Sinusitis Types and Symptoms
Sinusitis is caused by inflammation or infection of one or all of the paranasal sinuses and is categorized into three types on the basis of the duration of the inflammation/infection.
Acute sinusitis usually lasts for no more than 3 weeks. It is often triggered by flu or a head cold and causes typical ‘cold’ symptoms, but lasts longer than a week.
Chronic sinusitis usually lasts for more than 3 weeks and can continue for months or even years. It is commonly caused by allergies or bacterial infections. Among people under the age of 45, chronic sinusitis is one of the most common chronic illnesses.
This is characterized by several separate attacks during the year. The attacks are usually caused by an allergic reaction to weather conditions or other environmental factors.
