disease may be caused by allergies or an infection -- or it can be chronic. The lung disease can be one of several types such as acute infective bronchitis, recurrent bouts of bronchitis, chronic bronchitis, or asthma that's difficult to manage.

It's thought that the sinus disease resulting in lower airway symptoms such as asthma is due to a constant drip of inflammatory and infective secretions from the back of the nose to the back of the throat. This throat irritation may cause bronchial constriction by a reflex transmitted by the nervous system. Or, the postnasal drip of inflammatory secretions from the upper airway may create a secondary inflammatory reaction of the lungs, causing either asthma or bronchitis.

What Are the Symptoms of Sinobronchial Syndrome?

With sinobronchial syndrome, you will feel a host of miserable nasal and chest symptoms including shortness of breath, wheezing, a productive cough, nasal obstruction, fever, headache, or chest tightness. Along with signs of sinus inflammation or infection with pain and tenderness over the sinuses, you might have constant nasal and sinus drainage, wheezing, cough, and other respiratory or asthma symptoms.

How Can You Prevent Sinusitis?

There's no sure-fire way of preventing sinusitis. But there are some things you can do to lower your risk:

  • Use regular steroid sprays to prevent further sinus infections. This is particularly important if you've had recurrent or chronic sinusitis.
  • Avoid allergens and irritants, if you have allergies.
  • Take your asthma medication as recommended. Keeping your asthma symptoms under control can reduce your risks of developing serious sinusitis.
