S
inusitis, an inflammatory and infectious disease of the sinuses, is more and more frequent. Often recurring and chronic, it may follow a cold or flu but may also happen by itself.
Allergic reactions of the mucous membranes accompanied by polyps often contribute to the development of sinusitis. A humid and cold climate, significant temperature variations and high levels of air pollution (outside pollution, recycled air) promote the development of sinus infections. Milk products and food allergies add further to these precipitating factors.
