Sinus Infection

A sinus infection can make you feel tired, congested and miserable. Whether it's a short cold that comes and goes or a problem that keeps coming back, knowing what causes sinus infections and how to treat or prevent them is important for feeling better in the long run.

What is a Sinus Infection?

A sinus infection occurs when the tissue inside your sinuses becomes swollen or inflamed. Your sinuses are small, air-filled spaces located behind your forehead, cheeks and eyes. When these spaces get blocked, it can lead to a buildup of fluid, resulting in pressure, pain and discomfort.

Sinus infections can occur due to various reasons like viruses, bacteria or even fungi. Sometimes, they occur due to allergies or things in your environment that irritate your sinuses.

Types of Sinus Infections

Sinus infections are categorised based on their duration and frequency of occurrence. This classification enables doctors to determine the best course of treatment and helps patients better understand the nature of their condition.

Acute sinusitis

It is the most common type. It usually lasts for less than four weeks and follows a cold or a viral respiratory infection. Symptoms like nasal congestion, facial pain or pressure and thick nasal discharge come on suddenly and may resolve on their own or with minimal treatment.

Subacute sinusitis

It lasts for four to twelve weeks. It develops when an acute sinus infection does not fully heal or when allergies trigger ongoing inflammation. The symptoms are similar to acute sinusitis but may linger or fluctuate in intensity. Treatment may include medications like decongestants, nasal corticosteroids or further evaluation for any contributing factors.

Chronic sinusitis

It is diagnosed when symptoms last for more than twelve weeks after the treatment. Unlike acute sinusitis, the symptoms of chronic sinusitis may be less intense but longer-lasting. People who experience constant nasal stuffiness, facial pressure, a reduced sense of smell and postnasal drip. This condition is caused by ongoing inflammation rather than infection and it may be associated with nasal polyps, allergies or structural issues such as a deviated septum.

Recurrent sinusitis

It refers to multiple episodes of acute sinus infections, typically four or more times within a year. Each episode resolves, but the infections keep returning. This pattern may indicate a serious issue such as allergies, immune deficiencies or nasal blockages. Treating recurrent sinusitis involves addressing both the acute symptoms and any root causes to prevent future flare-ups.
