Allergic sinusitis, also known as allergic rhinosinusitis, is a condition where the sinuses become inflamed due to allergies.
Types of Allergic Sinusitis:
Acute Allergic Sinusitis:
Short-term inflammation of the sinuses due to allergies, often triggered by seasonal allergens like pollen.

Chronic Allergic Sinusitis
Persistent inflammation lasting more than 12 weeks, typically associated with ongoing exposure to allergens or underlying conditions.
Causes of Allergic Sinusitis:
Allergens: Pollen, dust mites, pet dander, mold spores, and certain foods can trigger allergic reactions leading to sinus inflammation.
Immune System Response: Allergens stimulate the immune system to release chemicals like histamine, causing sinus membranes to swell and produce excess mucus.
Environmental Factors: Air pollutants, tobacco smoke, and changes in weather can exacerbate symptoms.
Symptoms of Allergic Sinusitis
- Nasal Congestion: Blocked nose or difficulty breathing through the nose.
- Facial Pain or Pressure: Particularly around the cheeks, eyes, and forehead.
- Postnasal Drip: Mucus dripping down the throat.
- Headache: Often worsens with sinus pressure.
- Reduced Sense of Smell and Taste: Due to nasal congestion.
- Cough: Often worse at night or early morning.
Management of Allergic Sinusitis:
Allergen Avoidance:
Identify and minimize exposure to allergens through measures like using air purifiers, allergen-proof bedding, and keeping windows closed during high pollen seasons.
Medications:
- Antihistamines: Reduce allergic reactions and relieve symptoms like itching and sneezing.
- Nasal Corticosteroids: Reduce inflammation in the nasal passages.
- Decongestants: Provide temporary relief from nasal congestion.
- Saline Nasal Irrigation: Helps clear nasal passages and reduce symptoms.
- Lifestyle Adjustments.
- Cough: Often worse at night or early morning.
