A Patient’s Story
When Michael was advised to undergo a gastroscopy to investigate ongoing indigestion, his first reaction was anxiety. He had concerns about gagging, sedation, and needing time away from work.
During his consultation at LSDC, he learned about transnasal gastroscopy, an option designed to improve comfort while maintaining diagnostic accuracy. Understanding how the procedure worked helped him feel reassured and in control before the test.
What Is a Transnasal Gastroscopy?
A transnasal gastroscopy is a minimally invasive diagnostic procedure used to examine the upper gastrointestinal tract, including the oesophagus, stomach, and the duodenum.
Unlike conventional gastroscopy, this technique uses a thin, flexible camera that is passed gently through the nose rather than the mouth. This approach significantly reduces the gag reflex, making the procedure better tolerated for most patients.
Because of this improved tolerance, the examination is usually performed without sedation, allowing for a faster recovery and an immediate return to daily activities.
Why Might You Need a Transnasal Gastroscopy?
Your doctor may recommend this investigation if you are experiencing:- Persistent heartburn or indigestion
- Upper abdominal pain
- Nausea or vomiting
- Difficulty or pain when swallowing
- Unexplained weight loss or anaemia
This examination enables specialists at LSDC to diagnose conditions such as gastritis, peptic ulcers, infections, and coeliac disease. If necessary, a biopsy may be taken. This involves removing a very small tissue sample, is painless, and allows for accurate laboratory analysis.

Choosing a transnasal approach often means a more comfortable, safe, and convenient experience. At LSDC, patient wellbeing and clinical excellence remain the priority.1. No Sedation Required
Most patients remain fully awake, reducing medical risk and eliminating recovery delays.
2. Greater Comfort and Control

3. Rapid Recovery
There is no post-procedure grogginess, and most patients feel well immediately.
4. Return to Daily Activities
You can usually eat, drink, and drive within a short time after the procedure.
How Does It Compare With Conventional Gastroscopy?
| Feature | Transnasal Gastroscopy | Conventional Gastroscopy |
|---|---|---|
| Entry route | Through the nose | Through the mouth |
| Gag reflex | Rarely triggered | Common |
| Sedation | Usually not required | Often required |
| Recovery | Almost immediate | Several hours |
| Driving | Permitted immediately | Not permitted for 24 hours |
What to Expect During Your Visit to LSDC
Before the Procedure
An empty stomach is essential for a safe and accurate examination. You should not eat or drink for six hours beforehand.Essential medications may be taken with a small sip of water.
On arrival, the LSDC clinical team will confirm your details and answer any remaining questions. Shortly before the test, a local anaesthetic and decongestant spray are applied to the nose to enhance comfort.
During the Procedure
You will be comfortably seated. The specialist gently guides the ultra-thin endoscope through one nostril. Your breathing is not affected. A small amount of air may be introduced to improve visibility, which can feel unusual but is not painful. The procedure typically lasts 5 to 10 minutes.
After the Procedure
You may rest briefly while the numbness wears off, usually within 30 to 60 minutes. The specialist will explain the initial findings immediately and provide a written report. If biopsies were taken, results are usually available within one week. You can then continue with your day as normal.
Risks and Safety
A transnasal gastroscopy is considered a very safe and low-risk investigation.
- Mild nasal congestion or sore throat
- A minor nosebleed
- Short-lived bloating
Serious complications such as bleeding or perforation are extremely rare. At LSDC, all procedures are performed by experienced specialists following strict safety protocols.
