## Q&A

**Q: What is the main cause of everyday swollen legs and ankles (kaki bengkak)?**  
A: Everyday leg swelling (peripheral edema) is typically caused by gravity-induced fluid accumulation after prolonged standing or sitting, excessive dietary salt consumption, hormonal fluctuations during menstruation or pregnancy, and warm weather common in Malaysia's tropical climate.

**Q: When is swollen legs and ankles considered a medical emergency?**  
A: Seek immediate medical care if the swelling occurs suddenly, affects only one leg with localized warmth or calf pain (potential DVT), or is accompanied by chest pain, shortness of breath, dizziness, or coughing up blood.

**Q: How does the Malaysian tropical climate contribute to swollen feet and ankles?**  
A: High ambient temperatures cause peripheral blood vessels to dilate (vasodilation) to dissipate heat, allowing body fluids to pool in lower extremities via gravity, especially when combined with high-sodium local diets and dehydration.

**Q: What are the safest home remedies to reduce mild leg swelling?**  
A: Key non-medical remedies include elevating legs above heart level for 15–20 minutes, reducing processed salt intake, drinking adequate water to assist renal excretion, wearing compression socks if standing long hours, and avoiding tight footwear.

**Q: Can dietary supplements cure or treat leg swelling?**  
A: Dietary supplements cannot cure, treat, or replace medical therapies for underlying circulatory or organ conditions. While hydration and balanced micronutrients support overall fluid balance, any persistent or painful swelling must be evaluated by a healthcare professional.
