Capsule EndoscopyCapsule endoscopy is a technology that uses a swallowed video capsule to perform painless endoscopic imaging of the middle part of the gastrointestinal tract that helps evaluating intestine problems. Capsule endoscopy helps doctors to diagnose the causes for recurrent or persistent symptoms such as abdominal pain, diarrhea, bleeding or anemia.


Patient only needs to swallow a video capsule (11mm x 26mm). As the capsule travels through the esophagus, the camera encases will take photographs. The images are transmitted to a recording device worn on the abdomen of the patient during the entire procedure. This will not affect the normal activities of the patient.
Generally, the capsule will stay in the stomach for 2 hours and it takes about 3-4 hours to pass through the small intestine. It takes about 2 hours for doctor to review all the images.


  • Please maintain a clear fluid diet 1 day before the procedure. Patients may have porridges, sports drinks or filtered fruit juice. Do not drink milk or any milk products. Fast 8 hours before the capsule endoscopy.
  • The nurse will attach the receiving device to your abdomen which is connected with the data recorder, it will be wore on the waist.
  • Swallow the capsule with some water.
  • Please fast for 2 hours after swallowing the capsule, follow the instructions of the doctor and take some clear fluids.
  • The receiving device, data recorder and the waist belt will be removed after 8 hours.
  • Resume normal diet as your doctor advises
  • Patients should keep the record of time for having food and activities on the examination day.
  • After the procedure, the doctor will review the images received. Normally, the capsule will be discharged in 24 hours after the examination.
