What Functional Medicine Means Here
A structured whole-person assessment—without abandoning standard medical care.
Some health problems involve several overlapping factors: sleep, metabolic disease, medicines, nutrition, stress, physical activity and an existing diagnosis may all influence how a person feels.
The consultation organises these factors into a clinical timeline. The doctor checks for established medical explanations first, reviews what has already been tested and decides which next step is likely to be useful.
Lifestyle and complementary options may be discussed, but they are not substitutes for emergency care, appropriate medication, cancer treatment, infection treatment or specialist management.
π
Detailed History
Symptoms are connected to timing, diagnoses, treatment, travel, work and daily habits.
π§ͺ
Targeted Investigation
Standard laboratory or imaging tests are selected when clinically relevant.
π₯
Lifestyle Medicine
Nutrition, movement, sleep and stress management are translated into realistic actions.
π
Medication & Supplement Safety
Prescription, OTC, herbal and nutritional products are reviewed together.
Problems Commonly Reviewed
Functional assessment may help organise persistent, overlapping or unexplained concerns.
Persistent Fatigue
Review sleep, anaemia risk, thyroid, glucose, medicines, mood, infection history and activity patterns.
Digestive Symptoms
Bloating, altered stool, reflux or food-related symptoms are assessed for established GI causes and alarm features.
Sleep & Recovery
Insomnia, snoring, sleep schedule, shift work and possible sleep apnoea are considered.
Weight & Metabolic Risk
Weight history, glucose, blood pressure, lipids, fatty liver and appetite patterns may be reviewed.
Concentration & Mood
New cognitive, anxiety or depression symptoms require appropriate medical and mental-health assessment.
Complex Treatment Plans
Multiple medicines and supplements may create side effects, duplication or interaction concerns.
Your First Consultation
The visit begins with a timeline—not a preselected test package.
π©Ί
“Root cause” should be a clinical question, not a marketing promise.
A symptom can have more than one contributor. The goal is to identify plausible, treatable factors while screening for conditions that need standard medical care or referral.
ποΈ
Symptom Timeline
Onset, pattern, severity, triggers and previous response are mapped carefully.
π
Records Review
Bring laboratory reports, imaging, prescriptions, hospital summaries and prior diagnoses.
π₯£
Nutrition & GI History
Food pattern, appetite, bowel symptoms, restrictive diets and weight change are discussed.
π
Sleep, Work & Stress
Sleep timing, workload, caregiving, travel and recovery may shape symptoms.
π
Medication Inventory
List prescriptions, injections, vitamins, herbal products and exact doses.
π―
Prioritised Goals
Choose outcomes that are meaningful and possible to measure.
Testing Strategy
Useful testing should be valid, interpretable and capable of changing care.
The doctor reviews existing results first. Testing may include conventional blood work, imaging, endoscopy or referral depending on the clinical question.
β A Useful Test Usually Has
β
A clearly defined symptom, risk or diagnosis to investigate.
β
Known limitations and an understandable reference range.
β
A result that could alter treatment, monitoring or referral.
β
Appropriate preparation and clinical interpretation.
β
A follow-up plan for normal, abnormal or uncertain findings.
β οΈ Testing Deserves Caution When
!
A broad panel is sold before the medical problem is defined.
!
The test labels many foods or chemicals as harmful without clear clinical validation.
!
The result automatically leads to expensive supplements or prolonged restrictive diets.
!
False positives or uncertain findings may trigger unnecessary worry or procedures.
!
Testing delays appropriate conventional diagnosis or treatment.
More data is not always better medical care
Laboratory findings need context. A test can be analytically measurable yet still have uncertain value for diagnosing the symptom or deciding treatment.
Possible Assessment Areas
Testing and referrals are selected according to your history.
π©Έ
Metabolic Markers
Glucose, HbA1c, lipids, liver, kidney and blood pressure may be relevant.
π¦
Thyroid & Hormonal Review
Symptoms and existing results guide whether additional endocrine assessment is needed.
π§¬
Blood Count & Nutrients
Anaemia or selected deficiencies are assessed when history suggests risk.
π¦
GI & Infection Evaluation
H. pylori, coeliac disease, stool testing or endoscopy may be considered for defined indications.
π
Sleep Assessment
Sleep diaries, apnoea risk or referral may be useful for fatigue and poor recovery.
π«
Cardiovascular Risk
Family history, smoking, blood pressure, diabetes and lipid risk are integrated.
π§
Mood & Cognitive Health
Appropriate screening or referral is considered when symptoms affect daily function.
π¨βοΈ
Specialist Referral
Gastroenterology, endocrinology, mental health or other referral may be the correct next step.
Personalised Care Plan
From symptom map to practical treatment.
1
Clarify Priorities
Identify the main symptoms, safety concerns and desired outcomes.
2
Review Existing Evidence
Examine previous diagnoses, tests, treatment and response.
3
Investigate Selectively
Use examination, testing or referral where it can answer a question.
4
Treat & Support
Combine appropriate medicine, nutrition, movement, sleep and specialist care.
5
Reassess Outcomes
Measure progress and revise what is ineffective or unnecessarily burdensome.
Treatment Options
The plan may combine medical treatment with realistic lifestyle changes.
Nutrition Strategy
Build an adequate, sustainable eating pattern while avoiding unnecessary restriction.
Movement & Conditioning
Activity is progressed according to symptoms, fitness, pain and medical safety.

Continue, adjust or simplify treatment according to diagnosis, response and side effects.
Supplement Review
Use supplements selectively for an appropriate indication, dose and duration.
Measured Follow-Up
Track symptoms and objective markers without repeatedly testing everything.
Supplement & Complementary-Care Safety

FAQ
Functional medicine questions, answered.
The consultation is individual. Tests, supplements and treatments are considered only after reviewing the clinical problem, evidence, safety and alternatives.
Functional medicine is a whole-person style of medical assessment that reviews symptoms, medical history, lifestyle, medicines and relevant tests together. At this clinic it is used alongside, not instead of, evidence-based conventional care.
Not necessarily. This page describes a physician-led approach that keeps standard diagnosis, safety guidance and proven treatment central. Complementary approaches are considered only when their evidence, risks and interactions are understood.
The doctor reviews your symptom timeline, previous diagnoses, medicines, supplements, sleep, nutrition, activity, stress, family history and available records before deciding whether examination or targeted testing is needed.
Not automatically. Testing should answer a defined clinical question and be likely to change management. Previous results are reviewed first to avoid unnecessary duplication.
The doctor can assess symptoms related to food, allergy, coeliac disease or gastrointestinal conditions. Broad commercial panels are not ordered automatically, and any test should have a clear clinical purpose and interpretable result.
The clinic does not present detox products or cleanses as cures. Liver, kidney, gastrointestinal or toxic-exposure concerns require appropriate medical assessment and evidence-based management.
Yes. Herbal and dietary supplements can interact with prescriptions, affect bleeding or surgery, and create side effects. Bring a complete list of products and doses to the visit.
Persistent fatigue can be reviewed through sleep, nutrition, anaemia, thyroid, glucose, medicines, mood and other possible causes. Treatment depends on the cause identified rather than one universal fatigue protocol.
Follow-up may track symptoms, function, sleep, activity, weight, blood pressure or selected laboratory markers. Measures are chosen according to the original problem and treatment goal.
Yes. Apgujeong Hana Clinic provides English consultation, test explanation and follow-up for international patients in Seoul.
