Capsule Endoscopy – Non-Invasive Evaluation of the Small Intestine in South Delhi
Capsule Endoscopy is a non-invasive diagnostic procedure that allows doctors to examine the small intestine — a 20+ foot long section of the digestive tract that lies beyond the reach of standard upper endoscopy and colonoscopy. Instead of a traditional scope, the patient swallows a small capsule, about the size of a large vitamin pill, that contains a tiny camera, light source, and wireless transmitter.
As the capsule travels naturally through the esophagus, stomach, small intestine, and eventually the colon, it captures thousands of images and wirelessly transmits them to a small recorder worn on a belt around the patient's waist. This makes Capsule Endoscopy one of the least invasive ways to visualize the small bowel, requiring no sedation, no scope insertion, and no downtime.

Why Is Capsule Endoscopy Recommended?
Capsule Endoscopy is recommended when your doctor needs a detailed view of the small intestine, especially when other diagnostic tests have not identified the cause of your symptoms.
Unexplained GI Bleeding or Anemia
Identifies the source of obscure gastrointestinal bleeding or unexplained iron-deficiency anemia when upper endoscopy and colonoscopy are normal.
Suspected Crohn's Disease
Detects inflammation, ulcers, or narrowing in the small intestine that may indicate Crohn's disease.
Small Bowel Tumors or Polyps
Helps identify tumors, polyps, or abnormal growths in the small intestine, especially in high-risk patients.
Chronic Abdominal Pain or Diarrhea
Evaluates persistent digestive symptoms when routine blood tests and imaging have not found the cause.
Celiac Disease Evaluation
Assesses the extent of small bowel damage in patients with confirmed or suspected celiac disease.
Follow-up After Abnormal Imaging
Confirms and further evaluates abnormalities detected on CT scans, MRI, or other diagnostic investigations.

How Does the Capsule Endoscopy Procedure Work?
Preparation
You will typically be asked to fast for about 12 hours before the procedure, similar to preparing for a standard endoscopy, and may need clear liquids the evening before.
Swallowing the Capsule
At your appointment, you swallow the vitamin-pill-sized capsule with a glass of water — no sedation or anesthesia is required.
Wearing the Recorder
A small recording device is worn on a belt around your waist for 8 to 12 hours while the capsule travels through your digestive tract, wirelessly capturing images.
Going About Your Day
You can typically return to work and most normal activities during the recording period, though your doctor may advise avoiding strenuous exercise or MRI machines until the capsule has passed.
Capsule Passage
The capsule is disposable and passes naturally in a bowel movement within 24 to 48 hours — no retrieval is necessary.
Image Review
You return the recording device to the clinic, and your doctor reviews the thousands of captured images to identify any abnormalities.

Frequently Asked Questions
Find answers to common questions about Capsule Endoscopy, including why it's recommended, how it works, and what to expect afterward.
Capsule Endoscopy is a non-invasive procedure in which a patient swallows a small, pill-sized camera that travels naturally through the digestive tract, capturing thousands of images of the small intestine as it passes through—an area that is difficult to reach with traditional endoscopy or colonoscopy.
Capsule Endoscopy is commonly used to investigate unexplained gastrointestinal bleeding, unexplained anemia, suspected Crohn's disease, small bowel tumors or polyps, and chronic abdominal pain or diarrhea when other tests have not identified the cause.
No. Capsule Endoscopy is completely painless and does not require sedation. The capsule is swallowed like a large pill, and most patients feel nothing as it moves through the digestive tract.
The capsule typically takes 8 to 12 hours to pass through the digestive tract while continuously recording images, though you can go about most normal daily activities during this time. The initial appointment to swallow the capsule and attach the recording device takes about 30 minutes.
The capsule is disposable and passes naturally out of the body in a bowel movement within 24 to 48 hours, so no retrieval is needed. The recording device is returned to the clinic, and your doctor reviews the images to determine if any abnormalities were found.
