Sinusitis is one of the most common medical conditions seen in the community setting. Sinusitis may be caused by either a viral or bacterial infection, or by an allergy. About 0.5% of all upper respiratory tract infections, such as colds, are complicated by sinusitis.
Healthy sinuses are filled with air. However, when someone has a sinus infection, one or more of the sinuses become inflamed and fluids build up in the sinuses, causing sinus congestion and runny nose.
This module will help you to understand what sinusitis is, what the most common causes, symptoms and risk factors are and how best it can be managed with appropriate over-the-counter medications and other home treatments. The different types of sinusitis are explained as well as when patients should be referred to a doctor.
