If you require a capsule endoscopy, you’ll be asked not to eat anything and to drink only clear liquids the day before. You will be instructed to stop any oral intake the morning of the procedure. This helps make sure your digestive system is clear.
During the procedure, your GI nurse places a belt with sensors in it around your waist area. The sensors send signals to a recorder worn at your waist area. The sensors send signals to a recorder worn at your waist. Thin wires connect the electrodes to the transmitter. You swallow a capsule about the size of a large vitamin, which is specially coated so it’s easier to swallow.
If you’re having capsule endoscopy to check your small intestine, you’ll swallow the capsule and go home, wearing the belt and recorder around your waist. Usually, you’ll return the next day to return the belt and recorder. Your doctor connects the recorder to a computer and looks at video images of your digestive system to check for problems.
