## Q&A
**Q: What is gegata (urticaria) and what does it look like?**
A: Gegata (urticaria or hives) presents as swollen, raised red or skin-toned welts (wheals) that cause intense itching. The lesions can vary in size and often change location or fade within 24 hours without leaving permanent marks.

**Q: Why do gegata symptoms feel worse at night (waktu malam)?**
A: Nocturnal hives flares are driven by natural circadian rhythms: anti-inflammatory cortisol levels drop in the evening, skin temperature increases, and trans-epidermal water loss rises, intensifying the perception of itchiness during rest.

**Q: What is the difference between acute and chronic hives?**
A: Acute hives resolve within six weeks and are usually linked to an identifiable trigger such as food, viral illness, or heat. Chronic hives persist beyond six weeks, often involve immune-mediated pathways, and require ongoing medical supervision.

**Q: How can mild hives be relieved at home?**
A: Soothe the skin using cold compresses, take cool showers, apply calamine lotion, and avoid tight, synthetic fabrics. Speak with a licensed pharmacist regarding non-sedating oral antihistamines for symptom control.

**Q: When is gegata considered a medical emergency?**
A: Gegata is a medical emergency if accompanied by signs of anaphylaxis, such as swelling of the lips, tongue, or throat (angioedema), difficulty breathing, chest tightness, or lightheadedness. Seek immediate emergency care if these occur.
