A colonoscopy (koh-luh-NAH-skuh-pee) allows a doctor to look inside the entire large intestine. The procedure enables the physician to see things such as inflamed tissue, abnormal growths, and ulcers. It is most often used to look for early signs of cancer in the colon and rectum. It is also used to look for causes of unexplained changes in bowel habits and to evaluate symptoms like abdominal pain, rectal bleeding, and weight loss.
The colon, or large bowel, is the last portion of your digestive tract, or gastrointestinal tract. The colon is a hollow tube that starts at the end of the small intestine and ends at the rectum and anus. The colon is about 5 feet long, and its main function is to store unabsorbed food waste and absorb water and other body fluids before the waste is eliminated as stool.
Preparation
You will be given instructions in advance that will explain what you need to do to prepare for your colonoscopy. Your colon must be completely empty for the colonoscopy to be thorough and safe. To prepare for the procedure you will have to follow a liquid diet for 1 to 3 days beforehand. The liquid diet should be clear and not contain food colorings, and may include
fat-free bouillon or broth
strained fruit juice
water
plain coffee
plain tea
diet soda
gelatin
Thorough cleansing of the bowel is necessary before a colonoscopy. You will likely be asked to take a laxative the night before the procedure. In some cases you may be asked to give yourself an enema. An enema is performed by inserting a bottle with water and sometimes a mild soap in your anus to clean out the bowels. Be sure to inform your doctor of any medical conditions you have or medications you take on a regular basis such as
aspirin
arthritis medications
blood thinners
diabetes medication
vitamins that contain iron
The medical staff will also want to know if you have heart disease, lung disease, or any medical condition that may need special attention. You must also arrange for someone to take you home afterward, because you will not be allowed to drive after being sedated.
Procedure
For the colonoscopy, you will lie on your left side on the examining table. You will be given pain medication and a moderate sedative to keep you comfortable and help you relax during the exam. The doctor and a nurse will monitor your vital signs, look for any signs of discomfort, and make adjustments as needed.
The doctor will then insert a long, flexible, lighted tube into your rectum and slowly guide it into your colon. The tube is called a colonoscope (koh-LON-oh-skope). The scope transmits an image of the inside of the colon onto a video screen so the doctor can carefully examine the lining of the colon. The scope bends so the doctor can move it around the curves of your colon.
You may be asked to change positions at times so the doctor can more easily move the scope to better see the different parts of your colon. The scope blows air into your colon and inflates it, which helps give the doctor a better view. Most patients do not remember the procedure afterwards.
The doctor can remove most abnormal growths in your colon, like a polyp, which is a growth in the lining of the bowel. Polyps are removed using tiny tools passed through the scope. Most polyps are not cancerous, but they could turn into cancer. Just looking at a polyp is not enough to tell if it is cancerous. The polyps are sent to a lab for testing. By identifying and removing polyps, a colonoscopy likely prevents most cancers from forming.
The doctor can also remove tissue samples to test in the lab for diseases of the colon (biopsy). In addition, if any bleeding occurs in the colon, the doctor can pass a laser, heater probe, electrical probe, or special medicines through the scope to stop the bleeding. The tissue removal and treatments to stop bleeding usually do not cause pain. In many cases, a colonoscopy allows for accurate diagnosis and treatment of colon abnormalities without the need for a major operation.
During the procedure you may feel mild cramping. You can reduce the cramping by taking several slow, deep breaths. When the doctor has finished, the colonoscope is slowly withdrawn while the lining of your bowel is carefully examined. Bleeding and puncture of the colon are possible but uncommon complications of a colonoscopy.
A colonoscopy usually takes 30 to 60 minutes. The sedative and pain medicine should keep you from feeling much discomfort during the exam. You may feel some cramping or the sensation of having gas after the procedure is completed, but it usually stops within an hour. You will need to remain at the colonoscopy facility for 1 to 2 hours so the sedative can wear off.
Rarely, some people experience severe abdominal pain, fever, bloody bowel movements, dizziness, or weakness afterward. If you have any of these side effects, contact your physician immediately. Read your discharge instructions carefully. Medications such as blood-thinners may need to be stopped for a short time after having your colonoscopy, especially if a biopsy was performed or polyps were removed. Full recovery by the next day is normal and expected and you may return to your regular activities.

This is my second colonoscopy procedure and I know all about the procedure. The best thing to do when they insert the tube is to relax and just try to sleep while it's done. They will also inflate your colon while their doing this, so just relax the best you can and try not to pass gas because it will hurt more. Just think pleasant thoughts and it will be over before you know it. I think they will hook you up to an IV so you don't become dehydrated from not eating any food from the previous day. Just a strictly liquid diet and maybe B/P pills and a sip of water and NOTHING else. The colon has to be totally cleaned out.

A little info I think should be considered about this drug Versed ( Midazolam ) that is used for Sedation for many medical procedures..Sedation and General Anesthesia are not the same and quite a few people being given Sedation
think they are being given General Anesthesia!
There is simply no good or valid reason to ever purposely induce amnesia during a medical procedure. It is only a recent development in medical thinking that amnesia is somehow a "benefit" to the patient. On occasion some
some patients will remember a bad experience. Forgetting does not mean it did not happen!!
I feel that if people were aware of the effects of this drug they would Opt For Another Drug!
Erasing someones memory of what was done to them is wrong!!
In fact, many people who use Versed for " IV Sedation,Conscious Sedation" Twilight Sedation, during a procedure are Awake For The Entire Procedure but remember nothing, often Believing They Were "Out" the whole time.
Versed (Midazolam) is an amnestic. It is also commonly used for minor procedures like setting broken bones,colonoscopies,endoscopies, dental procedures like extractions,conscious sedation,twilight sleep, so that patients won't remember pain and discomfort.HOWEVER THAT DOES NOT MEAN THAT THOSE SENSATIONS WILL NOT BE EXPERIENCED!!!!
A note from an anesthesiologist
I agree that using midazolam alone in painful situations is wrong. I've heard people getting colonoscopies and screaming, and maybe they remember, maybe they don't.
A note I got from someone on Yahoo Answers who did have a bad experience..This is very disconcerting... My sister said she heard me screaming from the waiting room but assumed it wasn't me. When we left we heard another female patient screaming. I did a lot of research since your post, thanks so much for the info.
Here is a note from a Dentist Who uses Versed
I've used Versed 1000+ times during oral surgery procedures and I've never had a complaint. It's a miracle drug because it is safe and it causes you to not remember an unpleasant experience. My answer to him is isn't it better to have not experienced the pain than to have forgot it. No wonder you have had no complaints they have no memory of the procedure.....
I feel that giving a drug for amnesia is cruel I would not want it done to me!
A strange development in medical thinking that it's okay for a patient to have
pain as long as they don't remember it and think they slept thru the procedure..
Here is a link for some info

You probably won't lose much weight and if you do, you'll gain it back. It isn't like a colonic where it sucks you out, you will have to drink special stuff a day before that will..well..give you the runs so don't go too far from home. You aren't away, they will sedate you. They should have told you all of this when making the appointment. You can't eat 24 hours before hand either.

I had one recently and you will be given something to clean out your colon the evening before the procedure. I was not awake for mine and I think that is the usual procedure , as for weight loss . there was no significant loss and ,of course you would regain it as soon as you resumed eating after the procedure
