Capsule endoscopy preparation

Overview

Capsule endoscopy is a test that uses a tiny, pill-sized camera to take pictures of your digestive tract. You swallow the capsule, and it travels through your body, sending images to a recorder you wear on a belt. The preparation helps make sure the camera gets clear pictures.

doctors use capsule endoscopy fairly often when they need to see parts of the small bowel that are hard to reach with other scopes.

it is used for people who may have bleeding, inflammation, or growths in the small bowel. Your doctor will decide if you need it.

Symptoms

Causes

Main causes

• to find the source of bleeding or anaemia when other tests were normal
• to look for inflammation (like Crohn's disease)
• to check for polyps or tumours in the small bowel

Risk factors

• difficulty swallowing or a known narrowing (stricture) in the bowel
• pregnancy – tell your doctor if you might be pregnant
• if you have a pacemaker or other implanted medical device

When to see a doctor

See a doctor urgently if:

• if you have severe pain or bloating during the preparation or after swallowing the capsule

Book a routine appointment if:

• if you were given a bowel preparation and you cannot keep it down or it causes severe discomfort

Diagnosis

capsule endoscopy is a diagnostic test itself. The preparation is needed to get a clear view. Your doctor will review the images over the next day or two.

Tests that may be done

• swallowing the capsule and wearing a data recorder for about 8 hours
• a follow-up appointment to discuss results

What to expect at your appointment

you will usually need to follow a clear liquid diet for 24 hours before the test, and take laxatives to clean out your bowel. You will swallow the capsule with water. You can go about your normal day but avoid strenuous activity. You must not eat until your doctor says it is safe, usually after 4-8 hours. The capsule will pass naturally in your stool within a few days.

Treatment

capsule endoscopy does not treat a condition – it helps find the problem. After the test, your doctor will discuss what to do next based on the images. This may include further tests, medication, or lifestyle changes.

Self-care at home

• follow the exact diet and fasting instructions your doctor gives you
• drink only clear fluids (water, apple juice, black tea or coffee without milk) during the preparation
• avoid red or purple coloured drinks and foods
• take all laxatives exactly as prescribed

Medical treatments

if the capsule shows a problem, your doctor may recommend medicines to reduce inflammation, treat infection, or stop bleeding. They may also suggest another endoscopic procedure or surgery. No specific drug names or doses are given here – always follow your doctor’s advice.

When is surgery considered?

if the capsule finds a blockage, severe bleeding, or a growth, surgery may be needed to remove it. Your specialist will explain if this applies to you.

Living with this condition

capsule endoscopy is a one-time test. For most people, life returns to normal right after the capsule passes. There are no lasting effects.

Lifestyle tips

• resume your normal diet once the test is over – your doctor will tell you when
• drink plenty of fluids to help the capsule pass

Diet and exercise

you can eat and drink normally after the test. Light activity is fine. Avoid heavy exercise until the capsule has left your body (usually 1-3 days).

Mental health and emotional wellbeing

worry about test results is normal. Talk to your doctor about your concerns. Remember that finding the problem is the first step to feeling better.

Prevention

the test is used to find problems – it does not prevent them. Following your preparation instructions carefully helps make sure the test works well and may avoid a repeat.

Screening programmes

capsule endoscopy is not a routine screening test. It is used when symptoms suggest a problem in the small bowel.

Complications

If left untreated

• the capsule may get stuck if you have a narrowing in the bowel – this is rare, but your doctor will check for this beforehand
• if the bowel is not clean enough, the images may not be clear and you may need to repeat the test

Long-term outlook

capsule endoscopy is a safe, well-tolerated test. Most people find it easy to do. The results often give your doctor valuable information to guide your care and improve your health.
