Upper Digestive Endoscopy
A close examination of the upper digestive tract, without surgery.
Upper gastrointestinal endoscopy—also called gastroscopy or EGD—uses a thin, flexible camera to examine the lining of the esophagus, stomach and duodenum.
It can help investigate persistent digestive symptoms, identify inflammation or ulcers, evaluate bleeding and obtain tissue samples when visual findings require closer assessment.
At Apgujeong Hana Clinic, consultation and procedural care are coordinated under one roof. Dr. Yang Jae-hoon evaluates the reason for the examination, performs the gastroscopy and explains the initial findings directly.
Specialist Consultation First
Symptoms, medicines, previous test results and the reason for endoscopy are reviewed before the procedure.
High-Definition Examination
The lining of the upper digestive tract is inspected carefully for inflammation, ulcers, bleeding and abnormal tissue.
Biopsy When Appropriate
Small tissue samples may be collected for microscopic examination or selected infection testing.
Results Explained In English
Initial visual findings and the next steps are discussed after recovery, with written English documentation available.
Why Gastroscopy May Be Recommended
Endoscopy can investigate persistent symptoms and important warning signs.
The decision to perform gastroscopy depends on symptoms, age, medical history, medicines, previous treatment and examination findings.
๐ฅ
Persistent Heartburn
Long-lasting reflux, chest burning or symptoms that do not improve with appropriate treatment may require evaluation.
๐ฅฃ
Upper Abdominal Pain
Ongoing discomfort, burning, indigestion or unexplained pain may come from several upper digestive conditions.
๐ซ
Difficulty Swallowing
Food sticking, painful swallowing or progressively worsening swallowing difficulty requires medical assessment.
๐คฎ
Persistent Nausea or Vomiting
Recurrent symptoms may require examination for inflammation, ulcer disease, narrowing or another cause.
๐ฉธ
Possible Upper GI Bleeding
Vomiting blood, black stool or unexplained anaemia may indicate bleeding in the upper digestive tract.
๐
Unexplained Weight Loss
Unintentional loss of weight combined with digestive symptoms may justify prompt investigation.
๐ฆ
Gastritis or H. pylori
Endoscopy and biopsy may be used in selected patients when stomach inflammation or infection requires assessment.
๐ก๏ธ
Screening or Follow-Up
Individual risk factors, prior ulcers, previous abnormal findings or cancer-screening needs may influence timing.
Emergency symptoms should not wait for a routine clinic appointment
Vomiting a large amount of blood, black stool with faintness, severe chest or abdominal pain, breathing difficulty or loss of consciousness requires urgent emergency assessment.

Your Endoscopy Journey
From English booking to recovery and results.
01
๐ฌ
Contact The Clinic
Describe your symptoms, preferred date, medical conditions and whether you want to discuss sedation.
02
๐ซ
Follow Fasting Instructions
The clinic provides procedure-specific instructions about food, water and medicines.
03
๐ฉบ
Pre-Procedure Review
The doctor reviews symptoms, allergies, medicines, previous procedures and relevant health risks.
04
๐
Gastroscopy
The upper digestive tract is examined, with biopsy or another simple intervention when appropriate.
05
๐
Recovery & Results
Initial findings are explained after recovery. Pathology results require additional processing time.
Sedation & Comfort
Sedation is available, but the safest plan is individual.
๐
Comfort-focused gastroscopy in a monitored clinical setting.
Sedation may reduce awareness and anxiety during the procedure. Suitability depends on medical history, medicines, previous sedation experience and individual risk.
Pre-Sedation Review
Heart, lung, sleep-apnoea, allergy and previous anaesthesia or sedation history may affect the plan.
Medication Review
Tell the clinic about blood thinners, diabetes medicines, GLP-1 injections, insulin and all other prescriptions.
Procedure Monitoring
Breathing, oxygen level, pulse and blood pressure are monitored according to the sedation plan.
Post-Sedation Transport
Do not drive after sedation. Follow the clinic’s instructions about a companion, taxi and supervision.
Recovery Time
Patients remain in the recovery area until they meet the clinic’s discharge criteria.
No Guaranteed “Painless” Result
Comfort varies, and sedation reduces awareness rather than removing every possible sensation or risk.
Endoscopic Biopsy
Tissue samples can provide information that the camera alone cannot.
A biopsy involves passing a small instrument through the endoscope to collect tiny samples from selected areas of the lining.
๐ฌ
Microscopic Examination
A pathologist examines the tissue for inflammation, cellular changes and other abnormalities.
๐ฆ
H. pylori Assessment
Stomach tissue may help assess Helicobacter pylori in selected clinical situations.
๐งฉ
Targeted Sampling
Biopsy location and number depend on symptoms, appearance and the condition being investigated.
๐
Pathology Results
Laboratory analysis takes longer than the initial visual report and is explained when available.
Not every endoscopy requires a biopsy
The endoscopist collects tissue when it may improve diagnosis or management. Blood-thinning medicines and bleeding risk must be reviewed before the procedure.
Preparing For Gastroscopy
A clear stomach supports visibility and procedural safety.
The clinic sends fasting and medication instructions when your appointment is confirmed. Follow those instructions rather than using a generic schedule from another patient.
Food & Drink Fasting
Gastroscopy requires an empty stomach. The exact cut-off for food and clear liquids depends on the appointment and sedation plan.
Medication Instructions
Do not stop prescription medicine independently. Ask specifically about blood thinners, diabetes treatment and weight-loss injections.
Diabetes Planning
Fasting may require changes to insulin or other glucose-lowering medicine to reduce low- or high-glucose risk.
GLP-1 Medication Review
Tell the clinic if you use semaglutide, tirzepatide, liraglutide or another medicine that may affect stomach emptying.
Bring Relevant Records
Previous endoscopy reports, pathology results, medicine lists and recent medical information can improve planning.
Plan Your Return Home
Patients receiving sedation must not drive and should arrange transport according to clinic instructions.
After Gastroscopy
Most patients leave after a short monitored recovery period.
โ Common After-Procedure Experiences
โ
Temporary throat irritation or a mild scratchy sensation.
โ
Mild bloating or belching from air introduced during examination.
โ
Sleepiness, reduced concentration or slower reaction time after sedation.
โ
Waiting before eating or drinking until swallowing is considered safe.
โ
Initial findings explained before discharge when you are sufficiently alert.
โ ๏ธ Seek Prompt Medical Advice For
!
Severe or worsening chest, throat or abdominal pain.
!
Vomiting blood, black stool or significant ongoing bleeding.
!
Fever, breathing difficulty, fainting or marked weakness.
!
Persistent vomiting or inability to maintain fluids.
!
Any symptom identified as urgent in your discharge instructions.
Endoscopy Safety
Gastroscopy is generally well tolerated, but no procedure is risk-free.
๐ด
Sedation-Related Effects
Breathing, blood pressure, heart rhythm, nausea or medication reactions may require attention during or after sedation.
๐ฉธ
Bleeding
The risk is usually low but may increase after certain interventions or in patients using blood-thinning medicines.
๐งฑ
Perforation
A tear in the digestive tract is uncommon but is a serious complication requiring urgent treatment.
๐ซ
Aspiration
Stomach contents entering the airway is a reason fasting and medication instructions are important.
๐งช
Missed or Inconclusive Findings
No examination detects every condition, and repeat testing or another diagnostic method may sometimes be needed.
๐ฃ๏ธ
Individual Consent
The expected benefit, alternatives and relevant risks are reviewed according to your procedure and health history.
