Causes

Several types of source can cause rhinosinusitis. The problems can last only a short time, termed acute rhinosinusitis, or they can last for months of even years, called chronic rhinosinusitis.

Environmental

The environment contains extensive sources of nose and sinus irritants. Some of these can form biofilms, protective meshes that prevent the pathogens from being destroyed.

• Viruses.
• Bacteria.
• Molds.
• Allergens.
  • Dust.
  • Pollen.
  • Foods. Common food allergies that can induce rhinosinusitis include dairy, peanuts, tree nuts, wheat, and other grains. An elimination diet, in which the person eats a simple diet, can reveal possible allergens.
• Weather can cause serious sinus issues. In particular, extremely high or low humidity and extremely cold or hot weather can cause problems. Sudden changes in atmospheric pressure, such as before a storm, can also aggravate problems.

Biological

People are born with a set of genetic coding that can predispose the person towards rhinosinusitis. Additional biological developments throughout the course of life can cause sinus issues.

• Small or otherwise malformed sinuses or nose.
• Weak immune system.
• Polyps.
• Deviated septum.
