Internal medicine clinic in Seoul, for everyday and long-term care

What our internal medicine clinic in Seoul covers

Internal medicine is the specialty that diagnoses and treats illness in adults without surgery. At our internal medicine clinic in Seoul, that means two kinds of care under one roof: short-term problems you want sorted out quickly, and long-term conditions that need a steady hand over months or years.

All care is led by Dr. HyunSung Park, board-certified in internal medicine in Korea, a gastroenterology subspecialist, ECFMG certified and a former clinical professor at Dongguk University Ilsan Hospital. He has treated patients in Korea since 2010 and consults one to one in English.

The pages in this section go into each area in more depth. This overview explains how the pieces fit together and how a visit works.

The main areas of care

• Digestive health: abdominal pain, reflux and GERD, indigestion, bloating, IBS-type symptoms, food poisoning, traveler's diarrhea, constipation and abnormal liver tests
• Metabolic health: high blood pressure, high cholesterol, prediabetes, type 2 diabetes and fatty liver evaluation
• Thyroid and blood: overactive or underactive thyroid, thyroid nodules seen on ultrasound, anemia, iron, vitamin D and B12 deficiency
• Everyday illness: colds, flu, sore throat, cough, urinary infections, rashes, hives and mild allergic reactions
• Headache and fatigue: a careful look for treatable causes before reaching for long-term medicines
• Ultrasound: abdominal and thyroid ultrasound performed in the clinic when the findings would change your plan

How the doctor decides what suits you

Every visit starts with a conversation. Dr. Park asks what is bothering you, how long it has been going on, what you take and what runs in your family. He examines you and then decides whether tests are needed at all.

Testing is targeted rather than packaged. A new cough may need nothing more than an examination, while recurring upper-abdominal pain may call for blood tests, an H. pylori test and an abdominal ultrasound. For long-term conditions, he agrees on clear targets with you and schedules rechecks only as often as they are useful.

When medicine is needed, he explains why, what side effects to watch for and how long you are likely to need it. He is just as willing to suggest stopping a medicine when it is no longer helping.

Who this clinic suits, and what we refer out

Our internal medicine clinic suits adults living in or visiting Seoul who want a specialist doctor, an explanation in English and a practical plan. Expats, students, business travelers and long-term residents use it both for one-off problems and as their regular doctor.

Some care is outside what a clinic like ours provides. Endoscopy, colonoscopy, surgery, emergency care, dentistry and plastic surgery are not offered here; we can refer you to a hospital and explain what to expect. Children and pregnancy care are usually better handled by a pediatrician or obstetrician.

Preparing for an internal medicine visit

A little preparation makes the visit faster and the advice more precise. If cholesterol or blood sugar tests are likely, fast for about 8 to 12 hours beforehand, drinking water only, and take your usual prescription medicines unless you have been told otherwise.

If you take high-dose biotin, mention it, because it can distort some thyroid and other blood results. Keep notes on when your symptoms started and what makes them better or worse; for blood pressure, a week of home readings is very useful.

• Passport or ID
• A list of medicines and supplements with exact doses
• Previous test results, scans or discharge letters, in any language
• Your insurer's claim form if you plan to claim

Safety and red flags

An outpatient clinic is not an emergency room. Call 119 in Korea or go straight to a hospital emergency department for chest pain, severe shortness of breath, signs of stroke such as face drooping or slurred speech, fainting, black or bloody stools, vomiting blood, severe abdominal pain, or a rapidly worsening allergic reaction with lip or throat swelling.

For less urgent but persistent symptoms, such as unexplained weight loss, difficulty swallowing or ongoing changes in bowel habit, book a visit soon rather than waiting; these deserve a proper assessment.
