Gastroscopy
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 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.
Colonoscopy
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. It is crucial for colorectal cancer screening and is recommended for individuals aged 45 and older, or earlier if there is a family history of colorectal cancer.
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.
