Colonoscopy and Screening Westbury New York

Colonoscopy is a procedure used to see inside the colon and rectum. Colonoscopy can detect inflamed tissue, ulcers, and abnormal growths. The procedure is used to look for early signs of colorectal cancer and can help doctors diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the anus, and weight loss.

How to Prepare for Colonoscopy

The doctor usually provides written instructions about how to prepare for colonoscopy. The process is called a bowel prep. Generally, all solids must be emptied from the gastrointestinal tract by following a clear liquid diet for 1 to 3 days before the procedure. Patients should not drink beverages containing red or purple dye. Acceptable liquids include

  • fat-free bouillon or broth
  • strained fruit juice
  • water
  • plain coffee
  • plain tea
  • sports drinks, such as Gatorade
  • gelatin

A laxative or an enema may be required the night before colonoscopy. A laxative is medicine that loosens stool and increases bowel movements. Laxatives are usually swallowed in pill form or as a powder dissolved in water. An enema is performed by flushing water, or sometimes a mild soap solution, into the anus using a special wash bottle.

Patients should inform the doctor of all medical conditions and any medications, vitamins, or supplements taken regularly, including

  • aspirin
  • arthritis medications
  • blood thinners
  • diabetes medications
  • vitamins that contain iron

Driving is not permitted for 24 hours after colonoscopy to allow the sedative time to wear off. Before the appointment, patients should make plans for a ride home.

After Your Procedure

At what age should routine colonoscopy begin?

Routine colonoscopy to look for early signs of cancer should begin at age 50 for most people—earlier if there is a family history of colorectal cancer, a personal history of inflammatory bowel disease, or other risk factors. The doctor can advise patients about how often to get a colonoscopy.
