What Are the Types of Sinus Infections?
Sinus infections, also known as sinusitis, can be classified into four types based on their duration and cause. The most common types are acute sinusitis, subacute sinusitis, chronic sinusitis, and recurrent sinusitis. Acute sinusitis typically lasts less than 4 weeks and is usually triggered by a viral infection, often following a cold or respiratory infection. The symptoms may include a runny nose, nasal congestion, headache, facial pain, and pressure in the face. Subacute sinusitis lasts between 4 and 12 weeks and may result from a lingering viral infection or a bacterial infection. The symptoms are similar to acute sinusitis, but they persist for a longer period.
Chronic sinusitis lasts for more than 12 weeks and may be caused by ongoing inflammation, often due to factors like allergies, nasal polyps, or structural issues in the sinuses. It is more persistent and may require long-term treatment, including antibiotics, steroids, or nasal irrigation. Recurrent sinusitis refers to multiple episodes of acute sinusitis within a year, with each episode lasting several weeks. Identifying the type of sinus infection is crucial for determining the appropriate treatment. Acute infections often resolve with rest, fluids, and over-the-counter medications, while chronic sinusitis may need a more comprehensive approach, including specialized care.
