Sinusitis

Sinus infection happens when fluid builds up in the sinuses (air-filled pockets in the face), promoting the growth of germs. It is most commonly caused by a cold and can also be caused by allergies. Symptoms include facial pressure, fever, nasal congestion, and postnasal drip.

How It Works

Sinusitis is inflammation of the sinuses, the air-filled spaces behind your forehead, cheeks, nose, and between your eyes. It can be acute (short-term) or chronic (lasting 12+ weeks).

TYPES:

•Acute sinusitis: Usually from viral cold; lasts <4 weeks
•Subacute sinusitis: 4-12 weeks
•Chronic sinusitis: >12 weeks; often with polyps
•Recurrent acute: 4+ episodes per year

SYMPTOMS:

•Facial pain/pressure (worse bending forward)
•Nasal congestion and discharge
•Reduced sense of smell
•Post-nasal drip
•Headache
•Fever (acute bacterial)

CAUSES:

•Viral infection (most common)
•Bacterial infection (complicating viral)
•Allergies
•Nasal polyps
•Deviated septum
•Fungal (rare)

WHEN TO SEE A DOCTOR:

•Symptoms >10 days without improvement
•High fever (>102°F/39°C)
•Severe headache or facial pain
•Visual changes
•Symptoms that worsen after initial improvement

FIRST-LINE TREATMENTS:

•Saline irrigation: Most important; flushes sinuses
•Intranasal corticosteroids: Reduce inflammation
•Decongestants: Short-term only (3-5 days)
•Antibiotics: Only if bacterial infection suspected

* NAC helps thin mucus for better drainage.

* Serrapeptase and bromelain may reduce inflammation.

* Immune support with vitamin C and zinc.

Expected timeline: Acute sinusitis usually resolves in 7-10 days. Supplements may help with symptom relief and recovery.
