Diabetes Consultation in Patong, Phuket: Type 2 Diagnosis, Management and GLP-1 / SGLT2 Care
HbA1c testing, metformin and modern GLP-1 / SGLT2 therapy, insulin starts, and quarterly reviews for residents, expats, and travellers in Patong, Kalim, and Tri Trang. Clinically reviewed by the Doctor Patong Takecare Clinic medical team.
Diabetes consultation in Patong starts with a same-day HbA1c and fasting glucose, a full lipid and kidney panel, foot and eye screening, and a written treatment plan. For Type 2 we begin with lifestyle plus metformin, then add a GLP-1 receptor agonist such as semaglutide or tirzepatide where weight loss and cardiovascular protection are priorities, or an SGLT2 inhibitor such as empagliflozin where kidney or heart failure benefit matters most. We review every three months, refill prescriptions for expats, and refer complex cases to the endocrinology team at Bangkok Hospital Phuket.

Most diabetes patients we see in Patong fall into two groups: long-term expats whose home-country prescriptions have run out, and travellers diagnosed years ago who want a quarterly HbA1c without flying home. We also pick up new Type 2 diabetes during routine annual checks, often in people who simply felt thirsty and tired in the heat. Walk in, message us on WhatsApp, or ask reception at your hotel to call us.
How we diagnose diabetes and pre-diabetes
Diabetes is a chronic condition where blood glucose stays too high, either because the pancreas does not make enough insulin or because the body has become resistant to the insulin it produces. We confirm the diagnosis with any one of four criteria, repeated on a second occasion unless symptoms are unmistakable: HbA1c 6.5 percent or higher (48 mmol/mol), fasting plasma glucose 7.0 mmol/L or higher (126 mg/dL), random glucose 11.1 mmol/L or higher (200 mg/dL) with classic symptoms of thirst, frequent urination, and weight loss, or a two-hour oral glucose tolerance test result of 11.1 mmol/L or higher. Pre-diabetes is HbA1c 5.7 to 6.4 percent or fasting glucose 5.6 to 6.9 mmol/L, a high-risk state where structured lifestyle change cuts progression to diabetes by roughly 58 percent.
About nine in ten of our patients have Type 2 diabetes, driven by insulin resistance and a relative insulin deficiency. Type 1 diabetes, an autoimmune destruction of pancreatic beta cells that needs lifelong insulin, accounts for most of the rest. We also screen pregnant patients for gestational diabetes at 24 to 28 weeks, and consider monogenic diabetes (MODY) where a young, non-obese patient has a strong family history. Steroid-induced and other drug-induced hyperglycaemia is checked for in anyone on long courses of prednisolone.
Treatment ladder for Type 2 diabetes
Treatment is layered. Lifestyle is the foundation at every step: 5 to 10 percent weight loss, 150 minutes a week of moderate aerobic activity plus two resistance sessions, a Mediterranean or DASH eating pattern, smoking cessation, and alcohol moderation. Metformin remains first-line drug therapy, started at 500 mg twice daily and titrated to 1000 mg twice daily over four weeks, unless the kidneys are too impaired (eGFR below 30) or there is severe heart failure. From there, the second agent depends on what matters most for you: weight, cardiovascular history, kidney function, cost, and whether you can manage an injection.
Choosing your second-line agent
| Class / example | Weight | Cardio-renal benefit | Route, cost |
|---|---|---|---|
| Lifestyle | Loss | High, across all outcomes | Free, always step 1 |
| Metformin | Neutral or small loss | Modest, baseline therapy | Oral, very low cost |
| GLP-1 RA (semaglutide / Ozempic, tirzepatide / Mounjaro) | Strong loss (5 to 20 percent) | Strong, atherosclerotic disease | Weekly injection, high cost |
| SGLT2 inhibitor (empagliflozin / Jardiance, dapagliflozin / Forxiga) | Modest loss | Strong, heart failure and kidney | Oral daily, mid cost |
| DPP-4 inhibitor (sitagliptin / Januvia) | Neutral | Neutral | Oral daily, mid cost |
| Sulfonylurea (gliclazide) | Gain, hypoglycaemia risk | Neutral | Oral, very low cost |
| Insulin (basal glargine or premix) | Gain | Effective glucose lowering at any HbA1c | Injection, low to mid cost |
GLP-1 receptor agonists are our preferred add-on where weight loss and cardiovascular protection are the priorities. We start semaglutide or tirzepatide at the lowest dose and titrate slowly to limit nausea. SGLT2 inhibitors are preferred when heart failure, established atherosclerotic disease, or chronic kidney disease drives the decision; we counsel about genital thrush, dehydration in the Phuket heat, and the rare risk of euglycaemic ketoacidosis. Insulin is started when HbA1c stays above target on oral and injectable combinations, or earlier in symptomatic hyperglycaemia, usually as a single bedtime basal dose alongside existing therapy.
Annual screening we do not skip
Glucose numbers are only half the picture. Every diabetic patient at our clinic gets HbA1c every three months (or twice yearly if very stable), a fasting lipid panel and renal function yearly, urine albumin-to-creatinine ratio yearly for early kidney disease, blood pressure at every visit with a target below 130/80 mmHg, and a statin in almost all patients aged 40 to 75 to bring LDL cholesterol below 2.6 mmol/L (or below 1.8 mmol/L if there is established cardiovascular disease). We perform an annual foot examination with monofilament testing and pulse check, and we refer you for a dilated retinal photograph each year to a Phuket ophthalmology partner. Dental review once a year is part of the plan, because gum disease and diabetes worsen each other.
Acute and chronic complications
Acute decompensation is rare but dangerous. Diabetic ketoacidosis (DKA), seen mainly in Type 1, presents with thirst, frequent urination, nausea, abdominal pain, deep rapid breathing, and a sweet ketotic breath, and is a same-day emergency department visit. Hyperosmolar hyperglycaemic state (HHS) affects older Type 2 patients with very high glucose and severe dehydration, also an emergency. Hypoglycaemia is glucose below 3.9 mmol/L with sweating, tremor, hunger, or confusion, and is treated immediately with 15 grams of fast-acting carbohydrate (a small juice, three glucose tablets) and repeated after 15 minutes if not improved. Chronic complications, the reason all the screening above matters, include heart attack, stroke, peripheral arterial disease, diabetic retinopathy, kidney disease, and nerve damage in the feet.
Red flags, go to a hospital emergency department now: vomiting with abdominal pain and deep rapid breathing (possible DKA), drowsiness or confusion with very high glucose readings (possible HHS), severe hypoglycaemia not responding to oral sugar, a hot swollen red diabetic foot or a foot ulcer with fever (possible osteomyelitis), sudden loss of vision or new floaters (possible retinal bleed or detachment), and any chest pain or one-sided weakness.
See a doctor if you are thirsty and urinating frequently for more than a week, have lost weight without trying, have a family history of diabetes and have never been screened, are over 45 and have not had an HbA1c in three years, are pregnant and have not yet had your 24 to 28 week glucose test, or have run out of diabetes medication while travelling.
Prevention and self-care
For pre-diabetes and high-risk patients, the evidence is unambiguous: structured lifestyle change works better than any single tablet at preventing progression. We help you set realistic targets for weight, activity, and diet, and we keep the screening regular so any drift back is caught early. For established diabetics, the highest-impact prevention is the annual screening package, daily foot self-examination, never missing eye review, and matching travel insurance to your condition before you fly.
Prevention checklist: HbA1c every 3 months on treatment, annual lipid, renal, and urine albumin, annual dilated eye exam, annual foot exam plus daily self-check, blood pressure below 130/80, statin if aged 40 to 75, influenza vaccine yearly, pneumococcal vaccine once, and a medical ID bracelet if you use insulin.
Summary
Good diabetes care in Patong is not just about glucose: it is HbA1c every three months, the right second-line drug for your profile, blood pressure and lipids on target, and the eye, foot, and kidney screens that prevent the complications you cannot feel coming. We can start that plan in a single visit and keep it running for as long as you are in Phuket.
“A patient told us once that their old clinic only ever checked their sugar. We told them sugar is the headline, not the story. The story is your eyes, your kidneys, your feet, and your heart, and we want all five to outlive your diabetes.” Doctor Patong Takecare Clinic medical team
Frequently asked questions
How do I know if I am diabetic?
Classic symptoms are excessive thirst, frequent urination, unexplained weight loss, blurred vision, and persistent fatigue, although many people have no symptoms at all. We confirm with HbA1c 6.5 percent or higher, fasting glucose 7.0 mmol/L or higher, or random glucose 11.1 mmol/L or higher with symptoms. A single test can be done same day and we discuss results with you the same visit.
Can you prescribe Ozempic or Mounjaro for weight loss?
We prescribe GLP-1 receptor agonists such as semaglutide (Ozempic) and tirzepatide (Mounjaro) for Type 2 diabetes and, where medically appropriate, for obesity in patients with elevated cardiometabolic risk. We assess your medical history, run baseline blood tests, counsel you on nausea, dose titration, and rare side effects such as pancreatitis, and we review you regularly while on therapy.
Will travel or expat health insurance cover a diabetes consultation?
Most international insurers cover outpatient diabetes review, lab tests, and basic medications, although newer agents such as GLP-1s often need pre-authorisation. We issue itemised English-language receipts and a clinical summary that almost every insurer accepts for reimbursement, and we can liaise with your insurer for direct billing where the policy allows.
I am an expat in Phuket, can you refill my long-term diabetes medication?
Yes. Bring your current prescription or the actual packaging, your most recent HbA1c and kidney function results if you have them, and we will continue the regimen, repeat baseline labs, and provide a Thai prescription. If a medication is not available in Thailand, we will switch you to the closest licensed equivalent and explain the difference.
Where can I get the annual eye exam for diabetes in Phuket?
We refer to an ophthalmology partner in Phuket for a dilated retinal photograph, which is the standard annual screen for diabetic retinopathy. Bangkok Hospital Phuket and several private eye clinics in town offer the test, and we send your latest HbA1c and a referral letter so the ophthalmologist has full context.
What HbA1c should I be aiming for?
Most adults aim for HbA1c below 7.0 percent (53 mmol/mol). Younger, motivated, recently diagnosed patients can target below 6.5 percent if it can be achieved without hypoglycaemia. Older or frail patients, or those with established cardiovascular disease and a history of hypoglycaemia, are usually safer at below 8.0 percent. We agree your personal target with you and revisit it at every quarterly review.
