The short answer

What is semaglutide, and who is it for?

Semaglutide is a prescription GLP-1 medicine that reduces appetite and helps weight loss when combined with diet and activity. It is a medical treatment, not a cosmetic one, and is prescribed only to suitable patients after assessment of BMI, health conditions and medications.

At YAAN Clinic in Gangnam, Seoul, a doctor decides whether it is appropriate; it is not started for short visits without a follow-up plan.
