FAQ
Honest answers to the questions you're actually asking.
Can I combine this with other treatments at Siam Clinic?
Yes many of our weight loss patients also use IV therapy, skin treatments, or peptide therapy at Siam Clinic. Because we share medical records across the group, your physician can coordinate care to avoid conflicts and sequence treatments appropriately.
How is this different from buying GLP-1 online or from another clinic?
Three differences: medical oversight (monthly physician review, not a one-time script), traceable medication (we dispense from licensed pharmacy supply, not online sources of questionable provenance), and integrated care (labs, body composition, nutrition built into the program). Buying online without supervision can work for some people but the safety margin is thin, and relapse rates are higher without structured follow-up.
I'm only in Phuket part-time. Can I still enroll?
Yes we treat many patients who split time between Phuket and overseas. The induction and body composition scans need to be in-person, but monthly reviews can alternate between in-clinic and video consultation. We'll work out a realistic cadence at your first consultation based on your travel pattern.
Is GLP-1 (Semaglutide/Tirzepatide) safe and legal in Thailand?
Yes. Both Semaglutide and Tirzepatide are registered prescription medications in Thailand, legally dispensed under physician supervision. We source only from licensed distributors with traceable batch numbers, and every prescription is preceded by a medical assessment. If a clinic offers GLP-1 without a proper medical work-up, that's a warning sign.
What are the side effects? Should I be worried?
The most common side effects of GLP-1 medications are gastrointestinal nausea, reduced appetite, occasional fatigue during dose changes. These are usually mild and manageable with correct titration, which is why monthly physician reviews matter. Serious side effects exist but are rare. Your doctor will review your full history and screen for contraindications before prescribing.
Will I gain the weight back when I stop?
This is the real question and the honest answer is: maintenance requires ongoing attention. Our programs include a structured taper rather than a hard stop, plus a nutrition and activity protocol specifically designed for the post-medication phase. Research shows patients who taper under supervision and maintain lifestyle changes retain the majority of their loss. Our data reflects the same.
