What is Capsule Endoscopy?
Capsule endoscopy is a test doctors use to look inside your small intestine (part of your digestive system) using a tiny camera. But instead of using long tubes like in regular endoscopy, you just swallow a small capsule that contains a tiny camera inside it.
How Does It Work?
Once you swallow the capsule, it travels naturally through your digestive tract. As it moves, the camera inside takes thousands of pictures. These images are sent to a recording device that you wear on a belt. After 8–12 hours, the capsule usually comes out along with stools. You don’t need to retrieve it - you can flush it away.
Why is it Done?
Capsule endoscopy is often used to find out what’s causing:
- Unexplained bleeding from the intestine
- Ongoing stomach pain or diarrhea
- Conditions like Crohn’s disease or small intestine tumors
- Iron-deficiency anemia (low iron levels)
What Should You Do Before the Test?
A laxative is given to clean your bowel, so the camera gets clearer pictures. 4-6 hours fasting is required before the test.
Is it Safe?
Yes, for most people it’s very safe. But in rare cases, the capsule can get stuck, especially if there is a narrowing or blockage in your intestine. That’s why a CT scan is done prior to capsule endoscopy to check for any blockage in intestines.
Is it Painful?
No, there are no needles, no endoscopy required and no pain. Most people find it very easy and comfortable.
Summary
Capsule endoscopy is a modern, simple, and non-invasive way to look at your small intestine. It helps doctors diagnose problems that can’t be seen with regular scopes.
