Sinus Infection (Sinusitis)

Get information on sinus infections and schedule a consultation with an Easy Pharmacy online pharmacist for personalized treatment and prescription advice.

Overview

Sinusitis, or a sinus infection, occurs when the lining of the sinuses becomes inflamed or swollen. This inflammation hinders proper mucus drainage, leading to congestion, nasal blockage, and facial discomfort.

Types of Sinusitis

Sinus infections are categorized into three main types:

Acute Sinusitis

Acute sinusitis is often caused by viral infections, such as the common cold, and can sometimes result from bacterial infections. It usually resolves on its own within a few weeks.

Chronic Sinusitis

Sinusitis is considered chronic when it lasts for more than 12 weeks despite treatment. Common causes include nasal polyps, a deviated septum, allergies, or other underlying health conditions.

Recurrent Sinusitis

Recurrent sinusitis occurs when multiple episodes of acute sinusitis happen within a year. It can be triggered by allergies, structural nasal issues, or immune system disorders.

Causes of Sinus Infections

Several factors can contribute to sinus infections, including:

Viral infections – The most common cause of acute sinusitis, typically resulting from colds or the flu.
Bacterial infections – Often develop after a viral infection, especially in individuals with weakened immune systems.
Allergies – Can cause inflammation and block sinus drainage.
Nasal polyps – Growths in the nasal passages that obstruct airflow.
Structural abnormalities – Conditions like a deviated septum, nasal bone spurs, or narrow sinus openings can lead to sinus blockages.
Weakened immune system – Diseases such as HIV/AIDS, diabetes, or autoimmune disorders can increase susceptibility to infections.
Environmental factors – Exposure to air pollution, cigarette smoke, dry air, or sudden atmospheric pressure changes can irritate the sinuses.
Water exposure – Activities like swimming or diving can introduce water into the sinuses, leading to infections.
Upper respiratory conditions – Infections such as adenoiditis or tonsillitis can spread to the sinuses, worsening inflammation.

Symptoms of Sinusitis

Common symptoms of a sinus infection include:

Facial pain and pressure – Discomfort, throbbing, or pressure around the eyes, forehead, or cheeks.
Nasal congestion – A blocked nose making breathing difficult.
Thick nasal discharge – Yellow or green mucus from the nose.
Loss of smell or taste – A reduced or absent sense of smell or taste.
Persistent cough – Often worse at night.
Fatigue – Feeling generally tired or sluggish.
Fever – An elevated body temperature in some cases.
Bad breath (halitosis) – Often due to mouth breathing.
Headaches – Caused by sinus pressure.
Tooth pain – Discomfort in the teeth due to sinus pressure.

Treatment for Sinusitis

For Mild Sinus Infections

Get plenty of rest.
Stay hydrated by drinking enough water.
Keep indoor air moist with a humidifier.
Use a saline rinse to clear nasal passages.
Take over-the-counter pain relievers like Paracetamol or NSAIDs (e.g., Ibuprofen). (Avoid aspirin in children under 16 due to the risk of Reye’s syndrome.)

Avoid allergy triggers like cigarette smoke and air pollution.

For More Severe Sinus Infections

Use nasal decongestant sprays (limit use to avoid dependency).
Take allergy medications or undergo immunotherapy for allergy-related sinusitis.

Consider Functional Endoscopic Sinus Surgery (FESS) if sinusitis persists beyond three months and doesn’t respond to treatment, particularly if structural abnormalities are present.
