What is a Colonoscopy?

The large intestine or the colon helps in the absorption of water and nutrients from the residual food waste before it gets eliminated. From benign polyps, infections, to cancerous growths, many issues can impact the functioning of the colon.

A colonoscopy is a diagnostic procedure that helps the doctor detect the problems that affect the colon and initiate the appropriate treatment. It is a highly valuable tool for detecting colorectal cancers and precancerous growths. At Huntington Colorectal Surgeons, we strongly believe and advocate for a regular colonoscopy to screen for colorectal cancer.

A colonoscopy may also be recommended:

  • To evaluate the root cause of dark/bloody stools or rectal bleeding
  • To determine the cause of abdominal pain or chronic diarrhea
  • To evaluate iron deficiencies and sudden, unexplained weight loss
  • To study the colon if abnormal test results are obtained from other imaging tests including MRI, CT, and other X-rays
  • To treat and monitor Inflammatory Bowel Disease

Preparing for
your colonoscopy

The experienced surgeons at Huntington Colorectal Surgeons in Pasadena are committed to patient education and invest in ensuring that patients understand the need for a colonoscopy, the preparation process as well as what they can expect during the procedure. We provide detailed instructions on preparing for the procedure, which typically begins several days before the procedure. This may include consuming a low fiber diet that helps the colon eliminate fecal waste in addition to a clear liquid diet a day before the procedure to ensure there is no residual waste in the colon. A laxative medication is also given for most patients a night before the colonoscopy. These steps are vital because they help the doctor evaluate the colon thoroughly and accurately detect any minor or major abnormalities, including tumors, polyps, an infection, or inflammation in colonic tissues.


The colonoscopy is performed in the GI endoscopy suite at Huntington Hospital. Before the procedure, a sedative is administered to enhance the patient’s comfort. The colonoscope is then carefully inserted through the rectum or anus. The colonoscope is a flexible, thin endoscopic instrument that helps in examining the colon and rectum. The tool has a lighted digital camera attached to it that illuminates every inch of the colonic and rectal walls. If needed, the doctor uses specialized tools to remove polyps or tissue samples for further testing or biopsies. These tools can include swabs or forceps that are inserted through the colonoscope to remove samples.

The procedure is completed generally within 30 to 45 minutes, while it can take longer depending on the extent of the area that needs examination.

Our extensive experience and skills ensure that the procedure is extremely safe while we advise on any medication to optimize your comfort during and after the procedure.

After the colonoscopy, the doctor recommends resting for the day. Any minimal side effects such as gas, bloating or cramping subside within 24 hours.
