Ozempic in Seoul, prescribed for the right reason

How Ozempic care works at our Seoul clinic

Ozempic is a once-weekly injection of semaglutide, a GLP-1 receptor agonist, licensed to improve blood sugar control in adults with type 2 diabetes alongside diet and exercise. It also lowers appetite and slows stomach emptying, so many people lose weight. Large studies have shown cardiovascular benefits in people with type 2 diabetes and established heart disease.

When you ask about Ozempic in Seoul at VEI Clinic, Dr. HyunSung Park, a board-certified internal medicine specialist with an ECFMG certificate and training from the State University of New York, first looks at the whole picture: your blood sugar, kidneys, liver, heart risk, other medicines and goals. If you have type 2 diabetes, Ozempic may be a good fit. If your main goal is weight management without diabetes, Wegovy, which contains the same ingredient at a higher licensed dose, or another option is usually more appropriate. Using Ozempic for weight alone is off-label, so we only consider it after a careful discussion.

Who Ozempic suits, and who should avoid it

Ozempic suits adults with type 2 diabetes whose blood sugar needs better control, particularly those who are also overweight, have fatty liver or carry cardiovascular risk. It is not a replacement for insulin and is not used in type 1 diabetes or diabetic ketoacidosis.

It should be avoided, or used only with extra care, if you have:

• A personal or family history of medullary thyroid cancer, or MEN2
• Pregnancy, breastfeeding, or plans to become pregnant within about two months
• A history of pancreatitis or current gallbladder problems
• Diabetic retinopathy, which needs an eye check before and during treatment
• Severe kidney disease or frequent dehydration
• Insulin or sulfonylurea use, where doses may need lowering to avoid hypoglycemia

Getting started: tests, dosing and self-injection

Baseline tests usually include HbA1c, fasting glucose, kidney and liver function, lipids and a urine albumin-to-creatinine ratio. If you already have results from another clinic, bring them, since they may avoid repeat testing. We also ask about your last eye examination.

Ozempic starts at 0.25 mg weekly for four weeks, a dose meant only to let your body adjust, then usually moves to 0.5 mg. If more blood sugar control is needed, it can be raised further after at least four weeks at each step. The first injection is taught in the clinic, and you then inject yourself at home on the same day each week, in the abdomen, thigh or upper arm. Your written plan explains storage, missed doses and what to do on days you are ill and cannot eat.

Medicine works better alongside steady habits. At each review Dr. Park looks at your meals, protein intake, activity, sleep and alcohol, and suggests one or two realistic changes rather than a rigid diet. Strength exercise twice a week helps protect muscle as weight falls, and regular home glucose checks show how food and dose changes affect you.

Side effects and practical tips

Nausea, vomiting, diarrhea, constipation, bloating and reduced appetite are the most common effects, mainly at the start and after dose increases. Eat smaller, slower meals, stop when you are comfortably full, choose lower-fat foods and drink water through the day. Most stomach effects ease over a few weeks; if not, the dose step can be delayed.

Serious risks are less common but important: pancreatitis, gallstones, kidney problems from dehydration, low blood sugar when combined with insulin or a sulfonylurea, and possible worsening of diabetic retinopathy when blood sugar falls quickly. Tell any doctor planning sedation, endoscopy or surgery that you use Ozempic, as it slows stomach emptying.

Red flags: when to call 119

Call 119 or go to an emergency department for severe, constant upper abdominal pain that may spread to the back, persistent vomiting, signs of dehydration such as fainting or very little urine, pain under the right ribs with fever or yellowing of the skin, black or bloody stools, or swelling of the face and throat with trouble breathing. Contact us promptly for blurred vision, a lump in the neck, difficulty swallowing, or repeated low blood sugar readings.
