Gastroscopy and Colonoscopy: What is the Difference?
When it comes to diagnosing digestive health issues, two of the most effective tools used by specialists are gastroscopy and colonoscopy. While both fall under the category of endoscopy (meaning looking inside the body with a camera), they serve very different purposes and examine different parts of the gastrointestinal tract. At LifeCare Hospitals, we utilize state-of-the-art endoscopic equipment to ensure precise diagnosis and comfortable care. (Read our guide on Stomach Ulcers).
What is a Gastroscopy?
A gastroscopy, also known as an Upper GI Endoscopy, involves passing a thin, flexible tube (an endoscope) through the mouth and down into the stomach. This allows the gastroenterologist to examine the esophagus, the stomach, and the first part of the small intestine (the duodenum).
Why It's Performed:
- To investigate symptoms like persistent indigestion, heartburn, or abdominal pain.
- To diagnose conditions such as Stomach Ulcers, GERD, or Celiac disease.
- To screen for stomach or esophageal cancer.
What is a Colonoscopy?
A colonoscopy is a procedure used to examine the entire large intestine (the colon) and the rectum. The endoscope is inserted through the rectum. This is the gold standard for detecting and preventing colorectal cancer.
Why It's Performed:
- To screen for colon cancer and remove polyps (small growths that could become cancerous).
- To investigate changes in bowel habits, rectal bleeding, or unexplained weight loss.
- To monitor inflammatory bowel diseases (IBD) like Crohn's disease or ulcerative colitis. (See our Digestive Health Tips).

Frequently Asked Questions (FAQs)
Are these procedures painful?
With the sedation we provide, most patients feel no pain and have little memory of the procedure itself. You may feel some mild bloating afterward, which passes quickly.
How long do the procedures take?
A gastroscopy usually takes 15-20 minutes, while a colonoscopy can take 30-45 minutes. You will then spend about an hour in the recovery room before being discharged.
