What Is Sedation Endoscopy?
Medication-supported comfort during gastroscopy or colonoscopy.
Sedation is a medication-induced reduction in awareness used to help suitable patients remain relaxed and comfortable during an endoscopic procedure.
It is different from simply receiving a throat spray, and it is not automatically the same as general anaesthesia. The depth of sedation can vary according to the procedure, patient response and clinical plan.
At Apgujeong Hana Clinic, sedation is available for both upper gastrointestinal endoscopy and colonoscopy after the doctor reviews your medical history, medicines, fasting status and individual risks.
Reduced Awareness
Sedation can reduce anxiety and awareness, although individual memory and experience may vary.
Improved Comfort
Medication may make it easier to tolerate the endoscope, positioning and procedural sensations.
Ongoing Observation
The clinical team monitors your response and adjusts care according to the intended sedation level.
Recovery Before Discharge
Sedative effects take time to wear off, so patients recover under supervision before leaving.
Understanding Sedation Depth
Sedation exists on a continuum rather than one fixed level.
The intended level is selected according to the procedure, your medical profile and the clinical team’s assessment. A patient’s response can change during a procedure.
01
Minimal Sedation
Relaxed but responsive
Anxiety may be reduced while the patient remains awake and able to respond normally to verbal communication.
02
Moderate Sedation
Sleepy with purposeful response
The patient may be drowsy and less aware but can generally respond purposefully to verbal or light physical stimulation.
03
Deeper Sedation
Greater reduction in awareness
Responsiveness and breathing support needs can differ. Deeper sedation requires an appropriate monitoring and rescue plan.
Sedation cannot guarantee complete unconsciousness or zero discomfort
Individual response varies. The goal is a safe, comfortable and technically successful procedure—not to promise that every patient will experience or remember exactly the same thing.
Who May Consider Sedation?
Sedation can be helpful for several procedural and personal reasons.
๐
Procedure Anxiety
Patients who feel highly anxious about gastroscopy or colonoscopy may find sedation helpful.
๐ฎ
Strong Gag Reflex
Sedation may improve tolerance of an upper endoscope in patients with a pronounced gag response.
๐
Previous Difficult Experience
A history of discomfort or incomplete examination can be discussed during planning.
โณ
Longer Procedure
Sedation may support comfort when biopsy, polyp removal or another intervention may extend the procedure.
2๏ธโฃ
Combined Procedures
Selected patients having gastroscopy and colonoscopy during one visit may discuss a coordinated sedation plan.
๐ง
Difficulty Remaining Still
Some physical, neurological or anxiety-related conditions can make positioning difficult.
๐ฌ
Possible Intervention
Biopsy or polyp removal may influence the expected procedure time and comfort strategy.
๐ฃ๏ธ
Personal Preference
Preferences are considered together with medical suitability, procedural need and available alternatives.
Pre-Sedation Assessment
Safe sedation begins before any medication is given.
๐ฉบ
Tell the clinic about every condition and medicine that could affect sedation.
The gastroenterologist and clinical team use this information to assess suitability, select a plan and determine whether additional precautions or hospital-based care may be more appropriate.
๐ซ
Heart & Blood Pressure
Heart disease, rhythm problems, chest symptoms and poorly controlled blood pressure require review.
๐ซ
Lung & Breathing History
Asthma, chronic lung disease, breathing difficulty and recent respiratory illness may affect planning.
๐ด
Sleep Apnoea
Loud snoring, witnessed breathing pauses, CPAP use and diagnosed sleep apnoea should be reported.
๐
Medicines & Allergies
Bring a complete list of prescriptions, injections, supplements and previous medication reactions.
๐งช
Previous Sedation
Tell the team about difficult sedation, severe nausea, prolonged recovery or anaesthesia complications.
๐คฐ
Pregnancy Possibility
Pregnancy, breastfeeding and fertility treatment should be discussed before medication is administered.
Fasting & Medication Instructions
An empty stomach reduces aspiration risk and supports safe examination.
Follow the instructions sent by Apgujeong Hana Clinic. Gastroscopy and colonoscopy have different preparation requirements, and your medicines may change the plan.
Stop Solid Food As Directed
The clinic commonly provides a food-fasting period before upper endoscopy. Colonoscopy also requires a separate bowel-preparation schedule.
Follow Clear-Liquid Timing
Clear liquids must also stop before sedation. Use the exact time provided for your appointment rather than a generic online schedule.
Diabetes Medicine Review
Fasting may require changes to insulin or glucose-lowering medicines. Do not adjust them without instructions.
GLP-1 Medicine Review
Report semaglutide, tirzepatide, liraglutide or other medicines that may affect stomach emptying.
Blood-Thinner Review
Aspirin, anticoagulants and antiplatelet medicines may affect biopsy or polyp-removal planning.
Arrange Transport Home
Do not drive after sedation. Follow the clinic’s instructions about a companion, taxi and supervision.
Do not stop an essential prescription independently
Contact the clinic before changing diabetes medicine, blood thinners, seizure medicine, heart medicine or another important treatment.

Sedation By Procedure
Gastroscopy and colonoscopy involve different sensations and preparation.
๐
Sedation Gastroscopy
A flexible endoscope passes through the mouth to examine the esophagus, stomach and duodenum.
โ
Sedation may reduce anxiety and awareness of gagging or throat sensations.
โ
Throat spray may also be used according to the clinical plan.
โ
Biopsy can be performed when appropriate.
โ
Eating resumes according to swallowing and discharge instructions.
๐
Sedation Colonoscopy
A flexible endoscope examines the colon after completion of bowel preparation.
โ
Sedation may reduce awareness of pressure, cramping and repositioning.
โ
High-quality bowel preparation remains essential even when sedation is used.
โ
Suitable polyps may be removed during the same procedure when appropriate.
โ
Recovery instructions may change after biopsy or polyp removal.
Recovery After Sedation
Feeling awake does not mean every sedative effect has disappeared.
๐ฟ
Rest under supervision before leaving the clinic.
Recovery time varies according to the medicine, procedure, dose, age, health conditions and individual response.
Alertness Check
The team assesses wakefulness, communication and readiness to follow discharge instructions.
Breathing & Circulation
Oxygen status, breathing, pulse and blood pressure are reviewed as appropriate.
Nausea or Dizziness
Symptoms are assessed before standing, walking or leaving the recovery area.
Procedure Findings
Initial results are explained when you are sufficiently alert. Pathology results take longer.
Written Instructions
Follow the clinic’s guidance about food, medicines, activity and warning symptoms.
Safe Transport
Arrange a companion or taxi and avoid driving after sedation.
Possible Sedation Risks
Most patients recover without a serious problem, but sedation is not risk-free.
๐ซ
Slowed Breathing
Sedation can reduce breathing effort or oxygen level, especially with deeper medication effects.
๐
Blood Pressure Changes
Blood pressure may decrease or fluctuate in response to medication, fasting or an underlying condition.
๐ซ
Heart-Rhythm Changes
Pulse or rhythm changes can occur and may require observation or treatment.
๐คฎ
Nausea or Vomiting
Some patients experience nausea, vomiting or dizziness during recovery.
๐ซ
Aspiration
Stomach contents entering the airway is an important reason to follow fasting instructions.
๐จ
Medication Reaction
Allergic or unexpected medication reactions are uncommon but can require urgent treatment.
Some patients may need a different setting or sedation strategy
Significant heart or lung disease, severe sleep apnoea, difficult airway history, unstable illness or another major risk may change whether office-based sedation is appropriate.

FAQ
Sedation endoscopy questions, answered.
Sedation suitability and preparation are individual. Contact the clinic before fasting or changing any prescription medicine.
Not necessarily. Sedation exists on a continuum. Some patients are very sleepy and remember little, while others retain partial awareness. The intended level is selected according to the procedure and medical assessment.
Yes. Apgujeong Hana Clinic offers sedation for both gastroscopy and colonoscopy after reviewing medical suitability, fasting status and procedural requirements.
Sedation commonly improves comfort and reduces awareness, but no clinic can guarantee that every patient will experience zero sensation or have no memory of the procedure.
The clinic sends procedure-specific fasting instructions. Gastroscopy and colonoscopy preparation differ, and medicines such as insulin or GLP-1 injections may require additional planning.
Sleep apnoea does not automatically prevent sedation, but it can increase breathing risk. Tell the clinic about snoring, CPAP use, previous sleep studies and any breathing problems.
Do not stop these medicines independently. Tell the clinic which product you use, your dose, your last injection and whether you have nausea, vomiting or prolonged fullness so individual instructions can be provided.
No. Do not drive after sedation. Arrange a companion, taxi or other transport according to the clinic’s discharge instructions.
Recovery time varies with the medicine, dose, procedure and patient. You remain under observation until the clinical team considers discharge appropriate.
Initial visual findings are generally explained after you recover sufficiently. Biopsy and pathology results require additional processing and are reviewed later.
