What is a Colonoscopy

A colonoscopy involves the examination of the entire Colon and possibly cannulation of the terminal ileum. Gastroenterologists (sometime called colonoscopy doctors / GI Doctors / Endoscopy Doctors) use colonoscopies to detect changes or abnormalities throughout the large intestine (colon) and rectum.

Colonoscopies are considered by the medical community the gold standard when it comes to colon cancer screening. With this procedure gastroenterologists (colonoscopy doctors) are able to view the entire length of your colon to evaluate the health of your digestive tract using a long, flexible tube called a colonoscope, inserted through the rectum.

A micro-camera attached to the tube enables the physician to see any abnormalities and address them. For example, if any polyps are discovered during the procedure, the doctor can remove the polyps during the procedure.

A colonoscopy can help your doctor explore possible causes of abdominal pain, rectal bleeding, chronic constipation, chronic diarrhea and other intestinal problems.

The vast majority of colonoscopies are performed as part of important screening programs to determine if there is the presence of colon cancer, which is why it is important to schedule a consultation with colonoscopy doctors for preventative health.

If it is necessary, polyps and other types of abnormal tissue can be tested during a colonoscopy by taking tissue samples (biopsies). Also, it is important to remember that biopsies are taken for many reasons, and they do not necessarily indicate cancer.

Most colonoscopies are performed to investigate the cause of abdominal pain, blood in the stool, a change in bowel habit, diarrhea, or an abnormality found on X-rays or a CT scan.

How often a person should go for a colonoscopy depends on a variety of factors. However, a widely accepted recommendation has been that even healthy people should undergo a colonoscopy at age 40, and every five years after that. We suggest asking our gastroenterologists (aka colonoscopy doctors / GI Doctors / Endoscopy Doctors ) for more information.


During a colonoscopy, you will be sedated, during which time your gastroenterologist will insert a specialized medical instrument known as a colonoscope into your rectum, which is about a half inch in diameter, or the size of an average stool.

The colonoscope is passed through the rectum and navigated through the large intestine, during which your physician will be looking for any abnormalities. During this process, air may be pumped gently into the colon to inflate it, making easier to navigate and giving a better view of the colon lining to your physician. Also, at RGC our physicians use HD colonscopes, which enhances visual clarity of the colon.

In addition to observing the bowel for abnormalities, and if necessary during a colonoscopy, your physician may complete biopsies, remove polyps, coagulate bleeding vessel, remove foreign bodies, as well as dilate strictures, and other treatment or diagnostic procedures. All the prior mentioned procedures are painless.

WHAT TO EXPECT when having a colonscopy

The number one thing to remember is not to worry! Our gastroenterologists (colonoscopy doctors / GI Doctors / Endoscopy Doctors) are highly experienced physicians who have completed thousands of colonoscopies, and are considered by colleagues to be the best doctor for colonoscopy. Also, you will have an entire medical team from nurses to physicians who will provide you with the astute attention so stay informed.

When you arrive, you’ll be welcomed by our thoughtful staff and a dedicated team of experts that deliver personalized care. To add to your comfort level, we work to schedule the same physicians and nursing staff with the patient throughout all your appointments at the center. In this way, the staff gets to understand the patient’s concerns and conditions, and you get to know the persons taking care of you on a personal level.

Also, we strive to make your visit as hassle-free as possible. We accurately schedule visits in advance, provide convenient on-site parking, and keep your waiting period to an absolute minimum.

This is achieved by the fact that no emergency procedures are placed in front of your scheduled time (such as in most hospitals). Also, we do not double-book patient appointments, when you are scheduled to be treated that time is assigned only to you.

When undergoing a colonoscopy, the following will apply to your colonoscopy procedural visit:

  • Before any procedure, our staff will meet with you to address any last-minute questions you may have.
  • You will need to maintain a clear liquid diet for an entire day before the procedure date. Also, the liquids most not contain dark color dies in it such as black cola, red or purple beverages, etc.
  • Also, in preparation for your colonoscopy, you will be required to take a “colo-preparation” supplement which acts like a strong laxative used to clear the colon of debris. During your colonoscopy, your physician will be examining the large bowel for the finest details which could prove life-saving, which is why completing a thorough bowel preparation prior to the procedure is so important.
  • Prior to the procedure, you will get changed into one our fresh medical gowns using our private restrooms or a private patient changing area.
  • Once you have changed into the medical gown, you will relax and lay down on a padded procedure gurney, and you will be transported a short distance to our modern operating room.
  • In the operating room, you will meet with your gastroenterologist before your colonoscopy to discuss the procedure, if you would like, and thereafter be administered sedation so that the procedure may commence.
    • When being sedated, you will receive the highest quality anesthesia administered by highly experienced professionals who will standby you to monitor your sedation throughout the entire procedure.
  • The procedure itself will take between 20 to 30 minutes.
  • After the procedure, you will be brought back into the post-anesthesia recovery area where you will relax until the sedation has worn off.
    • After speaking with most patients about their procedure, they universally comment (paraphrasing of course); “I remember getting changed, laying on the gurney, meeting with my doctor and waking up waiting for the procedure to start.” Once they find out the procedure was completed already, there is usually a couple of chuckles they have with our staff.
  • With all that being said, once you are alert from your anesthesia, fully dressed and comfortable, you will meet with your physician to discuss the procedure results, before heading home.
    • Since you will be sedated for the procedure, you’ll need someone to drive you home even after the sedation has initially worn off. Even though you might feel fine, your reflexes may be slower than usual until the anesthesia is entirely out of your system. This can take between 1 to 3 hours after the procedure.
  • Most patients can return to normal eating habits immediately after an endoscopic procedure.

What is Gastroenterology?

Gastroenterology (GI) is the study of gastrointestinal functions, and the diagnosis, treatment and management of diseases of the gastrointestinal tract, including key organs such as the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts, and liver.

Gastroenterology is one of the foremost preventative medicine sciences, and it’s essential to the screening of intestinal cancer, as well as diagnosing and managing digestive and nutritional health diseases.

Digestion is a complex series of events which begin at the mouth and continues through 23 feet of the digestive system. Digestion is a truly amazing organic and vibrant living process that turns nutrients from the foods and liquids we ingest into energy, while at the same time, removing waste from our bodies.

Transported to our organs by our bloodstream, the energy extracted from our food and liquids provide us fuel to support healthy organ functions and daily activities.

At Regional Gastrointestinal Consultants, our gastroenterologists, are regarded by many of their peers as some of the best gastroenterology doctors. We have dedicated our resources and professional lives to ensure that our patients have healthy digestive tracts to live full and happy lives.
