Private gastroscopy services

A gastroscopy, also known as an upper endoscopy, is a procedure where a doctor uses a thin, flexible tube with a light and camera (endoscope) to look inside your esophagus, stomach, and the beginning of your small intestine. This imaging modality helps diagnose conditions such as ulcers, inflammation, tumors, and sources of bleeding. It is particularly useful for investigating symptoms like persistent heartburn, unexplained nausea and vomiting, stomach pain, difficulty swallowing, and gastrointestinal bleeding.

What to Expect

Preparation

You’ll need to fast (no food or drinks) for about 6-8 hours before the procedure to ensure a clear view of your upper digestive tract.

During the Procedure

You might receive a sedative to help you relax. The endoscope is gently passed through your mouth and into your stomach. The procedure usually takes about 15-30 minutes.

After the Procedure

You’ll rest until the sedative wears off, which usually takes about an hour. You may feel a bit bloated or have a sore throat, but these symptoms typically pass quickly.

Private colonoscopy services

A colonoscopy is a procedure where a doctor uses a similar tube to examine the inside of your colon and rectum. This helps detect polyps, tumors, inflammation, diverticulosis, and sources of bleeding. If you are between 50 and 74 years old, it is recommended that you undergo this screening test once every 2 years to screen for colorectal cancer (1). If you have a family history of colorectal cancer, your healthcare professional may suggest for you to start screening earlier.

What to Expect

Preparation

You’ll need to follow a special diet and take a bowel prep solution to clean out your colon. This ensures the doctor can see clearly.

During the Procedure

You’ll receive a sedative. The endoscope is inserted through the rectum to view the entire colon. The procedure usually takes about 30-60 minutes.

After the Procedure

You’ll need someone to drive you home. You might feel bloated or pass gas as the air introduced during the procedure moves out of your colon.

For many patients, these tests provide answers that explain years of ongoing discomfort or unexplained symptoms. Some conditions require additional investigation to confirm a diagnosis. For example, if your symptoms suggest food intolerances, we may recommend complementary testing, such as the lactose breath test, which can help diagnose lactose (dairy products) intolerance by measuring the hydrogen in your breath following the consumption of a lactose solution.
