Who Needs a Gastroscopy

A gastroscopy procedure is typically recommended by a gastro specialist in Singapore when patients experience symptoms such as:
Both Dr Koh and Dr Chan specialise in diagnosing and treating digestive health conditions. They may also recommend a gastroscopy procedure for monitoring existing conditions such as gastric ulcers, chronic gastritis or for more detailed investigations when initial tests raise concerns.

What Is a Gastroscopy

A gastroscopy procedure involves using a thin, flexible tube (endoscope) equipped with a camera to examine the oesophagus, stomach and duodenum. This procedure identifies conditions like:
  • Inflammation of the stomach lining
  • Stomach or duodenal ulcers
  • Polyps or tumours
  • Early signs of cancer
By providing a clear and detailed view of the upper gastrointestinal tract, a gastroscopy procedure enables early detection and intervention, which is critical for managing digestive health and improving long-term outcomes.

Why Proper Preparation Matters

Proper preparation is key to a successful gastroscopy in Singapore. When you follow the guidelines provided by our gastroenterologist, it helps:
  • Ensure the stomach is empty for clear and accurate results
  • Reduce the risk of complications during the procedure
  • Make the procedure quicker and more comfortable
  • Provide peace of mind during the diagnostic process
Dr Calvin Koh and Dr Webber Chan understand that undergoing a procedure like a gastroscopy can feel overwhelming. Their approach ensures you’re well-prepared, well-informed and well taken care of throughout your experience.

How to Prepare for Your Gastroscopy Procedure

To ensure your gastroscopy procedure goes smoothly, follow these practical steps as guided by our gastroenterologists:
  1. Follow the Fasting Guidelines
    You will need to fast for 6-8 hours before the procedure to ensure your stomach is empty. This means no food or drink, including water, during this time. Dr Koh or Dr Chan will provide specific instructions based on your procedure time.
  2. Review Medication Instructions
    Be sure to inform our gastroenterologists about any medications you take, especially blood thinners or diabetes medication. Depending on your case, our doctors may adjust or pause certain medications to prevent complications.
  3. Avoid Smoking or Alcohol
    Smoking and drinking alcohol can interfere with sedation and the results of the gastroscopy procedure. It’s advised to refrain from these at least 24 hours before your appointment.
  4. Dress Comfortably
    On the day of the procedure, wear loose, comfortable clothing and avoid jewellery or makeup. This will help you feel more relaxed during your visit.
  5. Arrange for a Companion
    Sedation is typically used during a gastroscopy procedure, so it’s important to arrange for someone to accompany you. They will help ensure you get home safely after the procedure.
  6. Communicate Any Health Concerns
    It’s important to inform your gastroenterologist of any health concerns you may have, such as allergies, heart conditions or respiratory issues. This will allow Dr Koh or Dr Chan to take appropriate precautions during the procedure.
  7. Plan for Aftercare
    After the procedure, you may experience mild bloating or discomfort in your throat. This is normal, but it’s important to follow the aftercare instructions provided by our gastroenterologists. If you have any concerns post-procedure, don’t hesitate to contact our clinic.
  8. Be Prepared for a Short Recovery Time
    Gastroscopy procedures are minimally invasive and typically require only a short recovery time. You may be observed for a brief period after the procedure to ensure you’re comfortable. Rest for the remainder of the day and refrain from any strenuous activities.

When to Contact Your Gastroenterologist

If you have any concerns or experience unusual symptoms, don’t hesitate to reach out to your gastro specialist in Singapore before your appointment. Contact Dr Koh or Dr Chan if:
  • You have a pre-existing medical condition, such as heart or lung disease
  • You develop a fever or any unusual symptoms leading up to your procedure
  • You’re unclear on medication or fasting instructions
