A telescopic examination of the oesophagus, stomach and duodenum can show changes in the mucous membrane such as infection or wounds.

The examination is conducted with a flexible telescope that is lead in through the mouth down the oesophagus to the stomach and duodenum. It is necessary to inflate the stomach with air, which may cause discomfort and pressure in the stomach. It is completely harmless. Tests can be taken from the mucous membrane, which is painless.

The examination will last approximately 5-10 minutes, though you must expect to spend time on preparation and information both before and after the examination.

Your stomach must be empty so the mucous membrane is visible.

If it is necessary during the examination to give medicine to help you relax or relive pain, you are not allowed to drive a car for 24 hours after the examination.

If you need local anaesthesia in your throat, you must not eat anything for 2 hours after your examination.

A coloscopy examination can show changes in the colon such as polyps, diverticulosis, tumours or inflammatory conditions. The examination is performed with a long flexible tube with a camera which is inserted through the rectum.

It is necessary to inflate the colon with air, which may cause the feeling of bloating and urge to have bowel movements. You may experience pain, but it is brief and caused by stretching of the colon.

If it is necessary during the examination to give medicine to help you relax or relive pain, you are not allowed to drive a car for 24 hours after the examination.

Biopsies can, if necessary, be taken from the mucous membrane, which is painless.

The examination lasts approximately 45 minutes. You must expect to spend time on preparation and maybe resting after the examination. This together with the examination will last two to three hours.

You may feel some discomfort in your throat but that will disappear after a day or two. Bloating of the stomach will disappear after a few hours.

You will receive the result of your examination before you leave the clinic. If biopsies are taken, the results will be ready in 8 weeks.

There is a very small risk of perforating the colon.

If you experience:

• severe abdominal pain
• bloody or black stools
• discomfort, nausea, or a tendency to sweat
• fever above 38 degrees Celsius
• shivers

you should contact the Emergency Medical Service in the first 24 hours after the examination.

After the first 24 hours you should contact your general practitioner.

I would like to cancel my appointment because my symptoms have disappeared. How can I do that?

• Send an e-mail with the reason why you want to cancel via the link in your admission letter or call us. We will let the referring doctor know that you have canceled your appointment.

Can I take my usual medications in the morning?

• Yes, but you may not take any diuretic tablets and tablets for diabetes.

I have eaten seeds in the days up to my appointment because I received my appointment with a very short notice. What then?

• We are aware of that you cannot always adhere to the rules when we call you in on a short notice. Refrain from seeds as long as you can.

Why can I not take iron tablets in the days before the colonoscopy?

• The iron will make it difficult to be sufficiently empty and it creates a green film on the mucous membrane. If you are called in on a short notice stop taking the iron tablets as quickly as possible.

Can I wear jewelry at the examination?

• We recommend that you do not wear jewelry at your examination since they are electrical conductors and can get stuck when you need to move around on the examination bed.

When does the purgative work?

• As described above it works after approximately 1 hour, and diarrhoea will be over approximately 1½-2 hours later. It is individual when the purgative works. If your faeces is watery then the purging is sufficient.

What happens if I take the purgative earlier than 8 pm and 5 hours before my appointment?

• It is important that you follow the instructions in our guide. Otherwise, the doctor or endoscopy nurse may not be able to see the mucous membrane, and in the worst-case scenario, you may need to repeat the purging process and reschedule your appointment.

Is it possible to conduct the colonoscopy while I have my period?

• Yes, the examination can still be conducted. You can bring extra sanitary pads/tampons into the examination room.

Why am I not allowed to drive a vehicle or a bicycle after the examination? And when am I allowed to again?

• If you get medicine to help you relax or relieve pain during your examination, your power of concentration and reaction are reduced considerably. It corresponds to consuming alcohol or drugs. Out of consideration for traffic and work safety you must not drive a vehicle, work equipment and bicycles for 24 hours after your examination.

Can I go to work right after the colonoscopy?

• We recommend that you take the rest of the day off, so you/your body can recover from fasting and purging.

Why did I get a message about taking a break from blood thinning medication, when you usually can continue taking it?

• Some types of blood thinning medications can affect the bloods ability to coagulate enough, that severe complications can occur if we are not aware that you are taking that type of medication. That is why we sometimes ask you to take a break from your blood thinning treatment and if necessary give you something else in stead.

When will my stomach return to normal again after the examination?

• Some patients experience having different faeces (consistency and frequency) for some time after the purging - it varies from a few days to 1-2 weeks.

Is there a risk of me having faeces in my pants on my way to my appointment?

• We have studied this and the risk is very small - it rarely happens.
