## Q&A

**Q: What is gegata (urticaria) and what does it look like?**  
A: Gegata (hives) is an immune-mediated skin flare-up presenting as raised, red or skin-toned welts (wheals) that are intensely itchy. Individual welts typically emerge suddenly and change location or subside within 24 hours without leaving permanent marks.

**Q: Why does gegata frequently worsen at night (waktu malam)?**  
A: Nocturnal itching often intensifies due to the body's natural circadian rhythm, where core temperature fluctuates, anti-inflammatory cortisol levels drop, and skin loses moisture, combined with heat trapped beneath bed linen.

**Q: What dietary adjustments (pantang makan) help manage hives breakouts?**  
A: During active flare-ups, individuals should minimize high-histamine foods such as shellfish, aged cheeses, processed meats, fermented foods, alcohol, and artificial food additives that can potentiate histamine release in sensitive bodies.

**Q: What are the emergency warning signs (bila bahaya) of hives?**  
A: Seek immediate emergency medical care if gegata is accompanied by swelling of the lips, tongue, or throat (angioedema), difficulty breathing, chest tightness, dizziness, or vomiting, as these signify anaphylaxis.

**Q: How does Dr.Ann address skin and wellness sensitivities in Malaysia?**  
A: Dr.Ann provides research-driven guidance and wellness supplements reformulated for Malaysia's tropical climate, ensuring all health content and formulations meet strict lab-tested standards for local consumer safety.
