Where to find it



  • Once preparation has started, you cannot ingest solid foods or milk. You may drink liquids up to 4 hours before the test (minimum time required for you to be put to sleep).
  • The bowel needs to be clean (no residue or stool). You will be given a preparation to evacuate your bowels, and you should follow the instructions precisely.

If you are a diabetic patient, check with your doctor to find out about the medication guidelines you should follow.


If you take...

  • Sintrom®, Aspirina®, Tromalyt®, Ibuprofen, Adiro®, Pradaxa®, or any other medication that may alter blood clotting, you should check with your family doctor if it is advisable to replace or suspend medication before the test
  • Iron supplements: stop taking 7 days before the test
  • You have to come accompanied, as you will be given a sedative before we do the test. You will not be able to drive any type of vehicle when leaving the Hospital


The day of the test 

  • You must shower and not wear any lipstick, nail varnish, false nails or jewellery
  • If you are a diabetic, notify the receptionist when you arrive
  • When you are called, the nurse will take you to the examination room where you will have to lie down on a stretcher
  • It is important you tell the nurse, before the examination, if you are allergic to any medication or food, if you have any heart or lung problems, if you wear a pacemaker and/or ICD (internal defibrillator), a valvular or vascular prosthesis or if you have any chronic infectious disease.
  • If you wear dentures, piercings and/or glasses, remove them before starting the test and leave them with your companion


How does it work?

  • This is done by means of a flexible endoscope, which is a rubber tube with a lens at its end that is connected to an optical video system.
  • This is inserted into the anus and CO2 gas is blown in during the test to see the walls of the gut properly, which can cause some discomfort due to abdominal distension, but this disappears shortly after
  • In some cases, biopsies can be taken and polyps removed, or other therapeutic techniques performed, where necessary. In case the patient needs a colon polypectomy, you should bring your last test results with the coagulation tests.


Test duration

The duration of this test is usually no longer than 30 minutes, as long as no therapeutic treatments are performed.


What should be done after the exploration?

  • You may notice some discomfort. Go to the bathroom as if you were trying to defecate, this will expel the air inside along with any leftover faeces
  • Do not eat or drink for an hour. After an hour you can start drinking liquids, followed with a light meal, and from then after you can continue with your usual diet
  • You can take your usual medication again unless you have been told otherwise


Go to A&E if you experience...

  • A lot of blood in your stools after a second visit to the toilet
  • Intense pain or repeated vomiting
  • Fever higher than 38.5ºC
  • Sweating, dizziness
