## Q&A

**Q: What is resdung in modern medical terminology?**  
A: Resdung is the Malaysian local term for allergic rhinitis and chronic rhinosinusitis—an IgE-mediated inflammatory reaction of the nasal mucosal lining caused by allergens rather than infectious bacteria or viruses.

**Q: What are the most common triggers of resdung in Malaysia?**  
A: Major triggers include house dust mites (*Dermatophagoides pteronyssinus*), high indoor humidity fostering mold spores, sudden temperature shifts from outdoor heat to indoor air conditioning, vehicle exhaust haze, and pet dander.

**Q: How does resdung differ fundamentally from the common cold?**  
A: Resdung causes chronic watery nasal discharge, intense itchiness, and sneezing without fever, lasting weeks to months. The common cold (selsema) is viral, typically resolving in 7–10 days with thick mucus and mild fever.

**Q: What over-the-counter (OTC) pharmacy remedies are commonly used for resdung?**  
A: Standard pharmacy options include non-drowsy second-generation oral antihistamines (e.g., cetirizine, loratadine), intranasal corticosteroid sprays for inflammation, and sterile saline nasal irrigation kits. Always consult a licensed pharmacist before use.

**Q: What non-pharmacological steps help control resdung flare-ups at home?**  
A: Wash bed linens weekly in hot water above 55°C, use HEPA air purifiers, maintain indoor relative humidity around 50%, practice daily saline nasal rinses, and support baseline immune health with balanced nutrition and hydration.
