At your first GLP-1 appointment, a physician checks your BMI, blood pressure, and medical history, then orders baseline blood tests including HbA1c, fasting glucose, kidney function, liver enzymes, and thyroid function. If you are eligible, you leave with a prescription and a dose titration plan. In Phuket, this can all happen in a single walk-in visit with no referral needed.
You have been living in Chalong for six months, your weight has been creeping up, and a friend mentioned semaglutide. Or you are on a longer stay in Bang Tao and you want to know whether you can actually start this here, without waiting until you get home and navigating a GP referral system you are not even sure applies to you.
The answer is yes. A physician can assess your eligibility, run the blood tests the same day, and write a prescription on the spot if you qualify. What you need to know first is what that first GLP-1 appointment looks like, what the doctor is checking for, and what happens after you leave.

What to Bring to Your First GLP-1 Appointment
You do not need a full medical file. What helps is a clear picture of your current health. Bring any recent blood test results you have, even a photo on your phone. If you take regular medications, list them by generic name rather than brand name, because names differ between countries. A rough note of any home-country diagnoses saves time.
If you have no records at all, that is workable. The physician takes a full verbal history and orders baseline blood tests the same day. A photographed prescription or a brief summary letter from a doctor at home is useful but not essential. Bring a list of any supplements you take too. Some affect blood sugar management and matter to the prescription decision.
You can find a more detailed checklist at the what to bring to your first GLP-1 appointment page if you want to prepare ahead.
Who Is and Who Is Not a Candidate for GLP-1 Therapy
GLP-1 medications such as semaglutide and tirzepatide are approved for adults with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related condition such as type 2 diabetes, high blood pressure, or high cholesterol. These thresholds come from current prescribing guidelines.
There are also hard contraindications. A personal or family history of medullary thyroid carcinoma, or of multiple endocrine neoplasia type 2, rules them out. Active pancreatitis is a reason to stop the medication and seek care immediately. A history of pancreatitis is not a listed contraindication in the FDA prescribing information, but it is a reason for caution that the physician will weigh carefully before prescribing. Pregnancy and breastfeeding are exclusions too. The physician will ask about all of these directly, not as a formality, but because they change the prescription decision entirely.

What the Doctor Checks at Your First Appointment
The consultation covers more than your weight. The physician measures your BMI and blood pressure, and asks about your cardiac history, kidney and liver health, and any history of thyroid or pancreatic disease. This is how they determine whether GLP-1 therapy is safe for you specifically, not for the average patient.
The baseline blood panel before your first prescription typically includes HbA1c, fasting glucose, kidney function markers such as creatinine and eGFR, liver enzymes ALT and AST, a lipid panel, and TSH for thyroid function. These can all be processed at Takecare Clinic Phuket on the same day as your consultation. Most results come back within 24 hours. If you want fasting glucose and lipid results on the same visit, plan not to eat for several hours beforehand. HbA1c does not require fasting.
GLP-1 Medications in Thailand: What You Need to Know in 2026
Since 2026, the Thai FDA classifies GLP-1 weight-loss pens as prescription-only. You cannot buy semaglutide or tirzepatide over the counter at a Phuket pharmacy, and purchasing through unverified online sources carries genuine risk. Products sold informally may be counterfeit, incorrectly stored, or mislabelled. A valid prescription from a licensed physician is the only compliant route.
If you arrived in Phuket already using a GLP-1 medication prescribed abroad, carry the original prescription or packaging. This matters if you need a prescription refill in Phuket while you are here, which the clinic can assist with through a short consultation.
Your First GLP-1 Appointment in Phuket: How It Actually Works
Most GLP-1 guidance assumes you have a home GP, a referral letter, and health insurance with prior authorisation. None of that applies in Phuket. There is no GP referral system. You walk in, see an English-speaking doctor, and the visit covers history, examination, blood tests, and prescription in a single consultation.
For expats in Cherng Talay, Rawai, or Laguna without a regular local doctor, this is the practical route. For tourists on a longer stay, the same applies. At Takecare Clinic Phuket, the physician who sees you is the one who reviews your results and confirms your prescription. You do not get passed between departments or asked to call back tomorrow.
The Dose Titration Plan Your Doctor Sets Before You Leave
GLP-1 medications start at a low dose. This is intentional. The titration schedule builds slowly to reduce nausea and other early side effects. Your physician will outline the exact schedule based on which medication is prescribed and which formulation is available.
Before you leave the consultation, you should have a written plan: the starting dose, when to increase it, what side effects to watch for at each step, and when to return or contact the clinic. If you are leaving Phuket before the first dose increase point, the physician can write a summary letter for your doctor at home. Telemedicine in Phuket is available as a bridge between leaving the island and your next in-person appointment.
Managing Side Effects in the First Few Weeks
Nausea is the most common early side effect, and it tends to be worst in the first one to two weeks at each new dose. It usually settles as your body adjusts. Smaller meals, avoiding fatty food, and not lying down right after eating helps most people. Phuket’s heat adds something worth noting: dehydration makes nausea worse, so staying on top of fluids matters more here than it might at home.
Other early effects include loose stools or constipation, mild fatigue, and occasional injection site reactions. What warrants a call or a return visit is persistent vomiting that stops you keeping fluids down, severe abdominal pain that does not ease, or any sign of an allergic reaction. If side effects concern you between scheduled follow-ups, Takecare Clinic Phuket is available without a pre-booked appointment.
What the Follow-Up Appointment Covers
The first follow-up is typically four to six weeks after starting. The physician rechecks your weight, blood pressure, and how you have tolerated the medication. Based on this, they make the dose escalation decision: go up, hold, or step back.
Repeat blood tests at follow-up depend on your baseline results and any new symptoms. For patients with diabetes or borderline kidney function, monitoring is closer. For expats in Phuket without an ongoing GP relationship, building this into your routine at the clinic is more practical than flying home for each check-in. A routine health check-up in Phuket can run alongside your GLP-1 review at the same appointment.
