Capsule endoscopy (pillcam) at Spire London East Hospital

Swallow a pill-sized camera to investigate your small bowel.

A capsule endoscopy is a non-invasive way to investigate gastrointestinal bleeding, unexplained abdominal pain and conditions such as Crohn's disease. The procedure involves swallowing a pill-sized camera inside a capsule (the PillCam), which takes pictures of the small bowel.


Endoscopies are carried out in our JAG-accredited endoscopy unit. Learn more about the accreditation.

Why you might need it

The small bowel is fairly difficult to investigate using traditional methods. You might need to have a capsule endoscopy if an endoscopic examination of your colon or stomach has failed to determine the cause of your symptoms, which may include obscure gastrointestinal bleeding and abdominal pain.

Pain, diarrhoea or constipation can be symptoms of underlying intestinal problems. Diseases such as Crohn’s disease and ulcerative colitis can cause inflammation, or even ulceration, in your bowel.

If you've been diagnosed with iron deficiency anaemia (low red blood cell count), you may have a capsule endoscopy to help identify the cause. One common cause of anaemia is bleeding within the gut, which may be from the stomach, large bowel or small bowel. The bleeding may not always be obvious or visible, so tests like a capsule endoscopy may be helpful.

A capsule endoscopy could help to diagnose these conditions and to rule out more serious diseases, especially if you have visible bleeding from your back passage, which should never be ignored. The Pillcam can also be used to examine possible abnormalities of the intestine that show up on abdominal scans. It is used to monitor patients with refractory coeliac disease and intestinal polyps.

Before your treatment




Preparing for your treatment




The procedure


During a capsule endoscopy, you will swallow a capsule that contains a disposable, electronic, pill-sized camera, which takes continual pictures - about 100,000 over the course of 8 hours - during its passage through your gastrointestinal tract. The camera is about the size of a large vitamin pill (11mm x 26mm).

The images are recorded and stored in a reader that is worn on a belt around your waist. The capsule has an eight-hour battery life and usually passes naturally through your body with no need for retrieval.

During your appointment, which will last approximately half an hour, you will be connected to the equipment and instructed to swallow the capsule with a glass of water. You will be discharged and encouraged to go about your daily routine. You can usually drink two hours after swallowing the capsule, and have a light snack after a gap of four hours.

You will be asked to return the belt and reader either that evening or the following morning. The images will be downloaded onto a computer and viewed as a video stream by your consultant gastroenterologist.


You will be able to leave hospital after the procedure. Typically, results should be available to your referring doctor within three working days.

The Pillcam is disposable and will pass out of your body with a normal motion. You shouldn't experience any pain.

Looking after you

Even after you’ve left hospital, we’re still looking after you every step of the way. After a capsule endoscopy we will provide you with all the advice on what to do and not to do.

On rare occasions, complications following a capsule endoscopy can occur. The main risk associated with the procedure is intestinal obstruction, where the capsule becomes lodged in a narrowed area of the small bowel, and so it is not recommended for people with known or suspected gastrointestinal obstruction.

Capsule endoscopy is not recommended for pregnant women, and special precautions need to be taken if you have a cardiac pacemaker.
